Israeli Cybersecurity Firm Zero Networks Secures $55 Million

Zero Networks is shifting the balance of power in cybersecurity from attackers to defenders

Israeli cybersecurity startup Zero Networks Ltd. has secured $55 million in Series C funding to grow its team and expand global go-to-market efforts. Founded in 2019, Zero Networks provides automated microsegmentation solutions to prevent lateral movement and block ransomware attacks. The company's platform simplifies zero-trust security by learning network behavior and enforcing least-privilege access controls without manual configurations or additional agents.

In December 2023, Zero Networks highlighted the complexity and labor-intensive nature of existing segmentation solutions. Their software-as-a-service learns network traffic and creates security policies that restrict access to necessary assets, deploying multifactor authentication to stop hackers from moving laterally.

The core offering includes creating secure micro-perimeters around every device on a network and identity segmentation to prevent privileged account abuse. These features enhance security against unauthorized access and credential-based attacks.

Since its last funding round in 2023, Zero Networks has tripled its customer base and achieved over 300% revenue growth. Notable customers include Evercore Inc., Vermeer Corp., B Riley Financial Inc., MIO Partners Inc., Greenhill & Co. Inc., and Baron Capital Group Inc.

The Series C round, led by Highland Europe Ltd., included participation from F2 Venture Capital, PICO Venture Partners LP, Venrock Associates, and U.S. Venture Partners LP. Jacob Bernstein, principal at Highland Europe, will join Zero Networks' board of directors. The latest round brings Zero Networks funding to over $100 million.

Co-founder and CEO Benny Lakunishok stated, "This funding validates that we can make segmentation simple, scalable, and powerful enough to contain ransomware and stop lateral movement."
