Web Security Overview
Supported and well configured
HTTPS

Web sites need to use encryption to help their visitors know they're in the right place, as well as provide confidentiality and content integrity. Sites that don't support HTTPS may expose sensitive data and have their pages modified and subverted.

For all sites VERY IMPORTANT medium EFFORT
Supported and well configured
HTTPS Redirection

To deploy HTTPS properly, web sites must redirect all unsafe (plaintext) traffic to the encrypted variant. This approach ensures that no sensitive data is exposed and that further security technologies can be activated.

For all sites VERY IMPORTANT low EFFORT
Warning
HTTP Strict Transport Security

HTTP Strict Transport Security (HSTS) is an HTTPS extension that instructs browsers to remember sites that use encryption and enforce strict security requirements. Without HSTS, active network attacks are easy to carry out.
There are issues with this site's HSTS configuration.

For important sites VERY IMPORTANT medium EFFORT
Supported and well configured
HSTS Preloaded

HSTS Preloading is informing browsers in advance about a site's use of HSTS, which means that strict security can be enforced even on the first visit. This approach provides best HTTPS security available today.

For important sites VERY IMPORTANT medium EFFORT
Not supported
Content Security Policy

Content Security Policy (CSP) is an additional security layer that enables web sites to control browser behavior, creating a safety net that can counter attacks such as cross-site scripting.

For important sites IMPORTANT high EFFORT
Email Security Overview
Warning
STARTTLS

All hosts that receive email need encryption to ensure confidentiality of email messages. Email servers thus need to support STARTTLS, as well as provide decent TLS configuration and correct certificates.
There are issues with this site's SMTP configuration.

For all sites VERY IMPORTANT low EFFORT
Supported and well configured
SPF

Sender Policy Framework (SPF) enables organizations to designate servers that are allowed to send email messages on their behalf. With SPF in place, spam is easier to identify.

For important sites IMPORTANT low EFFORT
Supported and well configured
DMARC

Domain-based Message Authentication, Reporting, and Conformance (DMARC) is a mechanism that allows organizations to specify how unauthenticated email (identified using SPF and DKIM) should be handled.

For important sites IMPORTANT low EFFORT

DNS Zone

The global DNS infrastructure is organized as a series of hierarchical DNS zones. The root zone hosts a number of global and country TLDs, which in turn host further zones that are delegated to their customers. Each organization that controls a zone can delegate parts of its namespace to other zones. In this test we perform detailed inspection of a DNS zone, but only if the host being tested matches the zone.

Test passed
Everything seems to be well configured. Well done.

Nameserver Names

Nameservers can be referred to by name and by address. In this section we show the names, which can appear in the NS records, the referrals from the parent zone, and the SOA record. In some situations, servers from the parent zone respond authoritatively, in which case we will include them in the list as well.

Nameserver Addresses

This section shows the configuration of all discovered nameservers by their IP address. To find all applicable nameservers, we inspect the parent zone nameservers for names and glue and then the tested zone nameservers for NS records. We then resolve all discovered names to IP addresses. Finally, we test each address individually.

Start of Authority (SOA) Record

Start of Authority (SOA) records contain administrative information pertaining to one DNS zone, especially the configuration that's used for zone transfers between the primary nameserver and the secondaries. Only one SOA record should exist, with all nameservers providing the same information.

The domain name of the primary nameserver for the zone. Also known as MNAME.Primary nameserver ns3.cloudflare.com.
Email address of the persons responsible for this zone. Also known as RNAME.Admin email dns.cloudflare.com.
Zone serial or version number.Serial number -1955670071
The length of time secondary nameservers should wait before querying the primary for changes.Refresh interval 10,000 seconds (about 2 hours 46 minutes)
The length of time secondary nameservers should wait before querying an unresponsive primary again.Retry interval 2,400 seconds (about 40 minutes)
The length of time after which secondary nameservers should stop responding to queries for a zone, assuming no updates were obtained from the primary.Expire interval 604,800 seconds (about 7 days)
TTL for purposes of negative response caching. Negative cache TTL 300 seconds (about 5 minutes)
Time To Live (TTL) indicates for how long a record remains valid. SOA record TTL 300 seconds (about 5 minutes)

DNS Records

Correctly functioning name servers are necessary to hold and distribute information that's necessary for your domain name to operate correctly. Examples include converting names to IP addresses, determining where email should go, and so on. More recently, the DNS is being used to communicate email and other security policies.

