Domain Alignment (DMARC)
Learn how it works
Info
2/7 pass
Domain Alignment (DMARC)
DMARC policy is monitoring only
The DMARC policy uses p=none and does not ask receivers to block or quarantine failing mail.
High
Domain Alignment (DMARC)
DMARC subdomain policy is weak
Subdomains are not protected by an enforcement policy.
High
Domain Alignment (DMARC)
DMARC aggregate reporting is not configured
The DMARC record does not request aggregate reports, which reduces visibility into authentication failures.
Medium
Domain Alignment (DMARC)
DMARC alignment is relaxed
The DMARC record allows relaxed identifier alignment for DKIM or SPF.

Transport Encryption (SMTP TLS)

Info
4/5 pass
Transport Encryption (SMTP TLS)
Some MX hosts do not offer STARTTLS
At least one MX host does not advertise STARTTLS. Mail delivered through those hosts may travel in cleartext.
High
Certificate Binding (DANE)
Learn how it works
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)
Learn how it works
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
0/7 pass
DNS Integrity (DNSSEC)
DNSSEC is not enabled
The parent zone does not publish a DS record for this domain.
Medium
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.

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
