Priority fixes for houseandgarden.co.uk

Ordered by impact and by how common each practice is among peers.

1. Priority 1 · Harden

   HSTS kept for at least a year

   Observed: The homepage response did not include a Strict-Transport-Security header.

   Why it matters: HSTS tells browsers to use HTTPS for your host on every later visit, which removes the window where a first HTTP request can be intercepted.

   What to do: Send Strict-Transport-Security on HTTPS responses. Start with a short max-age (for example 300 seconds), confirm every subdomain works over HTTPS, then raise it in steps to 31536000. Add includeSubDomains only when all subdomains are HTTPS. HSTS preload is optional and hard to undo; hstspreload.org itself does not recommend it by default.

   On Amazon CloudFront: Attach a response headers policy with Strict-Transport-Security to each distribution.

   27% of Online Publishing peers do this. Limit: Read from the homepage response only; other pages or regions may send different headers.

2. Priority 2 · Accelerate

   Modern image formats in use

   Observed: The homepage had 69 images and none used WebP or AVIF.

   What to do: Serve WebP or AVIF with a JPEG or PNG fallback, either through an image CDN or by generating both formats at build time.

   38% of Online Publishing peers do this.

3. Priority 3 · Harden

   Certificate lifetime of 100 days or less

   Observed: The certificate from Amazon had a 394-day validity period, longer than the 100-day maximum that applies from March 2027.

   What to do: Move to automated issuance and renewal now, while you still have time to test it.

   71% of Online Publishing peers do this.

4. Priority 4 · Harden

   CAA records limit who can issue certificates

   Observed: No CAA record was found for houseandgarden.co.uk, so any public certificate authority may issue for it.

   What to do: Publish CAA records naming every CA you actually use, including the CAs your CDN uses for managed certificates. Add an iodef contact if you want reports.

   12% of Online Publishing peers do this.