Test passed
Everything seems to be well configured. Well done.

DNSSEC

DNSSEC is an extension of the DNS protocol that provides cryptographic assurance of the authenticity and integrity of responses; it's intended as a defense against network attackers who are able to manipulate DNS to redirect their victims to servers of their choice. DNSSEC is controversial, with the industry split largely between those who think it's essential and those who believe that it's problematic and unnecessary.

Test passed
Everything seems to be well configured. Well done.

Analysis

Good
DNSSEC is well configured
Good. This domain name has well-configured DNSSEC.

Useful DNSSEC Tools

Certification Authority Authorization

CAA (RFC 8659) is a new standard that allows domain name owners to restrict which CAs are allowed to issue certificates for their domains. This can help to reduce the chance of misissuance, either accidentally or maliciously. In September 2017, CAA became mandatory for CAs to implement.

Test passed
Everything seems to be well configured. Well done.

Analysis

Good
CAA policy found
Good. This domain name uses CAA to restrict which CAs are allowed to issue certificates for it.
Good
Policy uses reporting
Great. This policy uses reporting, which means that your contact information is available should someone need to contact you about a CAA violation. Do note that you're not guaranteed to be notified, given that CAs generally don't support notifications yet.

Email (SMTP)

An internet hostname can be served by zero or more mail servers, as specified by MX (mail exchange) DNS resource records. Each server can further resolve to multiple IP addresses, for example to handle IPv4 and IPv6 clients. Thus, in practice, hosts that wish to receive email reliably are supported by many endpoint.

Test passed, but there are warnings

Notice
Some SMTP server assessments have been retrieved from cache
Some SMTP server assessment results have been retrieved from our cache. Because many hosts point to the same SMTP servers, we use a short-term cache to avoid testing the same SMTP servers over and over again.

Latest cache timestamp: 29 Apr 2024 23:03 UTC

Earliest cache timestamp: 29 Apr 2024 17:54 UTC

Notice
Some SMTP server assessments contain partial information
Comprehensive TLS assessments require many connections, which is exactly what many SMTP servers don't like. We implement a two-tier assessment approach. To give you some results as fast as possible, we perform shallow assessments that use only one connection per SMTP server. We then have a background process that performs complete assessments slowly, trying to accommodate each server individually. The results presented here contain partial information. If you come back later we may be able to provide complete assessment resuls.

Email TLS (SMTP)

Transport Layer Security (TLS) is the most widely used encryption protocol on the Internet. In combination with valid certificates, servers can establish trusted communication channels even with users who have never visited them before. Network attackers can't uncover what is being communicated, even when they can see all the traffic.

Test passed, but there are warnings
Some aspect of your site's configuration require your attention.
Some TLS and PKI information shown may have been retrieved from cache. The notes provide more information.

Analysis

Good
TLS 1.2 supported
Good. This server supports TLS 1.2, which can provide strong security when configured correctly. This version of the TLS protocol is necessary to provide good security with a wide range of clients that don't yet support TLS 1.3.
Good
Strong key exchange detected
Excellent. All cipher suites on this server rely on strong key exchange. The sweet spot is 2048 bits for DHE and 256 bits for ECDHE. Putting ECDHE suites first guarantees best security and best performance.
Notice
Partial results shown
SMTP assessments usually take a long time. To get you some results faster, we initially perform shallow checks. If you come back later we may be able to show you complete results.
Notice
Relaxed TLS assessment criteria applied to SMTP on port 25
We apply relaxed assessment criteria when evaluating TLS configuration of SMTP servers on port 25. This is because most delivery agents fall back to delivering via plaintext on failure to negotiate encryption. Some configuration elements that can be abused to attack other ports and protocols (e.g., SSLv2 and export cipher suites) are penalized in the same way as for other protocols. We will review this policy in the future.

Analysis

Good
TLS 1.2 supported
Good. This server supports TLS 1.2, which can provide strong security when configured correctly. This version of the TLS protocol is necessary to provide good security with a wide range of clients that don't yet support TLS 1.3.
Powerup!
Server doesn't enforce cipher suite preferences
Servers that don't enforce cipher suite preferences select the first cipher suite they support from the list provided by clients. This approach doesn't guarantee that best-possible cipher suite is negotiated.
Error
Insecure anonymous suites supported
Anonymous cipher suites are insecure because they don't authenticate servers. As a result, an active network adversary can silently intercept all communication. These suites should be removed as soon as possible.

