This versatility makes OpenVPN the 協議 of choice in censored environments.
OpenVPN also offers 功能s that newer 協議s lack, including certificate-based authentication, LDAP and Active Directory integration, and granular 存取 控制 lists. For enterprise 部署ments that require complex authentication and authorization, OpenVPN provides the 基礎架構 to implement your exact 安全 policy.
