ZenMate provides pretty basic security protocols and features. It uses industry-standard protocols like IKEv2/IPSec and OpenVPN (TCP/UDP). Also, a state-of-art protocol like WireGuard is offered by the service provider. ZenMate protects your data with unhackable AES-256 encryption and comes with the essential kill-switch feature. The VPN doesn’t leak any DNS, IPv6, and WebRTC data that could compromise your safety. With advanced features, the VPN doesn’t provide any extra privacy-enhancing features except Ad-blocker.
While you can enjoy the most secure OpenVPN protocol on both Windows and Android by default, Mac and IOS devices are limited to the IKEv2 protocol. If you are an Apple user, you must manually set up to use OpenVPN or WireGuard protocol. Moreover, WireGuard is accessible on Android only.
