Knocknoc

Knocknoc is a novel yet elegant approach to removing attack surface. Put simply: Knocknoc links your single-sign on experience to existing network access controls. Why expose your VPNs, dev/test environments and corporate applications to anyone, anywhere, all the time? Systems are simply invisible to attack, until your users centrally log in. No client install, no VPN required, no chokepoints, use your existing infrastructure for direct and low latency access. Protect SSH bastion hosts, vulnerable VPN or edge networking devices, legacy web applications or otherwise remove 0day exposure by taking your assets off the network until your authorised users log in centrally.
