Why VPN Protocols Matter in 2025
In 2025, network security and performance are more critical than ever. Whether you’re a remote worker using a dedicated VPN server for business, a gamer seeking low latency, or a traveler connecting through public Wi-Fi, your VPN protocol defines how data moves between your device and the server.
- WireGuard: Lightweight, modern, and designed for speed.
- OpenVPN: Battle-tested, highly configurable, and widely supported.
Protocols determine encryption methods, connection stability, and even battery usage. For instance, WireGuard can outperform traditional configurations, especially when paired with a virtual private network that is optimized for mobile devices or a VPN proxy service for iOS users.
