Compare VPN Protocols – PPTP vs L2TP vs OpenVPN

There are variety of protocol options, each with unique capabilities and strengths. Consider what protocols your devices support, what trade-off between security and speed makes sense for you, and whether any protocols are blocked by your network.

PPTP L2TP/IPsec OpenVPN
VPN Encryption 128-bit 256-bit 256-bit
VPN Security Basic encryption Highest encryption. Checks data integrity and encapsulates the data twice. Highest encryption. Authenticates data with digital certificates.
VPN Speed Fast due to lower encryption. Requires more CPU processing to encapsulate data twice. Best performing protocol. Fast speeds, even on connections with high latency and across great distances.
Stability Works well on most Wi-Fi hotspots, very stable. Stable on NAT-supported devices. Most reliable and stable, even behind wireless routers, on non-reliable networks, and on Wi-Fi hotspots.
Compatibility Native in most desktop, mobile device and tablet operating systems. Native in most desktop, mobile device and tablet operating systems. Supported by most desktop computer operating systems and Android mobile and tablet devices.
Remarks PPTP is a fast, easy-to-use protocol. It is a good choice if OpenVPN isn’t supported by your device. L2TP/IPsec is a good choice if OpenVPN isn’t supported by your device and security is top priority. OpenVPN is the recommended protocol for desktops including Windows, Mac OS X and Linux. Highest performance – fast, secure and reliable.
