Priority fixes for primor.eu

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

1. Priority 1 · Harden

   Content Security Policy present

   Observed: The homepage response did not include a Content-Security-Policy header.

   Why it matters: A CSP limits where scripts, styles and frames can load from, which reduces the impact of injected or compromised third-party code.

   What to do: Start with Content-Security-Policy-Report-Only to see what would break, tighten the policy over a few weeks, then enforce it.

   48% of E-Commerce & Marketplaces peers do this. Limit: Read from the homepage response only; other pages or regions may send different headers.

2. Priority 2 · Accelerate

   HTTP/3 advertised

   Observed: The homepage did not advertise HTTP/3 through an Alt-Svc header.

   What to do: Turn on HTTP/3 at your CDN. Browsers fall back to HTTP/2 automatically, so the risk is low.

   47% of E-Commerce & Marketplaces 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.

4. Priority 4 · Enable

   Social preview image set

   Observed: The homepage had no og:image, so shared links may show without a preview image.

   What to do: Add Open Graph tags, including og:image with a 1200 x 630 image.

   60% of E-Commerce & Marketplaces peers do this.
