# Airgap Networks Inc. (Acquired by Zscaler)

> Airgap Networks was a Santa Clara-based cybersecurity company that built an agentless Zero Trust segmentation platform to stop ransomware and lateral threat movement across enterprise IT, IoT, and OT networks. Using a patented DHCP-proxy architecture, it placed every device in a 'network of one' (a /32 segment) without agents, APIs, or infrastructure upgrades, and shipped an industry-first Ransomware Kill Switch. Founded in 2019 by Ritesh Agrawal and Satish Mohan, the company raised $18.6M before being acquired by Zscaler in April 2024 to extend Zscaler's Zero Trust SASE platform with firewall-free, east-west segmentation.

- **Ransomware Kill Switch** — An industry-first one-click control that instantly disables non-essential device-to-device communication to halt ransomware's lateral spread without taking the business offline.
- **Zero Trust Firewall (ZTF)** — An agentless firewall and isolation layer that enforces dynamic, context-aware access policies and prevents threat propagation across IT/IoT/OT environments.
- **Device Discovery & Classification** — Automatic, agentless discovery, inventory, and classification of managed and unmanaged IoT/OT devices on any branch, campus, or factory network.
