DNSSEC
Unsigned (DNSSEC not deployed)
REVIEW
Unsigned (DNSSEC not deployed)
Info::
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).
B
Reverse DNS
0/4 IPs match cert SAN
REVIEW
0/4 IPs match cert SAN
Info::
PTR for 3.171.198.106 does not match any cert SAN: server-3-171-198-106.sin2.r.cloudfront.net
Common when behind a CDN or shared hosting (PTR points at the provider's hostname). Mismatch can also affect mail deliverability if this IP sends email -- many MTAs reject mail when forward+reverse DNS disagree.
Info::
PTR for 3.171.198.76 does not match any cert SAN: server-3-171-198-76.sin2.r.cloudfront.net
Common when behind a CDN or shared hosting (PTR points at the provider's hostname). Mismatch can also affect mail deliverability if this IP sends email -- many MTAs reject mail when forward+reverse DNS disagree.
Info::
PTR for 3.171.198.43 does not match any cert SAN: server-3-171-198-43.sin2.r.cloudfront.net
Common when behind a CDN or shared hosting (PTR points at the provider's hostname). Mismatch can also affect mail deliverability if this IP sends email -- many MTAs reject mail when forward+reverse DNS disagree.
Info::
PTR for 3.171.198.15 does not match any cert SAN: server-3-171-198-15.sin2.r.cloudfront.net
Common when behind a CDN or shared hosting (PTR points at the provider's hostname). Mismatch can also affect mail deliverability if this IP sends email -- many MTAs reject mail when forward+reverse DNS disagree.

IPv6 Readiness

No IPv6 support
REVIEW
No IPv6 support
Info::
No IPv6 (AAAA) records found
IPv6 support is increasingly important for global accessibility. About 40% of internet users have IPv6 connectivity.
No IPv6 Support
About 40% of internet users have IPv6. Consider adding AAAA records.

IPv6 support is increasingly important for global accessibility. About 40% of internet users have IPv6 connectivity.

Why this matters

No AAAA records — same impact as 'no IPv6 (AAAA) records'; IPv6-preferring clients pay extra latency falling back to IPv4.

B
Operational Status Page
No status page link detected
REVIEW
No status page link detected
Info::
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.
B
Health Check Endpoint
No conventional health endpoint found
REVIEW
No conventional health endpoint found
Info::
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.

Add a 'Sitemap:' directive to robots.txt so search engines can discover your sitemap.

Why this matters

robots.txt omits Sitemap: directive — crawlers must fetch /sitemap.xml by convention; reliable but missing the explicit hint.

DNSSEC protects against DNS spoofing attacks. While not required, enabling DNSSEC adds an additional layer of security. Contact your DNS provider to enable it.

Why this matters

Without DNSSEC, an attacker who can poison your DNS can hijack your domain — and SSL certs alone don't stop them.

DNSSEC adds cryptographic signatures to DNS records, preventing forged responses from poisoning resolver caches. Without it, an attacker who controls the network path can redirect your domain to a malicious server before any HTTPS handshake happens. Most modern registrars (Cloudflare, Google Domains, Route 53) enable it with one toggle.

The domain can be transferred without an unlock step. Enable registrar lock (clientTransferProhibited) in your registrar's control panel to protect against unauthorized or accidental transfers.

Why this matters

Without registrar lock, an attacker who phishes your registrar credentials can transfer the domain in minutes — total brand hijack.

Learn more

Registrar lock (clientTransferProhibited, clientUpdateProhibited, clientDeleteProhibited) requires extra verification before any transfer/update/delete. Every major registrar offers it free. Combined with 2FA on your registrar account, it's the strongest defense against domain hijacking.
