Elisity’s Bet: Make the Switches You Already Own Stop the Next Breach
Hospitals and factories have thousands of devices they cannot patch, reboot or even name. Elisity’s answer is to identify them, limit where they can talk and make the existing network do the enforcing.
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.
Ritesh Agrawal
Ritesh Agrawal is a network-security engineer turned founder who co-founded Airgap Networks in 2019 to attack the problem most enterprises ignore: lateral movement once an attacker is already inside the building. His bet was that you do not trust any device, period. Zscaler acquired Airgap in April 2024, and its agentless, identity-based microsegmentation became the foundation of Zscaler's Zero Trust Branch, which Ritesh now leads as VP of Product Management. Before founding the company he spent nearly 18 years at Juniper Networks across engineering, product, and sales.
Illumio
Illumio is a Sunnyvale-based cybersecurity company that pioneered Zero Trust Segmentation. Its Breach Containment Platform - Illumio Segmentation plus the AI-powered Illumio Insights - assumes attackers will get in and focuses on stopping them from spreading. By mapping how applications talk to each other across data centers, public clouds, and endpoints, Illumio lets organizations isolate workloads and contain ransomware and breaches before they become disasters.
