VPN tunneling protocols are a technology that helps VPNs securely send your data over the Internet, something that is necessary if you want to use social media, surf the web, or do almost any other online activity.
The various protocols differ in terms of speed and security. Most of them are considered obsolete and insecure, so they are rarely used - like PPTP or L2TP, which we don't offer in any of our applications.
Reliable, stable, and secure protocol with 18+ experience of open source development.
Using OpenVPN you connect to ZenMate via an encrypted TLS (Transport Layer Security) connection. Originally released in 2002 OpenVPN has become very popular and a de-facto standard, among others, because it isn't impressed by wireless access points, firewalls, NAT-based routers, and HTTP proxy servers and will bypass them without problems, can use different ports, and keeps its speed even on long-distance Internet routing. As for the security, OpenVPN is a must-have, for it provides an up to 256 bits encryption and works with the OpenSSL library of both the control channels and the data you send through - the easiest task ever.
