About this tool
A VPN (Virtual Private Network) protocol is the technical standard that encrypts your internet traffic and routes it through a secure tunnel. This reference tool helps you understand and compare the most common protocols—WireGuard, OpenVPN, IKEv2, L2TP, PPTP, and SSTP—so you can choose the right one for your security needs, connection speed, and device compatibility. Whether you're protecting your privacy on public Wi-Fi, accessing geo-restricted content, or securing remote work connections, knowing the strengths and weaknesses of each protocol is essential.
To use this tool, browse through each protocol's profile to see its security features, speed performance, encryption standards, ease of setup, and compatibility with different operating systems. For each protocol, you'll find details on whether it's open-source, how resistant it is to detection, typical latency overhead, and which devices (desktop, mobile, router) support it natively. This comparison format lets you quickly identify which protocol best matches your priorities—whether you value maximum security, raw speed, or ease of use across multiple platforms.
VPN protocols have different trade-offs: newer protocols like WireGuard prioritize both speed and security with modern cryptography, while older protocols like PPTP are fast but outdated and vulnerable. If you're comparing VPN providers, you'll often see them offer multiple protocol choices—this reference helps you understand what each choice means for your actual security and performance. Use this tool as a starting point for evaluating your VPN setup, then consult your VPN provider's documentation for their specific implementation details and recommendations.
