VPN protocols and encryption, explained
IPVanish supports WireGuard, OpenVPN, and IKEv2. This page explains the general trade-offs in plain terms.
WireGuard
A newer, leaner protocol generally known for faster connection speeds, particularly noticeable on mobile devices.
OpenVPN
An older, highly configurable protocol, often favored for compatibility with restrictive networks and firewalls.
IKEv2
A protocol known for stability when switching networks, such as moving from Wi-Fi to mobile data.
AES-256 Encryption
A widely used, strong encryption standard applied across supported protocols to help protect tunnel traffic.
Scramble / Obfuscation
Some configurations support obfuscating VPN traffic to make it less identifiable on restrictive networks.
Double Hop
Routing traffic through two VPN servers in sequence for an additional layer of separation between you and the destination.
General guidance for choosing a protocol
Start with WireGuard
For most everyday use, WireGuard tends to offer the best balance of speed and simplicity.
Try IKEv2 on mobile if connections feel unstable
IKEv2 is often a good fit for devices that frequently switch between Wi-Fi and mobile data.
Switch to OpenVPN if a network seems to block VPN traffic
OpenVPN's configurability can help on restrictive networks.
Test after changing settings
After switching protocols, reconnect and confirm the connection is stable before relying on it.
Protocols & Encryption FAQ
Is WireGuard less secure than OpenVPN?
Not inherently. WireGuard uses modern, well-regarded cryptography; the two protocols differ more in configurability and network compatibility than in fundamental security.
Why would I choose IKEv2?
IKEv2 is often favored on mobile devices for its ability to reconnect quickly when switching between networks, such as Wi-Fi and mobile data.
Does changing protocols require reinstalling the app?
No. Protocol selection is typically a setting within the VPN app itself, changeable without reinstalling anything.
