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 a Strict-Transport-Security header — Browsers refuse to fall back to plain HTTP for this domain.
- Give every button an accessible name — Every control announces what it does instead of being read out as a button.
- 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.
What the site checks found
- Low — SEO — robots.txt has no Sitemap: line — crawlers have to guess where the sitemap is.
- Low — SEO — No entry in the sitemap carries a lastmod date, so crawlers cannot tell which pages have changed since they last read them.
- Low — SEO — 3 canonical addresses named by crawled pages are not listed in the sitemap: /nastolnye-svetilniki, /napolnye-svetilniki-torsher, /modulnaya-sistema-24v.
- Medium — SEO — Both www.crystallux.by and the canonical host serve the site with HTTP 200 — the whole site exists at two addresses.
- Low — Performance — The HTML is sent with no Cache-Control, Expires, ETag or Last-Modified — every visit re-downloads it in full.
- Medium — Performance — 18 of 18 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.
- 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/1.14.1, 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.
