Its Zero Trust Exchange platform connects users, devices, and applications directly and securely over the internet - inspecting traffic in the cloud rather than backhauling it through legacy hardware appliances. Founded in 2007 and publicly traded on NASDAQ as ZS, Zscaler processes hundreds of billions of transactions daily for thousands of large organizations, and has expanded into AI-driven security operations, data protection, and digital experience monitoring.
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.
