Priority fixes for cardinfo.ir

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.

   62% of Banking & Finance peers do this. Limit: Read from the homepage response only; other pages or regions may send different headers.

2. Priority 2 · Harden

   DMARC policy enforces quarantine or reject

   Observed: No DMARC record was found at _dmarc.cardinfo.ir.

   What to do: Publish DMARC with p=none and a reporting address first, fix any legitimate senders that fail SPF or DKIM alignment, then move to quarantine and finally reject.

   70% of Banking & Finance peers do this.

3. Priority 3 · Accelerate

   Modern image formats in use

   Observed: The homepage had 17 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.

   37% of Banking & Finance peers do this.

4. Priority 4 · Enable

   Canonical URL declared

   What to do: Add a self-referencing canonical link to every indexable page, using the final https:// URL.
