clay.com Security Report — Grade C- (70/100)

Q: Does clay.com have DMARC configured?

Yes. clay.com's DMARC policy is set to 'none'. SPF record: yes. Strengths: DMARC pct=100 — policy applies to all mail; Aggregate reports (rua) configured; Forensic reports (ruf) configured; SPF soft-fail (~all) configured; SPF DNS lookup count: 2/10 (within limit); DKIM configured (selectors: google, resend). Issues: DMARC policy is 'none' (monitoring only, no enforcement).

Q: Does clay.com use HSTS?

No. Strict-Transport-Security header is missing. Connections can be downgraded to HTTP via man-in-the-middle attacks. If this domain is in the browser HSTS preload list, browsers may still enforce HTTPS — but the header should be present for full coverage.

Q: Does clay.com have DNSSEC enabled?

No. Strengths: 4 nameservers configured (ns-906.awsdns-49.net, ns-1996.awsdns-57.co.uk, ns-245.awsdns-30.com, ns-1398.awsdns-46.org); NS records span 4 providers (awsdns-49.net, co.uk, awsdns-30.com, awsdns-46.org) — genuine redundancy; SOA record present and MNAME consistent with NS set; 5 MX record(s) present; Zone transfers properly restricted on all nameservers; Address records present: 4 A record(s). Issues: DNSSEC not configured — DNS responses can be spoofed or tampered with in transit (DNS cache poisoning).

Finish setting up email authentication

DMARC / Email Security

2–4 hours High

Spoofed emails can still reach your customers and partners until this is fully enforced. Email authentication for clay.com is partly set up, but there are gaps: your DMARC policy is set to monitor-only, so nothing actually gets blocked yet. Until it's fully in place, someone could still send a convincing fake email pretending to be you.

NIST SP 800-177r1§4

Trustworthy Email recommends SPF, DKIM and DMARC for every email domain

How to fix this

1Change your DMARC policy from "none" to "quarantine" in your DNS settings (you're using Google Workspace — see https://knowledge.workspace.google.com/admin/security/set-up-dkim) — this moves suspicious mail to spam instead of just watching it happen. Your current record with just that change:

v=DMARC1; p=quarantine; rua=mailto:[email protected]; ruf=mailto:[email protected]

2Double-check it's live: search "dmarc record checker" and enter clay.com.

Blocking Issues

Not enabled

Strict-Transport-Security header is missing. Connections can be downgraded to HTTP via man-in-the-middle attacks. If this domain is in the browser HSTS preload list, browsers may still enforce HTTPS — but the header should be present for full coverage.

Likelihood: ★★★☆☆

Impact: ★★★★☆

2/5 present

Missing: X-Content-Type-Options, Referrer-Policy, Permissions-Policy

Likelihood: ★★★☆☆

High Priority

p=none

Strengths: DMARC pct=100 — policy applies to all mail; Aggregate reports (rua) configured; Forensic reports (ruf) configured; SPF soft-fail (~all) configured; SPF DNS lookup count: 2/10 (within limit); DKIM configured (selectors: google, resend). Issues: DMARC policy is 'none' (monitoring only, no enforcement).

Likelihood: ★★★☆☆

Impact: ★★★☆☆

Medium Priority

Warn

Issues: No MTA-STS configured — email in transit is vulnerable to TLS downgrade attacks; sending servers cannot verify your mail server requires TLS; No TLSRPT record (_smtp._tls) — TLS delivery failures won't be reported to the domain owner.

Likelihood: ★★☆☆☆

Impact: ★★★☆☆

Not enabled

Strengths: 4 nameservers configured (ns-906.awsdns-49.net, ns-1996.awsdns-57.co.uk, ns-245.awsdns-30.com, ns-1398.awsdns-46.org); NS records span 4 providers (awsdns-49.net, co.uk, awsdns-30.com, awsdns-46.org) — genuine redundancy; SOA record present and MNAME consistent with NS set; 5 MX record(s) present; Zone transfers properly restricted on all nameservers; Address records present: 4 A record(s). Issues: DNSSEC not configured — DNS responses can be spoofed or tampered with in transit (DNS cache poisoning).

Likelihood: ★★☆☆☆

Impact: ★★★☆☆

Best Practice

Warn

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

Likelihood: ★☆☆☆☆
