StreamVPN provides industry-standard security features and protocols. All the data traffic is routed through the most secure OpenVPN and IKEv2 protocols and is backed by AES-256 military-grade encryption. However, protocols vary depending on the device you use. Windows and macOS apps use the safest OpenVPN; IOS is on IKEv2, which is also pretty well. Lastly, the Android app uses L2TP, which is outdated and needs to be replaced soon.
The service also includes the vital Kill switch feature, which is essential to protect your IP address from being exposed in case the VPN connection drops. StreamVPN is also immune to any DNS, IP, or WebRTC leaks.
