Quick Wins
High-impact, low-effort fixes, ranked by what this scan actually found.
- Publish a DMARC record — Forged mail from the domain starts being reported and, later, rejected.
- Answer missing pages with 404 instead of a server error — A mistyped URL gets a helpful page instead of a server error.
- Serve the icon the pages declare — Tabs, bookmarks and history get the site icon back.
- Stop publishing software versions in response headers — Attackers stop being handed the exact version to look up exploits for.
- Publish a CAA record — Only the certificate authority you name can issue certificates for the domain.
- Publish a security.txt — Whoever finds a vulnerability knows where to report it.
What the site checks found
- Medium — Infrastructure — A URL that does not exist answers with HTTP 502 instead of 404.
- Low — Infrastructure — The icon the pages declare answers HTTP 502, so tabs and bookmarks fall back to a blank page symbol.
- Low — Performance — The HTML is sent with no Cache-Control, Expires, ETag or Last-Modified — every visit re-downloads it in full.
- Low — Security — No /.well-known/security.txt — anyone who finds a vulnerability has to guess where to report it.
- Low — Security — Response headers publish exact software versions: server: nginx/1.18.0 (Ubuntu).
- Medium — Security — No DMARC record at _dmarc — nothing tells receiving servers what to do with mail that fails the SPF check.
- 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.
