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 Enterprise allows secure multi-platform network access, supporting Mac, Windows, and Linux. It offers robust security with encryption and multi-factor authentication but requires Linux server experience for setup. While open source and cost-effective, it lacks ease-of-use features like a configuration wizard. Users report stable but infrequent connectivity issues. Easily integrated with various platforms, it supports remote work but needs enhancements in high availability deployment, centralized management, and protocol support.
