Priority fixes for expressvpn.com
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 Amazon CloudFront: Select HTTP/3 in the distribution's supported HTTP versions.
57% of VPNs peers do this. Limit: Read from the homepage response only; other pages or regions may send different headers.
Priority 2 · 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.
52% of VPNs peers do this.

Priority 3 · Harden
Certificate lifetime of 100 days or less
Observed: The certificate from Amazon had a 197-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.
81% of VPNs peers do this.
Priority 4 · Enable
Reachable over IPv6
Observed: No IPv6 (AAAA) address was published for www.expressvpn.com.
What to do: Enable IPv6 at your CDN or host and publish the AAAA record it provides.
57% of VPNs peers do this.
