Quick Wins
High-impact, low-effort fixes, ranked by what this scan actually found.
- Turn off TLS 1.0 and 1.1 — Only protocol versions that are still safe to speak are accepted.
- Publish a CAA record — Only the certificate authority you name can issue certificates for the domain.
- Sign the zone with DNSSEC — A forged DNS answer for the domain can be detected and rejected.
What the site checks found
- Medium — Security — The server still accepts TLS 1.0 and TLS 1.1, withdrawn by RFC 8996 and refused by every browser.
- Low — Security — No CAA record — any certificate authority may issue a certificate for this domain.
- Low — Security — The zone is not signed with DNSSEC, so a forged DNS answer cannot be detected.
- Low — Infrastructure — Requests from outside a browser are answered by Cloudflare rather than by the site, so the pages and files in this report were read in a real browser and the checks that cannot be asked that way are reported as not checked.
