Zero Networks is a cybersecurity company founded in 2019 and headquartered in Tel Aviv, Israel. It is led by Benny Lakunishok (CEO) and Amir Frankel (CTO). The company specializes in zero trust identity and network security solutions, particularly focusing on preventing attackers from moving laterally within corporate networks to steal data or launch ransomware attacks. Zero Networks offers a fully automated SaaS platform that dynamically learns network traffic and creates granular security policies to restrict user and machine access to strictly necessary resources only.

The platform uses an agentless approach to microsegmentation, dynamically creating secure micro-perimeters around every device on a network, including operational technology and Internet of Things devices. This ensures least-privilege access control and reduces risks of unauthorized access. It also enforces multifactor authentication for access to sensitive protocols, which are often targeted by attackers to move laterally inside networks.

Zero Networks aims to simplify the complex and labor-intensive existing segmentation solutions by automating policy creation and enforcement. Their solution also provides identity segmentation to limit admin and service account access based strictly on operational needs, enforcing just-in-time access and multifactor authentication to prevent privileged account abuse.

Since its founding, the company has achieved rapid growth and funding milestones, including raising $20 million in Series B funding in 2023 and subsequently $55 million in 2025, supporting expansion of its development, marketing, and sales teams to scale globally. It is recognized for delivering comprehensive protection against credential-based and ransomware attacks through a scalable zero trust security model.
