 - Простой в использовании — введите IP-адрес, SSH-логин и пароль, и Amnezia автоматически установит VPN-контейнеры Docker на ваш сервер и подключится к VPN.
 - Классические VPN-протоколы: OpenVPN, WireGuard и IKEv2.
-- Протоколы с маскировкой трафика (обфускацией): OpenVPN с плагином [Cloak](https://github.com/cbeuw/Cloak), Shadowsocks (OpenVPN over Shadowsocks), [AmneziaWG](https://docs.amnezia.org/documentation/amnezia-wg/) и XRay.

 - Поддержка Split Tunneling — добавляйте любые сайты или приложения в список, чтобы включить VPN только для них.
 - Поддерживает платформы: Windows, macOS, Linux, Android, iOS.
