SSHepherd by FullArmor is a Zero Trust-based technology designed to eliminate open, listening ports for SSH, RDP, and other applications like databases while maintaining full access and functionality. It removes the attack surface for these protocols without using port knocking, packet filtering, or acting as an SSH proxy. SSHepherd deploys on both physical and virtual machines, on-premise or in the cloud, hiding servers from active scanning and providing secure user-to-server connections.