First encountered suite: TLS_ECDH_anon_WITH_AES_128_CBC_SHA

Error
Insecure key exchange detected
This server uses key exchange parameters that are insecure. When using the ephemeral Diffie-Hellman key exchange (DHE), parameters below 1024 bits are considered insecure. For sufficient security, use 2048-bit parameters. It is generally not advisable to use stronger DHE key exchange because there is a measurable performance penalty and there is no meaningful increase in security. A well-configured TLS server should generally prefer the faster ECDHE key exchange anyway. When it comes to ECDHE, aim for at least 256 bits; anything below 200 bits is weak. For best results, use secp256r1 and secp384r1, which are required in practice, and x25519 as an emerging standard.

Key exchange length: 0

Key exchange algorithm: DH_anon

Example suite: TLS_DH_anon_WITH_AES_128_CBC_SHA

Warning
Reconfigure server to use forward secrecy and authenticated encryption
Even though this server supports TLS 1.2, the cipher suite configuration is suboptimal. We recommend that you reconfigure the server so that the cipher suites providing forward secrecy (ECDHE or DHE in the name, in this order of preference) and authenticated encryption (GCM or CHACHA20 in the name) are at the top. The server must also be configured to select the best-available suite.
Notice
Relaxed TLS assessment criteria applied to SMTP on port 25
We apply relaxed assessment criteria when evaluating TLS configuration of SMTP servers on port 25. This is because most delivery agents fall back to delivering via plaintext on failure to negotiate encryption. Some configuration elements that can be abused to attack other ports and protocols (e.g., SSLv2 and export cipher suites) are penalized in the same way as for other protocols. We will review this policy in the future.
Good
DHE server parameter not reused
This server does not reuse the private value used for the Diffie-Hellman key exchange.

Email Certificates (SMTP)

A certificate is a digital document that contains a public key, some information about the entity associated with it, and a digital signature from the certificate issuer. It’s a mechanism that enables us to exchange, store, and use public keys. Being able to reliably verify the identity of a remote server is crucial in order to achieve secure encrypted communication.

Everything seems to be well configured. Well done.

Email DANE (SMTP)

DNS-based Authentication of Named Entities (DANE) is a bridge between DNSSEC and TLS. In one possible scenario, DANE can be used for public key pinning, building on an existing publicly-trusted certificate. In another approach, it can be used to completely bypass the CA ecosystem and establish trust using DNSSEC alone.

Feature not applicable, not implemented, or disabled
Your server doesn't support this feature.

SPF

Sender Policy Framework (SPF) is a protocol that allows domain name owners to control which internet hosts are allowed to send email on their behalf. This simple mechanism can be used to reduce the effect of email spoofing and cut down on spam.

DMARC

Domain-based Message Authentication, Reporting, and Conformance (DMARC) is a scalable mechanism by which a mail-originating organization can express domain-level policies and preferences for message validation, disposition, and reporting, that a mail-receiving organization can use to improve mail handling.

MTA Strict Transport Security

SMTP Mail Transfer Agent Strict Transport Security (MTA-STS) is a mechanism enabling mail service providers to declare their ability to receive Transport Layer Security (TLS) secure SMTP connections, and to specify whether sending SMTP servers should refuse to deliver to MX hosts that do not offer TLS with a trusted server certificate.

Feature not applicable, not implemented, or disabled
Your server doesn't support this feature.

SMTP TLS Reporting

SMTP TLS Reporting (RFC 8460), or TLS-RPT for short, describes a reporting mechanism and format by which systems sending email can share statistics and specific information about potential failures with recipient domains. Recipient domains can then use this information to both detect potential attacks and diagnose unintentional misconfigurations. TLS-RPT can be used with DANE or MTA-STS.

Feature not applicable, not implemented, or disabled
Your server doesn't support this feature.

HTTP (80)

To observe your HTTP implementation, we submit a request to the homepage of your site on port 80, follow all redirections (even when they take us to other domain names), and record the returned HTTP headers.

