Quick Wins
High-impact, low-effort fixes, ranked by what this scan actually found.
- Mute the autoplaying media or give it controls — Nothing starts making noise the visitor cannot stop.
- Load the first image eagerly — The largest image starts downloading with the page instead of after it.
- 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.
- Link the dead-end pages to the rest of the site — Visitors and crawlers who land on the page can go on to the rest of the site.
What the site checks found
- Medium — Security — The server sends no intermediate certificate, so clients that have not cached it refuse the connection.
- Low — Security — The Content-Security-Policy is report-only — violations are logged but nothing is blocked.
- Low — Security — Response headers publish exact software versions: server: nginx/1.31.8.
- 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 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.
