Enterprise grade security


Enterprise authentication and accounting

The OpenConnect VPN server is designed for privacy, protecting the clients from accessing each others data using strict isolation and privilege separation. It secures the VPN channels using only standard protocols like TLS and Datagram TLS and prevents the leakage of cryptographic keys with Hardware Security Modules (HSMs). Public clouds today provide access to immense processing power by high-end CPUs as well as low-power and low-cost CPUs. Ocserv is designed to take advantage of that, and its performance and ability to serve clients scales linearly with number of CPUs. It has very low memory footprint to ensure that limited in memory and thus cheaper hosts can provide the necessary resources to handle thousands of clients. The server's authentication module can operate using a simple password file, to authentication methods that integrate with your organization's setup, such as Radius, OpenID Connect, Kerberos, smart cards and combinations of them to enable two-factor authentication. It further enables you to obtain detailed accounting reports using Radius.