WWW TLS

Transport Layer Security (TLS) is the most widely used encryption protocol on the Internet. In combination with valid certificates, servers can establish trusted communication channels even with users who have never visited them before. Network attackers can't uncover what is being communicated, even when they can see all the traffic.

Test passed
Everything seems to be well configured. Well done.

Analysis

Notice
Deprecated protocols supported
TLS 1.0 and TLS 1.1 are deprecated protocols that should be disabled if possible. TLS 1.0, in particular, is a weak older protocol that has many weaknesses. Sites that aim at a wide audience might still need to support TLS 1.0 for the time being, because many older clients don't support newer protocol versions. Sites with a modern user base might be able to disable TLS 1.0 even now. We recommend that you enable logging of encryption parameters, after which you can examine your protocol usage and make a decision with confidence. As of July 2018, PCI DSS doesn't allow use of TLS 1.0. Exceptions apply in some cases.
Good
TLS 1.3 supported
Excellent. This server supports TLS 1.3, which is the latest revision of the TLS protocol and a significant improvement over earlier versions. Developed over a period of several years and extensively analyzed prior to the release, TLS 1.3 removed insecure features, and improved both security and performance.
Good
TLS 1.2 supported
Good. This server supports TLS 1.2, which can provide strong security when configured correctly. This version of the TLS protocol is necessary to provide good security with a wide range of clients that don't yet support TLS 1.3.
Good
Strong key exchange detected
Excellent. All cipher suites on this server rely on strong key exchange. The sweet spot is 2048 bits for DHE and 256 bits for ECDHE. Putting ECDHE suites first guarantees best security and best performance.
Good
Server prefers forward secrecy and authenticated encryption suites
Excellent. Not only does this server enforce its server preference, but it also has at the top of the list suites that support both forward secrecy and authenticated encryption. This is the best TLS 1.2 can offer.
Good
Server enforces cipher suite preferences
Excellent. This server enforces server cipher suite preference, which means that it is able to select the best suite from the options submitted by clients. Combined with a well designed list of supported cipher suites, this settings enables negotiation of best security.
Good
All TLS connections with this server satisfy Apple's CT requirements
All TLS connections established with this server satisfy Chrome's CT requirements, using certificate, TLS extension, or OCSP response as SCT transport method.

Sites that aim at a wide audience might still need to support TLS 1.0 for the time being, because many older clients don't support newer protocol versions. Sites with a modern user base might be able to disable TLS 1.0 even now. We recommend that you enable logging of encryption parameters, after which you can examine your protocol usage and make a decision with confidence. As of July 2018, PCI DSS doesn't allow use of TLS 1.0. Exceptions apply in some cases.

TLS 1.3 supported
Excellent. This server supports TLS 1.3, which is the latest revision of the TLS protocol and a significant improvement over earlier versions. Developed over a period of several years and extensively analyzed prior to the release, TLS 1.3 removed insecure features, and improved both security and performance.
Good
TLS 1.2 supported
Good. This server supports TLS 1.2, which can provide strong security when configured correctly. This version of the TLS protocol is necessary to provide good security with a wide range of clients that don't yet support TLS 1.3.
Good
Strong key exchange detected
Excellent. All cipher suites on this server rely on strong key exchange. The sweet spot is 2048 bits for DHE and 256 bits for ECDHE. Putting ECDHE suites first guarantees best security and best performance.

Analysis

Notice
Deprecated protocols supported
TLS 1.0 and TLS 1.1 are deprecated protocols that should be disabled if possible. TLS 1.0, in particular, is a weak older protocol that has many weaknesses. Sites that aim at a wide audience might still need to support TLS 1.0 for the time being, because many older clients don't support newer protocol versions. Sites with a modern user base might be able to disable TLS 1.0 even now. We recommend that you enable logging of encryption parameters, after which you can examine your protocol usage and make a decision with confidence. As of July 2018, PCI DSS doesn't allow use of TLS 1.0. Exceptions apply in some cases.
Good
TLS 1.3 supported
Excellent. This server supports TLS 1.3, which is the latest revision of the TLS protocol and a significant improvement over earlier versions. Developed over a period of several years and extensively analyzed prior to the release, TLS 1.3 removed insecure features, and improved both security and performance.
Good
TLS 1.2 supported
Good. This server supports TLS 1.2, which can provide strong security when configured correctly. This version of the TLS protocol is necessary to provide good security with a wide range of clients that don't yet support TLS 1.3.
Good
Strong key exchange detected
Excellent. All cipher suites on this server rely on strong key exchange. The sweet spot is 2048 bits for DHE and 256 bits for ECDHE. Putting ECDHE suites first guarantees best security and best performance.
Good
Server prefers forward secrecy and authenticated encryption suites
Excellent. Not only does this server enforce its server preference, but it also has at the top of the list suites that support both forward secrecy and authenticated encryption. This is the best TLS 1.2 can offer.
Good
Server enforces cipher suite preferences
Excellent. This server enforces server cipher suite preference, which means that it is able to select the best suite from the options submitted by clients. Combined with a well designed list of supported cipher suites, this settings enables negotiation of best security.
Good
All TLS connections with this server satisfy Apple's CT requirements
All TLS connections established with this server satisfy Chrome's CT requirements, using certificate, TLS extension, or OCSP response as SCT transport method.

