| Security | Strong (modern crypto) | Strong (robust) |
| Compatibility | Limited on older devices | Broad (widely supported) |
| Ease of Setup | Simple | Moderate |
Choose based on your needs: WireGuard for speed, IKEv2 for reliability.
IKEv2/IPsec: The Mobile Maverick
IKEv2/IPsec isn't exactly new—it's been around since 2005—but recent trends are refining it for today's mobile-centric world. As smartphones and tablets dominate internet use, this protocol shines in handling frequent disconnections, like when switching from Wi-Fi to cellular.
Imagine driving through a tunnel and losing signal. IKEv2/IPsec reconnects instantly, without dropping your session. That's crucial for travelers or commuters using VPNs on the go. Combined with IPsec's encryption, it offers top-notch security against eavesdropping.
