Choosing a VPN is only half the equation — the protocol it uses determines your actual speed, security, and reliability. Indian users face unique challenges: variable ISP quality, government deep packet inspection, and the need for both speed and security. Understanding WireGuard, OpenVPN, and IKEv2 helps you configure your VPN for optimal performance. The wrong protocol choice can cut your speed in half or leave you vulnerable.
