Detailed external checks

The evidence behind the rating. 57 checks across 7 categories, 9 currently failing. Failed checks are listed first.

Website Security

  • 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.

  • 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.

  • No unmaintained page detected

    The page appears to be maintained.

Email

  • DMARC policy not found

    DMARC policy was not found. This makes it easier for attackers to send email from this domain. A DMARC policy should be deployed for this domain.

  • SPF policy uses ~all

    Sender Policy Framework (SPF) record is too lenient as to which domains are allowed to send email on the domain's behalf. This record should preferably not use the ~all mechanism, as this does not instruct the mail receiver to reject messages from unauthorised sources. When DMARC is not being enforced, -all should be used on the SPF record.

  • SPF ptr mechanism used

    Sender Policy Framework (SPF) record contains the ptr mechanism. This mechanism is intended to be used temporarily to check that a domain resolves to itself via a known IP address. This should not be used permanently as it puts unnecessary burden on DNS servers and some mail checkers may drop the SPF record if this mechanism is found.

  • SPF enabled

    Sender Policy Framework (SPF) records prevent spammers from sending messages with forged addresses.

  • SPF syntax correct

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

Network

  • 'HTTP' port open

    The 'HTTP' service is running and exposed to the internet. The configuration of the server should be reviewed and unnecessary ports closed.

DNS

  • 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.

  • CAA not enabled

    The domain does not contain a valid Certification Authority Authorization (CAA) record. A CAA record indicates which Certificate Authorities (CAs) are authorized to issue certificates for a domain.

  • No unregistered MX records detected

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

  • Domain has not expired

    Domain has not expired.

  • Domain does not expire soon

    Domain does not expire within 30 days.

  • Domain not flagged as inactive

    Domain is not flagged as inactive.

  • Domain not pending deletion

    Domain is not pending deletion with the registrar.

  • Domain not pending restoration

    Domain is not pending restoration with the registrar.

  • Domain registrar or registry deletion protection enabled

    Domain is protected from unsolicited deletion requests with the registrar or registry.

  • Domain registrar or registry transfer protection enabled

    Domain is protected from unsolicited transfer requests.

  • Domain registrar or registry update protection enabled

    Domain is protected from unsolicited update requests with the registrar or registry.

  • Domain free of registrar DNS resolution hold

    Domain is not under a DNS resolution hold with the registrar.

  • Domain free of registry DNS resolution hold

    Domain is not under a DNS resolution hold with the registry itself.

  • Domain renewal not prohibited by registry

    Domain is not prohibited from renewal at the registry itself.

Encryption

  • HTTP Strict Transport Security (HSTS) not enforced

    Without HSTS enforced, people browsing this site are more susceptible to man-in-the-middle attacks. The server should be configured to support HSTS.

  • HTTPS redirect not supported

    HTTPS is the standard protocol for secure communication on the internet. All redirects should be performed over HTTPS.

  • 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.

  • Hostname matches SSL certificate

    The site's hostname matches the SSL certificate.

  • SSL has not expired

    SSL certificate has not expired.

  • Trusted SSL certificate

    The certificate presented by this domain was issued by a trusted certificate authority.

  • 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.

  • Strong Diffie-Hellman prime used in key exchange

    TLS connections to the site use a strong Diffie-Hellman prime during key exchange.

  • Strong public certificate key length

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

IP/Domain Reputation

  • No reports of botnet activity in the last 30 days

    This IP/domain has not been reported as a source of botnet activity in the last 30 days.

  • No reports of brute force login attempts in the last 30 days

Vulnerability Management

  • 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.

  • Not vulnerable to CVE-2014-3566 (POODLE)

    The server does not support SSLv3, and is not vulnerable to the POODLE attack.

  • Not vulnerable to CVE-2015-0204 (FREAK)

    The server does not offer RSA_EXPORT cipher suites, so clients are not vulnerable to the FREAK attack.

  • Not vulnerable to CVE-2015-4000 (Logjam)

    The server is using strong Diffie-Hellman parameters and is not vulnerable to the Logjam attack.
