Website Security

Sentry

CSP contains unsafe-eval

The Content Security Policy is implemented with unsafe-eval, reducing protection against XSS attacks.

X-Content-Type-Options is not nosniff

Browsers may interpret files as a different MIME type than what is specified in the Content-Type HTTP header. This can lead to MIME confusion attacks.

Server information header not exposed

Ensuring the server information header is not exposed reduces the ability of attackers to exploit certain vulnerabilities.

X-Powered-By header not exposed

Information about specific technology used on the server is obscured.

CSP implemented without insecure active sources

The Content Security Policy does not allow any insecure active sources.

CSP implemented without broad sources

A Content Security Policy is implemented to help protect against XSS and clickjacking attacks.

Referrer policy is not unsafe-url

The website's Referrer Policy is not configured to allow unsafe information to be sent in the referrer header.

ASP.NET version header not exposing specific ASP.net version

Ensuring the ASP.NET version header is not exposing a specific version makes it harder for attackers to exploit certain vulnerabilities.

ASP.NET version header not exposed

Ensuring the ASP.NET version header is not exposed makes it harder for attackers to exploit certain vulnerabilities.

CSP implemented without insecure passive sources

The Content Security Policy does not allow any insecure passive (img/media) sources.

No unmaintained page detected

The page appears to be maintained.

Email

Sentry

DMARC policy is not p=none

DMARC reject policy provides the most effective protection against fraudulent emails being sent from a domain.

DMARC policy exists

DMARC protects against fraudulent emails being sent from a domain.

Strict SPF filtering - not using +all

Sender Policy Framework (SPF) record strictly enforces specific domains allowed to send email on its behalf.

SPF syntax correct

Sender Policy Framework (SPF) record passes basic syntax checks.

DMARC policy percentage is default

DMARC policy percentage is set to default 100%, ensuring all mail is covered by the policy.

SPF ptr mechanism not used

Sender Policy Framework (SPF) record does not include the ptr mechanism.

DNS

Sentry

DNSSEC not enabled

DNSSEC records prevent third parties from forging the records that guarantee a domain's identity. DNSSEC should be configured for this domain.

No unregistered MX records detected

No unregistered MX records that could lead to receiving mail on behalf of the target organization were detected.

No subdomain takeover vulnerability detected

No dangling DNS records that could lead to subdomain takeover were detected.

CAA enabled

The domain contains a valid Certification Authority Authorization (CAA) record. A CAA record indicates which Certificate Authorities (CAs) are authorized to issue certificates for a domain.

Encryption

Sentry

Weak cipher suites supported in TLS 1.2

Weak cipher suites can potentially be broken by a well resourced attacker, and should not be supported by the server unless very old devices or browsers must be supported.

Certificate not found on our revoked certificate list

The site's certificate chain was checked against our list of revoked certificates.

SSL available

SSL is supported for this site.

HTTP requests are redirected to HTTPS

All HTTP requests are redirected to HTTPS.

With HSTS enforced, people browsing this site are less susceptible to man-in-the-middle attacks.

No insecure SSL/TLS versions available

No insecure SSL/TLS versions are available for this site.

SSL certificate chain present in server response

A complete SSL certificate chain was presented by the server for this domain.

SSL chain certificates do not expire within 20 days

SSL intermediate and root certificates do not expire within 20 days.

SSL expiration period shorter than 398 days

The SSL certificate presented by the server has an expiration period shorter than 398 days.

SSL has more than 20% of its valid period remaining

SSL certificate does not expire in less than 20% of its total valid period.

Strong SSL algorithm

Industry standard SHA-256 encryption in use.

Domain is included on the HSTS preload list

Being included on the preload list gives the highest level of protection against MITM attacks for users of all major browsers.

Strong public certificate key length

The site's public certificate provides at least 112 bits of security strength.

Vulnerability Management

Sentry

Not vulnerable to CVE-2014-0160 (Heartbleed)

A bug in OpenSSL's implementation of the TLS heartbeat extension allows access to portions of memory on the targeted host e.g. cryptographic keys and passwords.
