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 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.
- Send a Permissions-Policy header — Camera, microphone and geolocation stay switched off for embedded content.
- Shorten the over-long titles — The whole title stays visible in search results.
- Redirect http:// to https:// — Visitors and crawlers land on the encrypted address every time.
What the site checks found
- Low — SEO — No entry in the sitemap carries a lastmod date, so crawlers cannot tell which pages have changed since they last read them.
- Medium — SEO — Both www.biomika.by and the canonical host serve the site with HTTP 200 — the whole site exists at two addresses.
- High — Security — http:// does not redirect to https:// — the plain-text address stays reachable.
- 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: server: nginx/1.30.6, x-powered-by: PHP/8.4.27.
- 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 — Performance — The HTML is sent with no Cache-Control, Expires, ETag or Last-Modified — every visit re-downloads it in full.
- Medium — Performance — 8 of 8 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.
