What We Do
Zero Networks fixes the root cause of most successful cyberattacks - overly open networks and excessive logon permissions - with a simple, fully automated platform for zero trust segmentation and remote access. Zero Networks learns and automatically restricts network and user access to what's strictly essential, leveraging multi-factor authentication to stop attacks from spreading.
