Access control that exposes network services only while a user is authenticated.

Knocknoc ties network reachability to identity: services stay dark until a user authenticates, then open only to that user for the duration of their session. It gives teams just-in-time exposure control in front of VPNs, admin panels, and internal services. The Australian company was founded in 2022.
