Zero Networks is an Israeli cybersecurity company that automates network microsegmentation to eliminate lateral movement by attackers after initial network compromise. Founded in 2019, the company's agentless platform deploys without installing software on endpoints—instead, it passively observes each asset's legitimate connection patterns over a two-week learning period, then automatically builds and enforces precise network access policies that block all ports and protocols outside each device's verified communication patterns. This machine-driven approach removes the manual firewall rule-writing that has historically made microsegmentation impractical at enterprise scale. The platform covers both east-west traffic between servers and north-south traffic between users and servers, protecting on-premises, cloud, and hybrid environments. Zero Networks supports multi-factor authentication enforcement at the network layer as an additional control, making it one of the few vendors that combines automated segmentation with identity-based access controls. In June 2025, the company raised $55 million in Series C funding led by Highland Europe, with participation from F2 Venture Capital, PICO Venture Partners, Venrock, and U.S. Venture Partners, bringing total capital raised to over $100 million. Highland Europe Principal Jacob Bernstein joined Zero Networks' board of directors. The company reported 300% revenue growth since its Series B and serves customers in North America, Europe, and APAC, with plans to grow its 120-person team and expand international sales.
