Quick Wins
High-impact, low-effort fixes, ranked by what this scan actually found.
- Send a Strict-Transport-Security header — Browsers refuse to fall back to plain HTTP for this domain.
- Send an X-Frame-Options header — The site cannot be framed for click-jacking.
- Send a Referrer-Policy header — Internal URLs stop leaking to third-party sites.
- Label every form field — Fields become usable with a screen reader and clickable by their label.
- Make every id on the page unique — Anchors, labels and scripts reach the element they were pointing at.
- Give every iframe a title — Screen-reader users hear what each embedded frame contains.
What the site checks found
- Low — Performance — Redirects before the entry page is served: 2.
- 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 — The Content-Security-Policy allows 'unsafe-inline' or 'unsafe-eval', which is what a script injection needs.
- Low — Security — The Content-Security-Policy sets no frame-ancestors, so those are left at the browser default.
- 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 — SEO — 7 hreflang links are not confirmed by a link back from the other language: /de/ → /de/index.html (de), /de/ → /en/index.html (en), /de/ → /fr/index.html (fr). Google ignores one-way pairs.
