DNSSEC

Unsigned (DNSSEC not deployed)

REVIEW

Unsigned (DNSSEC not deployed)

DNSSEC is not deployed

The zone is not DNSSEC-signed. Users on validating resolvers (Cloudflare 1.1.1.1, Quad9 9.9.9.9, growing default in mobile resolvers) get no protection against DNS spoofing for this domain. Most registrars now offer DNSSEC at a single click; consider enabling it for sites where authenticity matters (banking, healthcare, government).

CAA Records

No CAA records (any CA may issue certificates)

REVIEW

No CAA records (any CA may issue certificates)

No CAA records published

Without CAA records, any publicly-trusted CA can issue certificates for this domain. Adding a CAA record (`yourdomain. IN CAA 0 issue "letsencrypt.org"`) restricts issuance to CAs you authorize. Required by CAB Forum baseline since 2017; the default of 'any CA' is widely supported but is the broader attack surface for issuance fraud.

Reverse DNS

REVIEW

0/4 IPs match cert SAN

PTR lookup failed for 104.16.230.132: lookup 104.16.230.132: no such host

No reverse DNS record set for this IP. Common on bare cloud-VM IPs without provider-side PTR; not a security issue.

PTR lookup failed for 104.16.231.132: lookup 104.16.231.132: no such host

No reverse DNS record set for this IP. Common on bare cloud-VM IPs without provider-side PTR; not a security issue.

PTR lookup failed for 2606:4700::6810:e784: lookup 2606:4700::6810:e784: no such host

No reverse DNS record set for this IP. Common on bare cloud-VM IPs without provider-side PTR; not a security issue.

Recommended actions

Enable HSTS: Strict-Transport-Security: max-age=31536000; includeSubDomains
Enable DNSSEC on your domain for DNS spoofing protection
Enable OCSP stapling on your TLS server to remove a CA roundtrip and protect user privacy

Operational Status Page

No status page link detected

REVIEW

No status page link detected

No operational status page link detected

Status pages communicate planned maintenance and incidents to users -- a hallmark of operationally-mature services. Most SaaS teams publish one via Atlassian Statuspage, Instatus, BetterUptime, or a self-hosted Cachet. Smaller sites legitimately don't need one; flagged as Info, not a failure.

Health Check Endpoint

No conventional health endpoint found

REVIEW

No conventional health endpoint found

Health endpoints (/health, /healthz, /status, /ping, /api/health) let uptime monitors, load balancers, and orchestration systems (Kubernetes, ECS, Fly.io) verify the service is alive. Marketing sites and small services often skip them legitimately; flagged as Info, not a failure. Probe results: /api/health: 404, /health: 404, /healthz: 404, /ping: 404, /status: 404.

DNS Records

PASS

2 A records, 30 ms lookup

No NS records found

No MX records — email not configured via DNS

No SPF record found in TXT records

SPF helps prevent email spoofing. Add a TXT record starting with 'v=spf1'.

SPF helps prevent email spoofing. Add a TXT record starting with 'v=spf1'.

Why this matters

Without SPF, receiving servers can't validate sending IPs — your domain is easier to spoof in phishing.

Learn more ▾

SPF complements DMARC. Both should be published. SPF records list authorized sending IPs (e.g., `v=spf1 include:_spf.google.com ~all` for Google Workspace). After publishing, verify in Google Postmaster Tools or mxtoolbox.
