Quick Wins
High-impact, low-effort fixes, ranked by what this scan actually found.
- Send a Strict-Transport-Security header — Browsers refuse to fall back to plain HTTP for this domain.
- 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.
- Give every iframe a title — Screen-reader users hear what each embedded frame contains.
- Preconnect to the origins the page loads assets from — The DNS, TCP and TLS work for the other origins happens while the HTML is still parsing.
What the site checks found
- Low — Performance — The HTML is sent with no Cache-Control, Expires, ETag or Last-Modified — every visit re-downloads it in full.
- 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/1.30.6.
- 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.
- 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.
- Medium — Privacy — None of the scanned pages links a privacy policy (missing: privacy, terms, imprint).
