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.
|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.|
