VLESS Reality is the current state of the art for stealth VPN protocols. Instead of negotiating a fake TLS handshake (the old VLESS XTLS-Vision approach), Reality terminates a real TLS session with a real upstream website — Google, Microsoft, whatever you choose — and only your own client knows that a tunnel is hidden inside.
For deep packet inspection systems, that means: no JA3 signature mismatch, no certificate oddities, no traffic shape that says "this is a VPN". The censor sees a TLS session to a common destination and lets it pass.
When does Reality stop being enough? When the upstream site is itself censored, or when the censor begins blocking based on flow-level fingerprints (packet timing, payload size distributions). VenvVPN exposes Reality as a first-class protocol on every node so you can pin a clean upstream per region.