Analysis

Notice
Deprecated protocols supported
TLS 1.0 and TLS 1.1 are deprecated protocols that should be disabled if possible. TLS 1.0, in particular, is a weak older protocol that has many weaknesses. Sites that aim at a wide audience might still need to support TLS 1.0 for the time being, because many older clients don't support newer protocol versions. Sites with a modern user base might be able to disable TLS 1.0 even now. We recommend that you enable logging of encryption parameters, after which you can examine your protocol usage and make a decision with confidence. As of July 2018, PCI DSS doesn't allow use of TLS 1.0. Exceptions apply in some cases.
Good
TLS 1.3 supported
Excellent. This server supports TLS 1.3, which is the latest revision of the TLS protocol and a significant improvement over earlier versions. Developed over a period of several years and extensively analyzed prior to the release, TLS 1.3 removed insecure features, and improved both security and performance.
Good
TLS 1.2 supported
Good. This server supports TLS 1.2, which can provide strong security when configured correctly. This version of the TLS protocol is necessary to provide good security with a wide range of clients that don't yet support TLS 1.3.
Good
Strong key exchange detected
Excellent. All cipher suites on this server rely on strong key exchange. The sweet spot is 2048 bits for DHE and 256 bits for ECDHE. Putting ECDHE suites first guarantees best security and best performance.
Good
Server prefers forward secrecy and authenticated encryption suites
Excellent. Not only does this server enforce its server preference, but it also has at the top of the list suites that support both forward secrecy and authenticated encryption. This is the best TLS 1.2 can offer.
Good
Server enforces cipher suite preferences
Excellent. This server enforces server cipher suite preference, which means that it is able to select the best suite from the options submitted by clients. Combined with a well designed list of supported cipher suites, this settings enables negotiation of best security.
Good
All TLS connections with this server satisfy Apple's CT requirements
All TLS connections established with this server satisfy Chrome's CT requirements, using certificate, TLS extension, or OCSP response as SCT transport method.

Analysis

Notice
Deprecated protocols supported
TLS 1.0 and TLS 1.1 are deprecated protocols that should be disabled if possible. TLS 1.0, in particular, is a weak older protocol that has many weaknesses. Sites that aim at a wide audience might still need to support TLS 1.0 for the time being, because many older clients don't support newer protocol versions. Sites with a modern user base might be able to disable TLS 1.0 even now. We recommend that you enable logging of encryption parameters, after which you can examine your protocol usage and make a decision with confidence. As of July 2018, PCI DSS doesn't allow use of TLS 1.0. Exceptions apply in some cases.
Good
TLS 1.3 supported
Excellent. This server supports TLS 1.3, which is the latest revision of the TLS protocol and a significant improvement over earlier versions. Developed over a period of several years and extensively analyzed prior to the release, TLS 1.3 removed insecure features, and improved both security and performance.
Good
TLS 1.2 supported
Good. This server supports TLS 1.2, which can provide strong security when configured correctly. This version of the TLS protocol is necessary to provide good security with a wide range of clients that don't yet support TLS 1.3.
Good
Strong key exchange detected
Excellent. All cipher suites on this server rely on strong key exchange. The sweet spot is 2048 bits for DHE and 256 bits for ECDHE. Putting ECDHE suites first guarantees best security and best performance.

