The features I have found to be most valuable are the levels of encryption I can enact and the compression I can apply to improve throughput.
OpenVPN Access Server is open source and offers strong encryption and scalability for secure connections. It supports platforms like Mac, Windows, Linux, iOS, and Android, facilitating flexible remote work. The easy setup suits small projects, though Linux expertise is needed. It enhances security with multi-factor authentication, but could improve in compatibility and advanced security features. Issues include connectivity and licensing costs. Secure connections without complex setups are key advantages.
