Zero Networks has secured $55 million in Series C funding, positioning itself as one of the most compelling cybersecurity innovators redefining how network defense is done. The raise was led by Highland Europe, with continuing support from F2 Venture Capital, PICO Venture Partners, Venrock, and USVP—bringing the company’s total funding to over $100 million. Highland Europe’s Jacob Bernstein will take a seat on the company’s board, underscoring the firm’s commitment to what they see as not only a fast-growing company, but a paradigm-setter for the cybersecurity space.
Zero Networks has built its success around what has historically been considered the most powerful but most elusive goal in cybersecurity: microsegmentation. While industry consensus has long touted it as the most effective way to prevent lateral movement and contain breaches, most companies have avoided it due to the daunting complexity of implementation. What Zero Networks has done is eliminate that obstacle. Their agentless, automated approach has made true microsegmentation not just feasible but scalable—even across complex enterprise environments. The company’s technology allows organizations to block unauthorized lateral movement by default, shifting the attacker’s burden dramatically. The traditional model—where defenders scramble to catch up to breaches—gets inverted. Here, attackers are forced to fight through deliberate and dynamic network constraints, enforced in real time and mapped directly to identity.
That core proposition has not only resonated with security teams but translated into growth metrics that investors could hardly ignore. Since its Series B, Zero Networks has tripled its customer base, doubled its workforce, and seen a staggering 300% increase in revenue. Much of this has been driven by escalating enterprise urgency around ransomware and supply chain threats, where the lack of internal segmentation continues to be a glaring vulnerability. Attackers who bypass perimeter defenses often move laterally, exploiting trust relationships, unsegmented networks, and overlooked access rights. Zero Networks aims to nullify this pattern.
Benny Lakunishok, CEO and Co-Founder, describes the mission in clear terms: making microsegmentation simple, scalable, and effective enough to fulfill its original promise. He frames the new funding not merely as a validation of the company’s approach but as a rallying point for defenders across the world—security professionals long stuck in reactive roles, now empowered to regain initiative. Their vision doesn’t stop with segmentation. Zero Networks also offers Zero Trust Network Access (ZTNA) and Identity Least Privilege solutions, all wrapped into a single platform. Its identity-anchored, MFA-enforced approach ensures that users, devices, and workloads all operate within precise access boundaries—enabling zero trust in its truest form.
Highland Europe’s Bernstein echoes this sentiment, noting that the enthusiasm among Zero Networks’ users far surpasses the norm. What they’ve built, he says, isn’t just another cybersecurity product—it’s a solution users “love,” a rare distinction in an industry often defined by frustration and compromise. His view is that Zero Networks is uniquely equipped to translate early success into large-scale market dominance, both through product excellence and strategic team-building.
With this funding round, Zero Networks will scale up operations in sales, marketing, R&D, and customer support, while aggressively expanding into key global markets including North America, EMEA, and APAC. Their presence at Black Hat USA this August is expected to mark another milestone in their campaign to evangelize simplified microsegmentation and take their message directly to the defenders on the front lines of enterprise security.
At a moment when most companies are still reeling from post-breach containment and forensics, Zero Networks is offering an inversion of the playbook: prevent the breach from spreading at all. The strategy is elegant in its simplicity—and finally, it’s deployable.
