Priority fixes for ebilet.pl

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

1. Priority 1 · Harden

   HSTS kept for at least a year

   Observed: Strict-Transport-Security was sent with a max-age of 182 days, below the one-year benchmark.

   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.

   42% of Events & Online Ticketing peers do this. Limit: Read from the homepage response only; other pages or regions may send different headers.

2. Priority 2 · Enable

   Social preview image set

3. Priority 3 · Harden

   Content Security Policy present

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

   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.

4. Priority 4 · Harden

   Certificate lifetime of 100 days or less

   Observed: The certificate from DigiCert Inc had a 198-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.
