Priority fixes for kenhub.com
Ordered by impact and by how common each practice is among peers.
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 Cloudflare: Enable HSTS under SSL/TLS > Edge Certificates > HTTP Strict Transport Security and raise max-age gradually.
34% of Education & Online Learning peers do this. Limit: Read from the homepage response only; other pages or regions may send different headers.
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.
On Cloudflare: Enable HTTP/3 (with QUIC) under Speed > Optimization > Protocol Optimization.
25% of Education & Online Learning 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.
5% of Education & Online Learning peers do this.
Priority 4 · Enable
Reachable over IPv6
Observed: No IPv6 (AAAA) address was published for www.kenhub.com.
What to do: Enable IPv6 at your CDN or host and publish the AAAA record it provides.
On Cloudflare: Cloudflare offers IPv6 compatibility for proxied hostnames; check the setting in Network.
39% of Education & Online Learning peers do this.