Analysis

Notice
Deprecated protocols supported
TLS 1.0 and TLS 1.1 are deprecated protocols that should be disabled if possible. TLS 1.0, in particular, is a weak older protocol that has many weaknesses. Sites that aim at a wide audience might still need to support TLS 1.0 for the time being, because many older clients don't support newer protocol versions. Sites with a modern user base might be able to disable TLS 1.0 even now. We recommend that you enable logging of encryption parameters, after which you can examine your protocol usage and make a decision with confidence. As of July 2018, PCI DSS doesn't allow use of TLS 1.0. Exceptions apply in some cases.
Good
TLS 1.3 supported
Excellent. This server supports TLS 1.3, which is the latest revision of the TLS protocol and a significant improvement over earlier versions. Developed over a period of several years and extensively analyzed prior to the release, TLS 1.3 removed insecure features, and improved both security and performance.
Good
TLS 1.2 supported
Good. This server supports TLS 1.2, which can provide strong security when configured correctly. This version of the TLS protocol is necessary to provide good security with a wide range of clients that don't yet support TLS 1.3.
Good
Strong key exchange detected
Excellent. All cipher suites on this server rely on strong key exchange. The sweet spot is 2048 bits for DHE and 256 bits for ECDHE. Putting ECDHE suites first guarantees best security and best performance.
Good
Server prefers forward secrecy and authenticated encryption suites
Excellent. Not only does this server enforce its server preference, but it also has at the top of the list suites that support both forward secrecy and authenticated encryption. This is the best TLS 1.2 can offer.
Good
Server enforces cipher suite preferences
Excellent. This server enforces server cipher suite preference, which means that it is able to select the best suite from the options submitted by clients. Combined with a well designed list of supported cipher suites, this settings enables negotiation of best security.
Good
All TLS connections with this server satisfy Apple's CT requirements
All TLS connections established with this server satisfy Chrome's CT requirements, using certificate, TLS extension, or OCSP response as SCT transport method.

SCT transports: CERT

Notice
DHE suites not supported
This server doesn't support the Diffie-Hellman (DH) key exchange.

WWW Certificates

A certificate is a digital document that contains a public key, some information about the entity associated with it, and a digital signature from the certificate issuer. It’s a mechanism that enables us to exchange, store, and use public keys. Being able to reliably verify the identity of a remote server is crucial in order to achieve secure encrypted communication.

Test passed
Everything seems to be well configured. Well done.

Certificate Trust

Determining whether a certificate is considered valid is a complicated process that depends on the exact configuration of the validating party. For trust to be established, the certificate must form a chain that ends with a trusted root. In this section we evaluate the server's certificate against major root stores.

Certificate Chain

For a server certificate to be valid, it must be presented as part of a complete and valid certificate chain. The last certificate in the chain should be the root and is usually not included in the configuration.

Analysis

Good
Certificate chain is correct
Good. This chain contains all the right certificates and in the right order.

DANE (443)

DNS-based Authentication of Named Entities (DANE) is a bridge between DNSSEC and TLS. In one possible scenario, DANE can be used for public key pinning, building on an existing publicly-trusted certificate. In another approach, it can be used to completely bypass the CA ecosystem and establish trust using DNSSEC alone.

Feature not applicable, not implemented, or disabled

Cookies

Cookies are small chunks of text that are sent between your browser and a website. They are often essential to the operation of the site and sometimes contain sensitive information. Session cookies sent from secure sites must be explicitly marked as secure to prevent being obtained by active network attackers.

Test passed
Everything seems to be well configured. Well done.

