Domain Alignment (DMARC)

Info
4/7 pass
Domain Alignment (DMARC)
DMARC policy quarantines unauthenticated mail
The DMARC policy asks receivers to treat failing mail as suspicious, but does not request full rejection.
Medium
Domain Alignment (DMARC)
DMARC subdomain policy uses quarantine
Subdomains are protected by quarantine, but failing mail is not explicitly rejected.
Medium
Domain Alignment (DMARC)
DMARC alignment is relaxed
The DMARC record allows relaxed identifier alignment for DKIM or SPF.

Info
1/5 pass
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)
Learn how it works
Info
5/7 pass
DNS Integrity (DNSSEC)
DNSSEC uses a discouraged algorithm
DNSSEC validation can succeed, but one or more algorithms or digest types are not recommended for new deployments.
Medium
DNS Integrity (DNSSEC)
NSEC3 iterations exceed the recommended value
The zone uses NSEC3 with a non-zero iterations count, which RFC 9276 recommends against due to unnecessary CPU cost for validating resolvers.

DNS Health (Delegation & Exposure)

Info
7/8 pass
DNS Health (Delegation & Exposure)
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.
Low
CAA and Certificate Issuance Surface
Learn how it works
Info
4/6 pass
CAA and Certificate Issuance Surface
Certificate issuance is not pinned
The CAA records authorize a CA but do not restrict issuance to a specific account or validation method.
Low
CAA and Certificate Issuance Surface
No S/MIME issuance policy is published
The domain does not publish an issuemail CAA property, so any CA may issue S/MIME certificates for its email addresses; note that issue and issuewild do not restrict S/MIME issuance.

TLS Configuration

Info
5/6 pass
TLS Configuration
Weak elliptic curve accepted for key exchange
The server negotiates an elliptic curve below 256 bits for at least one ECDHE cipher suite. Weak curves reduce the effective security margin of the key exchange well below modern standards.

Disclosure Policy (security.txt)
Learn how it works
Info
0/4 pass
Disclosure Policy (security.txt)
security.txt is not present or not usable
The domain does not publish a usable security.txt file. Either both /.well-known/security.txt and /security.txt returned no file (404/401/403/410), or the location responded with HTTP 200 but non-text/plain content (typically an application page) or a body that is not valid UTF-8.
Medium
HTTP Security Headers
Learn how it works
Info
1/7 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
Clickjacking protection is missing
The site does not restrict framing through CSP frame-ancestors or a usable X-Frame-Options value, so it can be embedded in a frame on any origin.
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.
Medium
