At the same time, services are difficult to install and are compatible with a limited number of operating systems. The main feature — the ability to automatically reconnect to the network when the connection is broken (for example, in a subway tunnel). Another advantage — high data transfer rate. Among the disadvantages — limited number of compatible operating systems and installation complexity;

PPTP

A popular and at the same time the most unreliable protocol. It has a high connection speed and an extremely low level of security. It has been proven that the US NSA has encryption keys on it.

WireGuard

Combines the reliability of OpenVPN with the high speed of IKEv2. latest generation protocol. It is open source.

SSTP

Protocol for running on Windows. It is Microsoft's own development. It is fast and easy to set up, but difficult to install on other operating systems. Easy to set up, fast work. Minus — complexity of installation on other operating systems;
