Chameleon is VyprVPN’s proprietary protocol designed to bypass censorship and VPN blocking. It obfuscates OpenVPN packet metadata, making it unrecognizable to deep packet inspection (DPI), while retaining high speed and strong 256-bit encryption. This allows Chameleon to overcome restrictions in heavily censored countries (China, Russia, Turkey, Iran, etc.) and to solve throttling or blocking issues from ISPs. Additionally, Smart IP technology periodically changes the server’s IP address, making detection and blocking much harder.

OpenVPN is an open-source VPN protocol known for its reliability, strong security, and ability to bypass firewalls. It uses SSL/TLS for key exchange and supports both UDP and TCP.

WireGuard is a modern, high-performance VPN protocol with strong encryption. It is lightweight, easy to configure, and ideal for mobile devices due to its low overhead.

IKEv2 is a modern and secure VPN protocol known for its speed and ability to reconnect quickly after connection drops. It works well on mobile networks.

L2TP (Layer 2 Tunneling Protocol) is often paired with IPsec for encryption. It’s supported on most devices but offers slower performance compared to modern protocols.

IPsec (Internet Protocol Security) is a suite of protocols used to secure IP communications through authentication and encryption. It is commonly used with L2TP and IKEv2.
