Web Security Overview

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

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

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.

For important sites VERY IMPORTANT medium EFFORT

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

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

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.

For all sites VERY IMPORTANT low EFFORT

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

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	edns.registrar-servers.com.
Email address of the persons responsible for this zone. Also known as RNAME.Admin email	support.namecheap.com.
Zone serial or version number.Serial number	1753368401
The length of time secondary nameservers should wait before querying the primary for changes.Refresh interval	28,800 seconds (about 8 hours)
The length of time secondary nameservers should wait before querying an unresponsive primary again.Retry interval	7,200 seconds (about 2 hours)
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	3,600 seconds (about 1 hour)
Time To Live (TTL) indicates for how long a record remains valid. SOA record TTL	3,600 seconds (about 1 hour)

Analysis

Nameserver addresses should have reverse names

According to RFC 1912, having reverse DNS configuration in place for every nameserver is a best practice that maximizes the chances of correct DNS operation. Further, some anti-spam techniques use reverse name resolution to allow traffic.

Nameserver A and AAAA records should have matching reverse records

According to RFC 1912, nameserver's PTR records must match their A and AAAA records to ensure maximum interoperability.

No problems detected with the zone configuration

Excellent. This DNS zone is in a good working order. No problems detected.

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.

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.

Feature not applicable, not implemented, or disabled

Your server doesn't support this feature.

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.

Feature not applicable, not implemented, or disabled

Your server doesn't support this feature.

Analysis

There is no CAA policy on this domain

CAA policies can be used to restrict which CAs are allowed to issue certificates for a hostname. As such, CAA can be used to enforce an organization-wide policy and to prevent issuance of unauthorized certificates. The CA/Browser forum requires CAs to consult CAA configuration during certificate issuance from September 2017.

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.

Analysis

Limited testing of third-party SMTP servers

We employ limited testing of third-party SMTP servers because they tend to be used by a great many domain names. Because we also continuously test a great many domain names, we want to avoid sending too many near-identical connections to these SMTP servers. It doesn't serve a practical purpose and also tends to get us on their bad side. TLS protocol testing, in particular, requires a lot of connections, which mean that we're often treated like spammers, even though we don't send any email. When testing third-party servers we may check only IP address per SMTP destination. When this is the case, the list of IP addresses shown here may not be complete. Further, in some situations with top services, we may show only the TLS configuration from a representative sample of their servers.

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

Everything seems to be well configured. Well done.

Analysis

Deprecated TLS 1.0 protocol supported

TLS 1.0 is a weak older protocol that should be phased out. 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 decisions with confidence.

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.

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 setting enables negotiation of best security.

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.

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.

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.

DHE server parameter not reused

This server does not reuse the private value used for the Diffie-Hellman key exchange.

Analysis

Deprecated TLS 1.0 protocol supported

TLS 1.0 is a weak older protocol that should be phased out. 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 decisions with confidence.

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.

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 setting enables negotiation of best security.

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.

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.

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.

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.

Test passed

Everything seems to be well configured. Well done.

Analysis

Certificate chain is correct

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

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.

Test passed

Everything seems to be well configured. Well done.

SPF policy is valid

Good. Your SPF policy is syntactically valid.

Policy uses default fail

Excellent. This policy fails hosts that are not allowed to send email for this domain name.

Policy DNS lookups under limit

Good. Your policy stays under the limit of up to 10 DNS queries. The SPF specification Section 4.6.4. requires implementations to limit the total number of DNS queries. Policies that exceed the limit should not be used and may not work in practice.

Lookups: 8

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.

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

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.

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.

Deprecated protocols not supported

Excellent. This server doesn't support any of the deprecated protocol (TLS 1.1 and earlier).

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.

Only strong suites supported

Excellent. This server supports only strong cipher suites, which use strong authenticated encryption and provide forward secrecy.

Analysis

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.

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.

Deprecated protocols not supported

Excellent. This server doesn't support any of the deprecated protocol (TLS 1.1 and earlier).

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.

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.

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 setting enables negotiation of best security.

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

All TLS connections with this server satisfy Chrome'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

Post-quantum key exchange supported

Excellent. This server supports post-quantum cryptography (PQC) and uses it for key exchange. PQC is still in the process of being standardized and deployed. Protecting the key exchange against future quantum computers is considered to be one of the more pressing tasks.

Algorithm: X25519MLKEM768

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.

Analysis

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

Your server doesn't support this feature.

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	MS4x1x5qe8USzr9v.Fdphs9z7bJXNpOIwUSZdp6OuCA-1753586775-1.0.1.1-h8xOHpPRIHHwCZOsqTRatlA2PlLIXCdAZehhZAXP_jzic107gTByFAbm.hG14jwR1vUr30NsT55i5huqA26vpEWcnK7AF0qTvuKcn1OOAzs
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	namecheap.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	Sun Jul 27 03:56:15 UTC 2025 (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

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

All cookies are secure

Great. All observed cookies are marked secure.

HTML 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.

Encryption of Embedded Resources

In this section we look at the transport 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

Encryption of 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

URL from which this policy was obtained.Location

https://www.namecheap.com/

Analysis

No parent protection

This host could benefit from further protection if the apex hostname would be configured with a HSTS policy that uses 'includeSubDomains'. Enabling HSTS on an entire domain name is the only approach that provides robust security.

HSTS Policy Apex host

URL from which this policy was obtained.Location	https://namecheap.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	16,000,000 seconds (about 6 months 4 days)
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

Policy is valid

OK. Your HSTS policy uses correct syntax.

Long policy age

Your HSTS policy has a long max-age value, which offers better protection.

No subdomains

This HSTS policy doesn't cover subdomains. Without full coverage, HSTS can't protect from certain cookie attacks that typically allow active network attackers to inject cookies into an application. Additionally, subdomain coverage is one of the requirements to allow preloading.

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.

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://namecheap.com

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

Expected redirection: https://namecheap.com

Analysis

Deploy HSTS on this host

This host doesn't use HSTS, which means that its users can be easily attacked via MITM attacks. Consider deploying HSTS to disable certificate warnings and increase content and cookie security.

Policy set on plaintext port

HSTS policies must not be transmitted over insecure channels.

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

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

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

Header information

Name: x-frame-options

Value: SAMEORIGIN

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.

Feature not applicable, not implemented, or disabled

Your server doesn't support this feature.

Analysis

Explicitly disable browser XSS protection

For best security, every web site should explicitly disable browser-based XSS protection. This is because this type of functionality can be used to introduce vulnerabilities into otherwise error-free web sites.

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.

Analysis

Header information

Name: x-content-type-options

Value: nosniff

Valid configuration

Good. Your configuration is valid. This means that browsers won't try to guess file MIME type on this web site.
