Detailed external checks

The evidence behind the rating. 41 checks across 7 categories, 6 currently failing. Failed checks are listed first.

Email

  • 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.

  • 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.

  • Strict SPF filtering - not using ~all

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

  • SPF ptr mechanism not used

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

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.

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.

  • 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.

  • Hostname matches SSL certificate

  • 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 public certificate key length

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

Data leakage

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)
