What the site checks found

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 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.
Medium — SEO — Both www.rentalheat.by and the canonical host serve the site with HTTP 200 — the whole site exists at two addresses.
Medium — Performance — 4 of 4 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.
Medium — Infrastructure — The domain registration expires in 45 days.
Low — Infrastructure — The domain publishes no MX records, so it cannot receive email.
Low — Privacy — The site loads Google Analytics, Google Ads, Yandex Metrica with no consent layer anywhere in the markup — under the GDPR and the ePrivacy Directive those tags need consent before they run.
