Zero Networks, a cybersecurity startup from Tel Aviv has raised $55 million in Series C funding round. They want to bring back an important but often overlooked idea in network security called micro-segmentation.
The round was led by Highland Europe with help from F2 Venture Capital, PICO Partners, Venrock and USVP. This brings the company’s total funding to more than $100 million. Jacob Bernstein from Highland Europe will also join the company’s board.
Zero Networks was founded in 2019 and has become known for making microsegmentation—a complex security method—much easier to use.
This method protects networks by separating devices and services from each other, not just guarding the outer edge of the network.
Microsegmentation was once seen as a top-level cybersecurity tool, but many companies found it too difficult to set up. Because of that, even strong networks could be at risk if hackers got past the first layer of defence.
“Microsegmentation has long been praised for its effectiveness but abandoned because of its complexity,” said CEO and co-founder Benny Lakunishok. “This funding validates everything we’ve claimed since day one: that we can make segmentation simple, scalable, and powerful enough to stop lateral movement at its source.”
This Series C funding comes at a time when more companies are looking for “zero trust” security systems. These systems don’t automatically trust anyone based on their location in the network—instead, they check each user’s identity and device before giving access.
Zero Networks is focusing on two big trends: making access control based on identity and helping businesses protect themselves from ransomware and supply chain attacks that spread easily through networks without proper segmentation.
Since its Series B funding, the company says it has tripled the number of customers, doubled its team size, and increased its revenue by over 300%. They haven’t shared exact numbers, but the growth is clear.
This shows that more companies are now looking for strong, proactive security tools that can stop attackers even after they break into a network—something that’s becoming very important for large businesses.
The company currently employs over 120 people, including around 70 in Tel Aviv.
Besides micro-segmentation, the platform also offers Zero Trust Network Access (ZTNA) and identity-based least privilege controls. This means it helps limit access to only what’s truly needed—for users, devices, and cloud systems.
Together, these features create what the company calls a “unified” zero-trust platform. It’s built not just to find security threats but to stop them from happening in the first place.
