Invisinet by Invisinet is a Zero Trust cybersecurity solution designed to secure critical infrastructure from edge to cloud. It focuses on cyber-attack prevention by eliminating unauthorized access to IT and OT resources. Invisinet operates at the TCP/UDP layer, implementing Transport Access Control (TAC) to authenticate user or device identity and apply security policies before establishing application sessions. The product aims to secure existing OT, IT, and cloud operations by enforcing identity-based access, microsegmenting with identity, hiding critical assets, and enabling dynamic network segmentation.