HTTP Cookie: __cf_bm

Cookie value. As far as the cookie RFC is concerned, the value
is an opaque string which only the application should interpret.Value 		GXaGv042TsI9HzBhqlpCzIMcnHXT3zuGSZM1bFgox0c-1714787811-1.0.1.1-GTjz1whagdXd8YPgKq_VKNXXLXgpuWpDRmHFGTpQq5h0xy7Lm8mGkcxL2VSXsMJ7EuNf4sc0f_seSf.lgfibMUGdiZ9yQhVRJxoSQBw42ko
Cookie domain. When domain is implied (not explicitly set in a cookie),
most browsers (but not IE) treat the cookie as host-only, meaning that
no other server can overwrite it.Domain 		www.cloudflare.com
Cookie path. This field can't be used as security measure,
but it could be of use to avoid cookie name collision
in non-adversarial contexts.Path 		/
Cookies are designed to always expire. Session cookies
are truly ephemeral and remain cached until the browser
is closed. The Expires and Max-Age cookie attributes can
be used to specify that a cookie should stay alive for
longer.Expires 		Sat May 04 02:26:51 UTC 2024 (29 minutes)
The HttpOnly flag prevents the cookie from being accessed
from JavaScript, thus making them more difficult
to obtain after a successful XSS attack.HttpOnly
The Secure flag signals to browsers that the cookie
should be transmitted only over an encrypted channel.Secure
Normally, when a browser makes a request to a web site,
it sends all associated cookies. This is not always
desirable, because it might allow third-party sites
to perform site actions under the identity of the user.
This attack is known as Cross-Site Request Forgery.
With SameSite cookies (still in development, but already
supported in some browsers), you can choose to be more
strict. The possible values are 'lax' and 'strict'.SameSite

Analysis

Good
Cookie is secure
Good. This cookie is marked secure, which means that it won't ever be transmitted over plaintext. As such, it's not vulnerable to the Sidejacking attack.

Analysis

Good
All cookies are secure
Great. All observed cookies are marked secure.

Mixed Content

On virtually all web sites, HTML markup, images, style sheets, JavaScript, and other page resources arrive not only over multiple connections but possibly from multiple servers and sites spread across the entire Internet. For a page to be properly encrypted, it’s necessary that all the content is retrieved over HTTPS. In practice, that’s very often not the case, leading to mixed content security problems.

Test passed
Everything seems to be well configured. Well done.

Embedded Resources

In this section we look at the security of all embedded resources. Mixed active content occurs when there are unprotected scripts or styles embedded in a page. This is typically not allowed by modern browsers. Mixed passive content (images, videos and such) are typically allowed, but shouldn't be present.

0 script(s)
  0 out of 0 are secure
0 CSS file(s)
  0 out of 0 are secure
0 media file(s)
  0 out of 0 are secure

Outbound Links

Ideally, an encrypted page should only have links that lead to other encrypted pages. If plaintext links are used, passive network attackers can see where people go after they visit your web site. It's also possible that some sensitive information is leaked in the Referer header.

0 link(s)
  0 out of 0 are encrypted

HTTP Strict Transport Security

HTTP Strict Transport Security (HSTS) vastly improves security of the network encryption layer. With HSTS enabled, browsers no longer allow clicking through certificate warnings errors, which are typically trivial to exploit. Additionally, they will no longer submit insecure (plaintext) requests to the site in question, even if asked.

Test passed, but there are warnings
Some aspect of your site's configuration require your attention.

HSTS Policy  Main host

URL from which this policy was obtained.Location https://www.cloudflare.com/
Specifies policy duration. Once activated, HSTS stays in force
until this time lapses. Browsers update policy cache duration
every time they receive a new HSTS header from a site.max‑age 		31,536,000 seconds (about 1 year)
When present, this directive forces HSTS activation
on allsubdomains. For best security, HSTS should be
deployed on the bare domain name (e.g., example.com)
and all its subdomains.includeSubDomains
Presence of this directive indicates that a web site wishes to
permanently use HSTS and that its policy information should be
preloaded (embedded in browsers).preload

Analysis

Good
Policy is valid
OK. Your HSTS policy uses correct syntax.
Good
Long policy age
Your HSTS policy has a long max-age value, which offers better protection.
Good
Policy covers subdomains
When subdomains are included, network attackers are unable to manufacture arbitrary subdomains to manipulate cookies and trick users.
Notice
Preload directive has no effect here
This policy doesn't enable preloading, but that's all right. The preload directive doesn't have any effect unless it's used on an apex hostname.
Good
Redirection from HTTP to HTTPS to the same host
Good. The redirection from HTTP to HTTPS is to the same host. This approach ensures that HSTS is activated on the hostname when it's accessed via plaintext.
Good
Policy preloaded
Excellent. This host is covered by a preloaded HSTS policy.

Preloaded host: cloudflare.com; includeSubDomains=true

HSTS Policy  Apex host

URL from which this policy was obtained.Location https://cloudflare.com/
Specifies policy duration. Once activated, HSTS stays in force

Powerup!
Preloading not enabled
This policy doesn't give browsers permission to embed it and provide protection even to the first request to the web site. Sites that wish to use preloading can apply at hstspreload.org.
Warning
Redirection from HTTP to HTTPS not to the same host
When HSTS is used, the plaintext port should redirect to the HTTPS variant of the same hostname. This approach ensures that HSTS is enabled on that hostname, even if later the client is sent elsewhere. A redirection to another host is only safe if it is for a parent host that has HSTS with includeSubDomains enabled, but that's not the case here.

