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 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.
- Serve every asset over https:// — Browsers stop blocking assets and warning about the padlock.
- 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
- Medium — SEO — Both www.biotest.by and the canonical host serve the site with HTTP 200 — the whole site exists at two addresses.
- Medium — SEO — A URL that does not exist answers with HTTP 200 — search engines index missing pages as real ones.
- 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: x-powered-by: PHP/7.4.33.
- 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.
- High — Links — Internal links leading to an error page: 7 of 10 checked.
- 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.
- Low — Infrastructure — Requests from outside a browser are answered by bot protection rather than by the site, so the pages and files in this report were read in a real browser and the checks that cannot be asked that way are reported as not checked.
