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
Supported and well configured
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
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
Supported and well configured
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
Supported and well configured
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
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

Name Server Configuration

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 6844) 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.
Powerup!
Policy doesn't use reporting
This policy doesn't use reporting, which means that there is no way to contact you when a violation is detected. The CAA RFC defines the iodef property that can be used for this purpose. 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
Everything seems to be well configured. Well done.

Analysis

Good
Configuration satisfies advertised MTA-STS policy
Good. This host supports MTA-STS, which means that it restricts which MX servers can be used and how they are configured. We've verified that all MX servers listed here match the policy.

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

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.
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.
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.

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.
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.
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.

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.
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.
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.

Test passed
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.

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.

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.

Platform Trusted
Apple iOS
Apple MacOS
Google AOSP
Microsoft
Mozilla

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.

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.

Excellent. Your DANE configuration matches the certificate chain(s) provided by the service. Your TLS configuration enjoys the additional benefit of DANE validation.

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.

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
2 media file(s)
  2 out of 2 are secure  View all

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.

33 link(s)
  33 out of 33 are encrypted  View all

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
Everything seems to be well configured. Well done.

HSTS Policy  Main host

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.
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: simplelogin.io; 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 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.

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

Analysis

Powerup!
Inline scripts are allowed
By default, CSP doesn't allow inline script execution, but this policy overrides that behavior by specifying 'unsafe-inline' in the 'script-src' directive. As a result, all XSS defenses provided by CSP are significantly weakened.
Powerup!
Inline styles are allowed
This policy allows inline styles. Although they are not as bad as inline scripts in terms of security, an injection bug in script area would allow the attacker to modify page appearance.
Powerup!
Dynamic code execution is allowed
By default, CSP doesn't allow dynamic script execution via eval and friends, but this policy overrides that behavior by specifyin 'unsafe-eval' in the 'script-src' directive. As a result, XSS defenses provided by CSP are significantly weakened.
Powerup!
Mixed content not blocked
This CSP policy doesn't use any of the directives designed to handle mixed content. Consider using the 'block-all-mixed-content' and 'upgrade-insecure-requests' directives as appropriate to ensure that no mixed content is allowed.
Powerup!
Form targets not restricted
The 'form-action' directive is not explicitly set. Because this directive doesn't fall back to default sources, this means that all targets are allowed.

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 response HTTP header that web sites can use to monitor problems related to their Certificate Transparency (CT) compliance. Additionally, they can also instruct browsers to reject any certificates in their name that are are not CT-compliant.

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

Expect-CT Policy

URL from which this policy was obtained.Location https://www.simplelogin.io/
Specifies policy duration. Once activated, Expect-CT stays in force
until this time lapses. Browsers update policy cache duration
every time they receive a new Expect-CT header from a site.max‑age 		604,800 seconds (about 7 days)
This optional directive controls whether CT compliance
will be enforced by your policy. It's useful if you're
confident in your configuration and wish to deploy CT
before browsers start enforcing it.enforce
This optional directive enables reporting and specifies
the endpoint clients should use to submit reports.report-uri 		https://simplelogin.report-uri.com/r/d/ct/enforce

Analysis

Info
Header information

Policy text: enforce, max-age=604800, report-uri="https://simplelogin.report-uri.com/r/d/ct/enforce"

Good
Reporting endpoint operational
Good. The reporting endpoint accepted our test submission.

Report URI: https://simplelogin.report-uri.com/r/d/ct/enforce

Good
Expect-CT enabled
Excellent. This web site has a valid Expect-CT policy.

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
Header information

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

Modern browsers ship with built-in defenses against Cross-Site Scripting (XSS), usually known as XSS Auditors. Web sites are allowed to control the defenses if they specify an X-XSS-Protection header in their HTTP responses. Recommended policies are either to block XSS attacks, or disable the defenses if you think false positives are possible. Filtering, where offending fragments of data are removed, is not recommended because it can be abused by attackers to selectively deactivate script files.

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

Analysis

Info
Header information

Name: X-XSS-Protection

Value: 1; mode=block

Good
Valid configuration
Good. Your configuration enforces blocking when XSS attacks are detected.

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

Info
Header information

Name: X-Content-Type-Options

Value: nosniff

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