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.

REVIEW

0/4 IPs match cert SAN

PTR lookup failed for 104.18.42.27: lookup 104.18.42.27: 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.

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

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

Crawlability

no robots.txt, no sitemap

REVIEW

no robots.txt, no sitemap

No robots.txt found

robots.txt is optional but recommended. It tells search engine crawlers which pages to index.

No sitemap.xml found

A sitemap helps search engines discover and index your pages more efficiently.

robots.txt is optional but recommended. It tells search engine crawlers which pages to index.

Why this matters

No robots.txt — crawlers fetch /robots.txt and get 404; not breaking but means default crawl behavior with no directives or sitemap reference.

Learn more ▾

A minimal robots.txt with `User-agent: * / Allow: / / Sitemap: https://example.com/sitemap.xml` covers the basics. Without it, crawlers behave fine but lose the sitemap signal and can't be selectively blocked from crawl-traps.

A sitemap helps search engines discover and index your pages more efficiently.

Why this matters

No sitemap.xml — Google relies on crawl-graph discovery alone, slowing indexing of deep or fresh URLs.

Learn more ▾

A sitemap accelerates Google's discovery of new and updated content. Most CMSes auto-generate one; static-site frameworks need a build-step plugin. Reference it from robots.txt and submit in Search Console to confirm Google can fetch it.

No robots.txt found

This is fine for most sites — a missing robots.txt allows all crawling by default.

CDN Cache Observability

No CDN cache-status headers in the response

REVIEW

No CDN cache-status headers in the response

Without an X-Cache / CF-Cache-Status / X-Vercel-Cache / Age header, you can't tell from outside whether a request hit the cache or went to origin. Operationally important: enables debugging stale-content reports and verifying cache rules. Most managed CDN platforms emit at least one of these by default; absence often means the platform's diagnostic headers are stripped at an upstream proxy.

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.

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.
