WireDog uses the AmneziaWG protocol, a hardened evolution of WireGuard that adds traffic obfuscation on top of the same ChaCha20 encryption and Poly1305 authentication. Unlike standard WireGuard, AmneziaWG disguises your VPN traffic to look like ordinary QUIC/DoQ traffic on port 443, making it far harder for networks and firewalls to detect, fingerprint, or block.
