Zero Networks Secures $55M to Advance Microsegmentation Platform

Zero Networks has raised $55 million in Series C funding to accelerate its global expansion and product development in the zero-trust security space, according to SiliconANGLE. The Israeli cybersecurity firm plans to grow its team and scale go-to-market operations as organizations increasingly adopt microsegmentation strategies to counter lateral movement and ransomware threats.

Founded in 2019, Zero Networks offers an automated, agentless microsegmentation platform that dynamically learns network behavior and applies least-privilege access controls. By removing the need for manual configuration or endpoint agents, the solution aims to simplify zero-trust implementation for enterprises. The platform also integrates multifactor authentication for sensitive access points, strengthening defenses against lateral attacks.

In addition to segmenting network devices, the company’s platform supports identity segmentation—restricting access privileges for admin and service accounts to operational needs only. This layer of control helps mitigate the risk of credential misuse and privilege escalation, especially in hybrid or complex IT environments where traditional controls fall short.

The funding round, led by Highland Europe with participation from existing backers, brings Zero Networks' total funding to over $100 million. The company reports significant growth since its last round, including a tripled customer base and 300% revenue increase. New board representation from Highland Europe is expected to support its next phase of scaling.
