Zero Networks Raises $55M Series C to Usher in the “Era of the Defender”

For years, cyber attackers have held a strategic advantage. Zero Networks is changing that. 

With a newly raised $55 million in Series C funding, Zero is paving the way for the Era of the Defender – a paradigm shift in cybersecurity that removes the burden from defenders reacting to threats and places it on attackers, forcing them to confront proactive, identity- and network-driven controls. 

A New Age in Cybersecurity  

Zero Networks’ Series C, led by Highland Europe with participation from F2 Venture Capital, PICO Venture Partners, Venrock, and U.S. Venture Partners, brings total funding to more than $100 million. Jacob Bernstein, Principal at Highland Europe, will join Zero’s board of directors.  

Since its Series B, Zero has: 

• Tripled our customer base  
• Doubled headcount 
• Grown revenue by more than 300%  

This growth highlights rising enterprise urgency around stopping lateral movement and enforcing true zero trust controls. The new investment will fuel:  

• Team expansion across sales, marketing, research and development, and customer support  
• Increased go-to-market investments in North America, EMEA, and APAC 
• Continued innovation in Zero Networks’ award-winning solutions 

Reclaiming Microsegmentation with Simplicity That Scales  

Lateral movement remains a defining tactic in the majority of ransomware and supply chain attacks; traditional tools focus on the perimeter, but once breached, attackers can move freely, often undetected for days or weeks.  

The solution? Microsegmentation. But while microsegmentation has long been hailed as the gold standard for stopping lateral movement, it has historically been viewed as too complex to implement and scale. 

“Microsegmentation has long been the crown jewel of network defense; praised for its effectiveness but abandoned because of its complexity,” said Benny Lakunishok, CEO and Co-Founder of Zero Networks. 

According to Jacob Bernstein, Principal at Highland Europe and newest member of Zero’s board of directors, microsegmentation’s relatively low adoption comes down to misunderstanding:

“Cybersecurity’s most promising but often misunderstood tool is microsegmentation. This technique is essential to proactive zero trust architecture that prevents attacks by design rather than merely responding to them.”  

Zero Networks challenges the long-standing notion that comprehensive network security must spell complexity by delivering an automated, agentless solution that makes microsegmentation both effective and effortless.  

For Lakunishok, Zero’s latest fundraise sends a clear message:  

“This funding raise validates everything we’ve claimed since day one: that we can make segmentation simple, scalable, and powerful enough to contain ransomware and stop lateral movement at its source. It also opens up a massive opportunity for every network defender out there to stop playing catch-up and start taking control.”
