What the site checks found
- Medium — Security — The TLS certificate expires in 20 days.
- 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.
- 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.
- Medium — SEO — Both www.ddo.by and the canonical host serve the site with HTTP 200 — the whole site exists at two addresses.
- Medium — Performance — 1 of 16 static files checked are cached for less than a week, or not at all — returning visitors download them again.
- Medium — Performance — 1 scripts or stylesheets are sent without gzip or Brotli compression.
- Low — Performance — The HTML is compressed with gzip but not with Brotli, which every current browser accepts and which is typically 15–20% smaller.
- Medium — Performance — 3 of the images sampled are over half a megabyte: /upload/CPremier/918/xb89ww3kwe6rhcqsstch2evbi6liu1uc.svg (816 KB), /upload/resize_cache/iblock/4e2/r4fqiw19f3r8uyc27c84a60hk77gk90c/1080_10000_0/Vysokiy-banner.png (1163 KB), /upload/iblock/a93/xaxon3gorcnsgqnomd4qlw9rsbivexsw/VREMYA-BLISTAT.png (739 KB).
- Medium — Images — Images that do not load: 2 of 8 checked — the pages show a broken picture where they were.
