Protocol Comparison Criteria
Security
Encryption strength, authentication methods, vulnerability history, and security audits.
Performance
Connection speed, latency, CPU usage, and throughput capabilities.
Compatibility
Platform support, client availability, and configuration flexibility.
Reliability
Connection stability, reconnection speed, and network traversal.
Choosing the Right Protocol
- security For Maximum Security: Choose OpenVPN or WireGuard
- speed For Speed: Choose WireGuard for best performance
- devices For Mobile: Choose IKEv2 for native support
- public For Firewalls: Choose OpenVPN or SSTP
Encryption Technologies
Modern Ciphers
AES-256-GCM, ChaCha20-Poly1305 - Strong, efficient, widely supported
Legacy Ciphers
AES-256-CBC, Blowfish - Less efficient, potential vulnerabilities
Key Exchange
ECDHE, Curve25519 - Forward secrecy, quantum-resistant options
Security Notice:
- • PPTP has known vulnerabilities and should be avoided
- • Always use strong encryption (AES-256 or better)
- • Consider quantum-resistant cryptography for long-term security
- • Keep VPN clients and servers updated
history VPN Protocol Evolution
PPTP - First VPN Protocol
Introduced by Microsoft, now considered insecure
L2TP/IPsec - Layer 2 Tunneling Protocol
Combination of L2TP and IPsec for enhanced security
OpenVPN - Open Source Protocol
Highly configurable, secure, widely adopted
SSTP - Microsoft's Solution
Designed to work through restrictive firewalls
WireGuard - Modern Protocol
Lightweight, fast, simplified codebase
