What the site checks found

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/1.26.3.
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 compressed with gzip but not with Brotli, which every current browser accepts and which is typically 15–20% smaller.
Low — Privacy — The site loads Google Analytics, Yandex Metrica with no consent layer anywhere in the markup — under the GDPR and the ePrivacy Directive those tags need consent before they run.
