- 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.
- Add a favicon — The site gets its own icon in tabs, bookmarks and history.
- 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 — SEO — No robots.txt — crawlers get no guidance and no sitemap pointer.
- 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.coenzyme.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: x-powered-by: PHP/8.2.35, PleskLin.
- 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 — Images — Images that do not load: 4 of 7 checked — the pages show a broken picture where they were.
- Low — Infrastructure — The icon the pages declare answers HTTP 404, so tabs and bookmarks fall back to a blank page symbol.
- Medium — Links — Internal links leading to an error page: 2 of 4 checked.
- Medium — Privacy — None of the scanned pages links a privacy policy (missing: privacy, terms, imprint).
