Quick Wins
High-impact, low-effort fixes, ranked by what this scan actually found.
- Give every form a submit control — Visitors can actually send the form.
- Send X-Content-Type-Options: nosniff — Browsers stop guessing content types and executing files as scripts.
- 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.
- Point the aria-* attributes at ids that exist — The controls announce the name the markup was already trying to give them.
- Fix the invalid markup the HTML parser rejects — Browsers stop having to guess how the broken markup was meant to nest.
What the site checks found
- Low — SEO — Sitemap URLs pointing at a different domain: 1 — they will be ignored.
- Medium — SEO — 1 canonical links point at an address that redirects: /data-center/data-center/ (301) — point them at the final URL.
- Low — Security — Strict-Transport-Security is set but its max-age is under six months.
- Low — Security — The Content-Security-Policy sets no default-src, object-src, base-uri, 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 — Performance — 1 of 18 static files checked are cached for less than a week, or not at all — returning visitors download them again.
