Explanation
IPSec (Internet Protocol Security) is a suite of protocols that authenticates and encrypts IP packets, providing a secure channel between two networks - making it the foundation for many VPN implementations. L2TP (Layer 2 Tunneling Protocol) creates tunnels but provides no encryption on its own (it is often paired with IPSec for security). PPP (Point-to-Point Protocol) is a basic data link protocol without built-in strong encryption. PPTP (Point-to-Point Tunneling Protocol) is an older VPN protocol with known security vulnerabilities and is considered insecure by modern standards.