Starting point: http://cloudflare.com

Current redirection: https://www.cloudflare.com/

Expected redirection: https://cloudflare.com

Good
Policy preloaded
Excellent. This host is covered by a preloaded HSTS policy.

Preloaded host: cloudflare.com; includeSubDomains=true

HTTP Public Key Pinning

HTTP Public Key Pinning (HPKP) enables site operators to restrict which certificates are considered valid for their domain names. With a valid HPKP configuration, sites can defeat man in the middle (MITM) attacks using fraudulent or misissued certificates. HPKP is an advanced feature, suitable for use by only high-profile web sites.

Feature not applicable, not implemented, or disabled
Your server doesn't support this feature.

Content Security Policy

Content Security Policy (CSP) is a security mechanism that allows web sites control how browsers process their pages. In essence, sites can restrict what types of resources are loaded and from where. CSP policies can be used to defend against cross-site scripting, prevent mixed content issues, as well as report violations for investigation.

Feature not applicable, not implemented, or disabled
Your server doesn't support this feature.

Subresource Integrity

Subresource Integrity (SRI) is a new standard that enables browsers to verify the integrity of embedded page resources (e.g., scripts and stylesheets) when they are loaded from third-party web sites. With SRI deployed, remote resources can be used safely, without fear of them being modified by malicious parties.

Test passed
Everything seems to be well configured. Well done.
No external scripts
  SRI not needed
No external stylesheets
  SRI not needed

Analysis

Good
No remote resources
The homepage of this site doesn't contain any remote resources so SRI is not needed.

Expect CT

Expect-CT is a deprecated response HTTP header designed to enable web sites to monitor problems related to their Certificate Transparency (CT) compliance. Should any CT issues arise, browsers that supported this header will submit reports to the specified reporting endpoint. Chrome was the browser that introduced support for this response header, but later deprecated it and removed it in version 107.

Feature not applicable, not implemented, or disabled
Your server doesn't support this feature.

Analysis

Powerup!
Deploy Expect-CT to enable reporting
An Expect-CT policy enables web sites to monitor for any problems related to their Expect-CT compliance, detecting potentially serious issues quickly. When issues arise, compliant browsers will submit reports to the specified reporting endpoints. Before CT became required for all public certificates the Expect-CT was also used to require CT, but that use case no longer applies.

Frame Options

The X-Frame-Options header controls page framing, which occurs when a page is incorporated into some other page, possibly on a different site. If framing is allowed, attackers can employ clever tricks to make victims perform arbitrary actions on your site; they do this by showing their web site while forwarding the victim's clicks to yours.

Test passed
Everything seems to be well configured. Well done.

Analysis

Info

Name: X-Frame-Options

Value: SAMEORIGIN

Good
Framing allowed from the same origin only
OK. Your site allows page framing only from itself. This should generally be safe, except maybe on sites that host user content.

XSS Protection

Some browsers ship with so-called XSS Auditors, built-in defenses against XSS. Although these defenses work against simple reflective XSS attacks, they can be abused by skillful attackers to add weaknesses to otherwise secure web sites. These dangers are present in both filtering and blocking modes. At this time, the Safari browser ships with its XSS defenses enabled by default. For this reason, the best approach is to explicitly disable this functionality.

Test passed, but there are warnings
Some aspect of your site's configuration require your attention.

Analysis

Info
Header information

Name: X-XSS-Protection

Value: 1; mode=block

Warning
XSS auditor blocking is dangerous
Your configuration requests blocking when XSS attacks are detected, which is potentially dangerous as it allows attackers to selectively disable portions of JavaScript code. The only safe approach is to explicitly disable browser-based XSS protection.

Content Type Options

Some browsers use a technique called content sniffing to override response MIME types provided by HTTP servers and interpret responses as something else (usually HTML). This behavior, which could potentially lead to security issues, should be disabled by attaching an X-Content-Type-Options header to all responses.

Test passed
Everything seems to be well configured. Well done.
