+Originally created in [Flant](https://flant.com/) for internal needs & used for years, then updated to be more modern and [publicly released](https://medium.com/flant-com/introducing-ovpn-admin-a-web-interface-to-manage-openvpn-users-d81705ad8f23) in March'21. Please note that the project is currently on pause, no new Issues or PRs are accepted.
 
 ***DISCLAIMER!** This project was created for experienced users (system administrators) and private (e.g., protected by network policies) environments only. Thus, it is not implemented with security in mind (e.g., it doesn't strictly check all parameters passed by users, etc.). It also relies heavily on files and fails if required files aren't available.*
