Quick Wins
High-impact, low-effort fixes, ranked by what this scan actually found.
- Submit the password form over POST — The password stops appearing in URLs, server logs and browser history.
- Add alt text to the images that are missing it — Search engines can index the images and screen-reader users learn what they show.
- Send a Strict-Transport-Security header — Browsers refuse to fall back to plain HTTP for this domain.
- Make og:image an absolute URL — The preview image is actually fetched when the link is shared.
- Give every button an accessible name — Every control announces what it does instead of being read out as a button.
- Set font-display: swap on the web fonts — Text is readable in a fallback face from the first paint instead of being hidden.
What the site checks found
- Low — Security — No /.well-known/security.txt — anyone who finds a vulnerability has to guess where to report it.
- 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.
- Medium — Performance — 1 of 14 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 — 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.
