Point your domain at PQ-Proxy. Every connection is automatically protected with X25519MLKEM768 — the hybrid post-quantum key exchange standardized for TLS 1.3. Your backend doesn't change.
PQ-Proxy sits in front of your existing backend. It terminates post-quantum TLS from the client, then forwards the request to your backend over a standard connection.
x-forwarded-for.
PQ-Proxy obtains and renews Let's Encrypt certificates automatically per domain.
Sign up at proxy.fipsign.dev. Add your domain and point it to the backend you want to protect. PQ-Proxy supports any backend — cloud, on-premise, serverless, or Cloudflare Workers.
Point your domain's A record to PQ-Proxy's IP. Disable the Cloudflare proxy if your domain is on Cloudflare — TLS must terminate at PQ-Proxy, not at Cloudflare.
PQ-Proxy automatically provisions a Let's Encrypt certificate for your domain and starts accepting post-quantum TLS connections. Your backend receives normal HTTP/HTTPS requests — no changes required.
