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 a Referrer-Policy header — Internal URLs stop leaking to third-party sites.
- Write meta descriptions for the pages without one — Google stops inventing snippets and shows the copy you wrote.
- Send a Permissions-Policy header — Camera, microphone and geolocation stay switched off for embedded content.
- Merge the SPF records into one — The SPF record starts being read instead of discarded.
What the site checks found
- Low — SEO — robots.txt has no Sitemap: line — crawlers have to guess where the sitemap is.
- Medium — SEO — No sitemap.xml found at either the conventional paths or the one robots.txt names.
- Low — Performance — The HTML is sent with no Cache-Control, Expires, ETag or Last-Modified — every visit re-downloads it in full.
- Medium — Performance — 17 of 18 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.
- 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: Microsoft-IIS/10.0, x-powered-by: PHP/7.3.1, ASP.NET.
- Medium — Security — SPF records published: 2. The standard allows exactly one, and receivers discard all of them.
- 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 — Links — Internal links that reach their page through a redirect: 1 of 1 checked.
- Low — Privacy — The site loads Google Tag Manager, Yandex Metrica with no consent layer anywhere in the markup — under the GDPR and the ePrivacy Directive those tags need consent before they run.
