Quick Wins
High-impact, low-effort fixes, ranked by what this scan actually found.
- Send a Referrer-Policy header — Internal URLs stop leaking to third-party sites.
- Make every id on the page unique — Anchors, labels and scripts reach the element they were pointing at.
- Send a Permissions-Policy header — Camera, microphone and geolocation stay switched off for embedded content.
- Make the menu button a real, focusable button — Keyboard and switch users can open the navigation.
- Enable HTTP/2 — Assets download in parallel over one connection.
- Introduce a Content-Security-Policy — Injected scripts stop being able to run.
What the site checks found
- Low — Performance — The HTML is sent with no Cache-Control, Expires, ETag or Last-Modified — every visit re-downloads it in full.
- Medium — Performance — 18 of 18 static files checked are cached for less than a week, or not at all — returning visitors download them again.
- Low — Performance — The HTML is compressed with gzip but not with Brotli, which every current browser accepts and which is typically 15–20% smaller.
- Low — Security — No /.well-known/security.txt — anyone who finds a vulnerability has to guess where to report it.
- Medium — Security — No SPF record — anyone can send email that claims to come from this domain.
- 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.
- Low — Privacy — The site loads Google Analytics, Yandex Metrica with no consent layer anywhere in the markup — under the GDPR and the ePrivacy Directive those tags need consent before they run.
- Medium — Privacy — None of the scanned pages links a privacy policy (missing: privacy, terms, imprint).
