Priority fixes for taniaksiazka.pl
Ordered by impact and by how common each practice is among peers.
Priority 1 · Accelerate
HTTP/3 advertised
Observed: The homepage did not advertise HTTP/3 through an Alt-Svc header.
Why it matters: HTTP/3 runs over QUIC, which copes better with lossy mobile networks and recovers faster when a connection changes.
What to do: Turn on HTTP/3 at your CDN. Browsers fall back to HTTP/2 automatically, so the risk is low.
On Cloudflare: Enable HTTP/3 (with QUIC) under Speed > Optimization > Protocol Optimization.
47% of E-Commerce & Marketplaces peers do this. Limit: Read from the homepage response only; other pages or regions may send different headers.
Priority 2 · Harden
CAA records limit who can issue certificates
Observed: No CAA record was found for taniaksiazka.pl, 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.
On Cloudflare: Cloudflare documents which CAs its managed certificates need; include them in your CAA records.
16% of E-Commerce & Marketplaces peers do this.
Priority 3 · Harden
security.txt published
Observed: No valid /.well-known/security.txt with a Contact field was returned.
What to do: Publish /.well-known/security.txt with at least Contact and Expires fields, as RFC 9116 requires, and review it before it expires.
On Cloudflare: Cloudflare Security Center can serve a security.txt file for the zone.
7.6% of E-Commerce & Marketplaces peers do this.
Priority 4 · Harden
DNSSEC signed
Observed: No DS record was found for taniaksiazka.pl at its parent zone, so its DNS answers are not DNSSEC-signed.
What to do: Enable DNSSEC at your DNS provider, then add the DS record at your registrar. Plan provider moves carefully: a stale DS record can make the domain fail to resolve.
On Cloudflare: Enable DNSSEC in DNS > Settings and add the DS record at the registrar.
7.7% of E-Commerce & Marketplaces peers do this.
