Techniques for uninterrupted virtual private network (VPN) connection service with dynamic policy enforcement are provided. An existing VPN session between a VPN client and a VPN server detects a change in a VPN network being used for the existing VPN session. New credentials and new policies are received by the VPN client. The new credentials are automatically used to re-authenticate the VPN client to the change during the existing VPN session, and the new policies are dynamically used to enforce the new policies during the existing VPN session on the VPN client.
