Security checks — sorted by severity
MTA-STS & TLS Reporting
Issues: No MTA-STS configured — email in transit is vulnerable to TLS downgrade attacks. Sending servers cannot verify that your mail server requires TLS; No TLSRPT record — TLS delivery failures won't be reported to domain owner.

DNS CAA Records
No CAA records found. Without CAA, any Certificate Authority can issue certificates for this domain. Adding CAA records restricts issuance to authorized CAs only, reducing the risk of misissued certificates.

DNS Configuration
Strengths: 2 nameservers configured (brett.ns.cloudflare.com., jamie.ns.cloudflare.com.); 5 MX records present; Zone transfers properly restricted. Issues: DNSSEC not configured — DNS responses can be spoofed.

DMARC / Email Security
Strengths: SPF record present with soft-fail (~all); DKIM configured (selectors: s1, s2). Issues: DMARC policy is 'none' (monitoring only, no enforcement).

security.txt (RFC 9116)
No security.txt found. Publishing a security.txt at /.well-known/security.txt is the industry standard (RFC 9116) for vulnerability disclosure policies. Its absence may indicate a less mature security program.

MX Records & Mail Provider
Strengths: Mail handled by Google Workspace; 5 MX record(s) configured; Multiple MX records provide redundancy.

Certificate Hygiene
Strengths: Certificate valid, 63 days remaining; Issued by Google Trust Services; 64 certificates logged in CT; Certificates from 2 CAs: Google Trust Services, Let's Encrypt. Note: Wildcard certificate in use (*.domain) — covers all subdomains. Common practice; worth noting that compromise would affect all subdomains.

Recommended actions

Steps to improve xavior.ai's security grade, ranked by impact.
1
Strengthen email authentication configuration
Email authentication is partially configured for xavior.ai but has gaps. Actions needed: upgrade DMARC policy from 'none' to 'quarantine' or 'reject'. Until DMARC enforcement is active, spoofed emails may still reach recipients.
NIST CSFPR.AC-7
Email authentication is a required access control
How to fix this
1
Upgrade DMARC policy to p=quarantine (then p=reject after monitoring)
2
Verify with: nslookup -type=txt _dmarc.xavior.ai
