Zero Networks secures $55 million in Series C funding to expand its automated, agentless microsegmentation platform designed to stop lateral movement in cyberattacks. The company reports 300% revenue growth and a tripled customer base since its previous funding round. Backed by Highland Europe and other investors, the funds will support global expansion and continued product development.
Big Money, Bigger Mission: Zero Networks Lands $55M to Take on Cyber Threats
Zero Networks secures $55 million in Series C funding to strengthen its cybersecurity platform focused on stopping lateral movement. The round brings the company’s total capital raised to over $100 million. Leading the investment is Highland Europe, with support from existing investors including F2 Venture Capital, PICO Venture Partners, Venrock, and U.S. Venture Partners. Jacob Bernstein, Principal at Highland Europe, joins the company’s board of directors.
The funding supports Zero Networks’ position in what it describes as the “Era of the Defender,” where the defensive effort in cybersecurity becomes proactive. Instead of reacting to breaches, Zero Networks aims to shift the burden onto attackers by enforcing identity- and network-based controls.
Why Microsegmentation Finally Gets the Spotlight
Microsegmentation has long been considered a strong defense against lateral movement, yet widespread adoption has lagged due to its implementation complexity. Traditional methods required extensive manual configuration and were difficult to scale, limiting their effectiveness.
Zero Networks introduces a simplified, agentless solution that automates microsegmentation. Its approach uses automated asset tagging and policy creation, significantly reducing deployment time. The platform eliminates the need for extensive manual input while maintaining tight control over internal network traffic.
This change comes at a time when lateral movement remains a prevalent tactic in ransomware and supply chain attacks. Despite perimeter defenses, attackers often gain unrestricted access once inside a network. Zero Networks focuses on neutralizing this internal movement, which is frequently undetected for extended periods.
The Numbers Tell the Story: Growth That Commands Attention
Zero Networks reports a 300% increase in revenue since its Series B round. The company also tripled its customer base and doubled its workforce in the same period.
Funding will support several key initiatives:
- Expansion of sales and marketing teams
- Growth in research and development
- Enhanced customer support infrastructure
- Increased go-to-market investments in North America, EMEA, and APAC
These moves reflect a larger demand among enterprises to secure internal networks and implement real zero trust models that go beyond surface-level perimeter security.

A Product Built for the Defender, Not the Hacker
Zero Networks’ solution operates without agents and integrates with existing environments. It automates microsegmentation and ties access control to identity, allowing only verified users and devices to interact with network assets.
Its MFA-enforced platform supports Zero Trust Network Access (ZTNA) and Identity Least Privilege capabilities. These features enforce least-privilege access across users, workloads, and devices, offering consistent policy enforcement and strong internal controls.
The product’s focus is on simplicity, scalability, and operational efficiency. It enables companies to deploy controls rapidly and adjust policies in dynamic network environments without introducing unnecessary complexity.
Backed by Industry Veterans, Trusted by Enterprises
The Series C round is led by Highland Europe, whose representative Jacob Bernstein now sits on Zero Networks’ board. According to Bernstein, the customer response during due diligence stood out. He highlights strong user satisfaction across the board, citing consistent positive feedback and platform usability.
The company maintains a strong reputation among clients, supported by favorable reviews and measurable security improvements. This reflects confidence in the product’s real-world application and operational impact.
Zero Networks credits its team across all functions for contributing to its success, from founding members to recent hires.
The Next Cyber Battlefield: Lateral Movement Must End Here
Lateral movement remains a critical vector for attackers after breaching perimeter defenses. Without internal segmentation, attackers can explore and exploit systems undetected.
Zero Networks targets this vulnerability by blocking lateral pathways within networks. Its automated microsegmentation limits access at the workload level, restricting movement and reducing the blast radius of potential breaches.
This internal focus strengthens compliance performance, improves audit results, and enhances penetration test outcomes. It supports enterprise-wide efforts to adopt and maintain zero trust architectures.
What This Means for Security Teams Worldwide
The Series C funding allows Zero Networks to scale its operations and deliver more aggressive defense mechanisms globally. By enabling defenders to implement identity-based segmentation quickly, it reduces reliance on reactive security models.
Security teams benefit from a solution that simplifies policy management while maintaining control across complex environments. The ability to stop lateral movement early supports continuous compliance and helps organizations meet regulatory and security standards without excessive overhead.
With expanded resources and a growing footprint, Zero Networks sets a benchmark for microsegmentation’s role in enterprise security frameworks.
