What is IKEv2?
IKEv2/IPsec is a VPN protocol: IKEv2 sets up a secure, authenticated connection and IPsec encrypts the traffic. It's built into iPhone, Mac, Android and Windows, and it reconnects quickly when you switch between Wi‑Fi and mobile data. Privalune uses it on every platform.
IKEv2 in one paragraph
IKEv2 stands for Internet Key Exchange version 2. It's the part of a VPN connection that proves both sides are who they say they are and agrees on encryption keys. The traffic itself is then protected by IPsec. Together they're usually called IKEv2/IPsec. The protocol is an open standard published by the IETF.
Why we chose IKEv2
- Built into your device. iPhone, iPad, Mac, Android (11 and newer) and Windows all support IKEv2 in the operating system. Privalune uses that built-in support instead of a custom driver.
- Stays connected when you move. An extension called MOBIKE lets the connection survive a switch from Wi‑Fi to mobile data without starting over.
- Fast. It sets up quickly and handles everyday traffic efficiently.
- Well studied. It's been an open standard for years and is widely used by businesses.
IKEv2 compared with other protocols
| Protocol | Built into phones and PCs | Good on the move | Notes |
|---|---|---|---|
| IKEv2/IPsec | Yes | Yes | Open standard, quick reconnection |
| WireGuard | Through apps | Yes | Modern and fast, newer |
| OpenVPN | Through apps | Fair | Mature and flexible, heavier |
How to see it on your device
On iPhone, open Settings, then General, then VPN & Device Management, then VPN. Privalune appears there as an IKEv2 configuration. On Mac, it's under System Settings, VPN.
