A VPN protocol is the set of rules a VPN uses to authenticate, negotiate keys, and encrypt your traffic inside a tunnel. Protocol choice affects speed, stability, battery use, and how well your VPN works on different networks. WireGuard is often fastest and most efficient; OpenVPN is highly compatible and configurable; IKEv2/IPsec is excellent for mobile reconnection; older options like L2TP/IPsec exist mainly for legacy compatibility. Marketing often focuses on encryption labels, but protocol implementation details matter more: modern cipher suites, secure key exchange, perfect forward secrecy, and correct DNS handling. If you care about performance, pick WireGuard and choose an exit close to you. If you need to get through strict networks, try OpenVPN with TCP/443 and obfuscation if available. Whatever protocol you choose, verify leak protection and enable a kill switch for consistent privacy.
