Obfuscation (Stealth VPN)

Obfuscation - often called stealth VPN - aims to make VPN traffic harder to detect and block. Some networks use deep packet inspection to identify VPN protocols and throttle or block them. Obfuscation layers can wrap or transform VPN packets so they resemble normal HTTPS traffic or other common patterns, improving connectivity in restrictive workplaces, campuses, or countries. Techniques vary: proprietary obfuscation, TLS tunneling, “stunnel,” Shadowsocks-style wrappers, or OpenVPN configured to mimic web traffic over TCP/443. Obfuscation can increase latency and reduce throughput, so it’s typically used only when needed. If your main goal is speed, use WireGuard without obfuscation. If your main goal is reliability under censorship, try OpenVPN with obfuscation and a stable exit region. For DVPN users, obfuscation may be implemented in the client or through gateway nodes; the same principle holds - hide VPN signatures to keep tunnels usable in hostile networks.
