Clientless remote access is remote network access obtained without the installation of software on a user's device.
Unlike IPsec VPNs, the F5 FirePass SSL VPN provides remote access without requiring pre-installed client software and configuration of the remote device. Neither client- nor server-side application changes are required. FirePass enables the administrator to restrict or permit access based on the security state of the device being used to access the network. Based on the presence of a digital certificate upon login, FirePass can support access to a broad range of applications.
