WireGuardⓇ is the default protocol in PIA’s iOS VPN app. It’s optimized for speed and security, making it the ideal protocol for everyday browsing and speed-intensive activities like streaming.
You can also select to use small packets in the iOS app. Our VPN will reduce the IP packet size to make your connection more compatible with different routers and mobile networks, which is useful if you and your iOS device are on the go.
IPSec (IKEv2) is reliable for speed, using the UDP socket and port 500 for reduced latency. It’s an excellent choice for gaming and streaming on iPhone/iPad, thanks to its fast connections. It also integrates well with iPhone because it has the ability to maintain connections while switching networks, such as from mobile data to public Wi-Fi.
You can select different encryption levels with IPSec (IKEv2) in the PIA VPN iOS app, and choose the handshake used to determine how your data is transmitted over the network.
OpenVPN is a flexible protocol known for its ability to overcome connection issues, which is especially important if you’re struggling to get the speeds you need on your iPhone or iPad.
You can select the TCP over UDP communication protocol for a speed boost when streaming or gaming. You can also switch back to UDP if you’re using your iOS device for something sensitive like online banking or sending files via AirDrop and need additional security. PIA VPN’s encryption is also customizable for the OpenVPN protocol.
