Info
6/7 pass

The DMARC record allows relaxed identifier alignment for DKIM or SPF.

Info

Certificate Binding (DANE)
No MX host TLSA zone is protected by DNSSEC
None of the MX hosts have DNSSEC on their TLSA lookup zones. DANE SMTP cannot function without DNSSEC, as sending servers will ignore TLSA records from unsigned zones.
Critical
Transport Policy (MTA-STS)
Learn how it works
Info
1/6 pass
Transport Policy (MTA-STS)
MTA-STS DNS record is missing
The domain does not publish an MTA-STS TXT record, so sending servers cannot discover or enforce an MTA-STS policy.
High
TLS Reporting (TLS-RPT)

Info
1/4 pass
TLS Reporting (TLS-RPT)
No TLS-RPT record found
The domain does not publish a TLS-RPT record. Sending servers cannot report TLS errors to this domain.

DNS Integrity (DNSSEC)
DNSSEC is not enabled
The parent zone does not publish a DS record for this domain.

SOA serial does not use the recommended format
The SOA record is otherwise valid, but the serial number does not follow the recommended YYYYMMDDnn date format.

CAA and Certificate Issuance Surface
Learn how it works
Info
1/6 pass
CAA and Certificate Issuance Surface
No CAA record is published
The domain does not publish a CAA record, so any publicly trusted certificate authority may issue certificates for it after standard validation.

Info

TLS Configuration
Cipher suites without forward secrecy accepted
The server accepts one or more cipher suites using static RSA or static (EC)DH key exchange. If the server's private key is ever compromised, an attacker with recorded traffic can decrypt past sessions negotiated with these cipher suites.

Disclosure Policy (security.txt)
Learn how it works
Info
3/4 pass
Disclosure Policy (security.txt)
Expires is set more than one year in the future
The Expires date is valid and in the future, but RFC 9116 recommends keeping the expiry within one year to avoid the file becoming stale.
Low
HTTP Security Headers
Learn how it works
Info
2/7 pass
HTTP Security Headers
HSTS is not enforced
The site does not send a usable Strict-Transport-Security header, so browsers do not automatically upgrade future requests to HTTPS.
High
HTTP Security Headers
Content-Security-Policy is not enforced
The site does not send an enforced Content-Security-Policy header, leaving no restriction on script execution, framing, or resource loading beyond what other headers provide.
High
HTTP Security Headers
MIME sniffing is not disabled
The site does not send X-Content-Type-Options: nosniff, so browsers may MIME-sniff a response and interpret it as a different, potentially executable content type.
High
HTTP Security Headers
Referrer-Policy is not declared
The site does not send a Referrer-Policy header. Modern browsers default to a reasonably safe behavior, but the site does not explicitly guarantee it.
Medium
HTTP Security Headers
Permissions-Policy is missing or ineffective
The site either does not send a Permissions-Policy header, or the header only lists directives with a wildcard allowlist that does not restrict anything.
