Israeli cybersecurity company Silverfort, which is valued at over $1 billion, is buying another Israeli startup called Fabrix. Fabrix focuses on using artificial intelligence to protect digital identities.
The exact price of the deal hasn’t been shared, but it is believed to be worth tens of millions of dollars. After the acquisition, all 14 employees from Fabrix will become part of Silverfort.
After the acquisition, the companies plan to create a system that can quickly decide what each user or identity—whether it’s a person, a machine, or an AI—can access within an organization in real time.
This is not the first time Silverfort has bought another company. So far, it has raised more than $222 million, including $116 million in 2024. The company has around 600 employees worldwide, with about half based in Israel. In November 2024, it also bought an Israeli cloud security company called Rezonate.
By acquiring Fabrix, Silverfort wants to improve its platform. The goal is to better handle complex decisions about who or what can access systems in real time—especially when it comes to machines, non-human identities, and AI agents.
“Today, Identity Security and access control rely on rules that are created at ‘admin time’, attempting to pre-define access. But in the AI era, it’s becoming impossible to keep up, and organizations are rapidly losing control. The only way to mitigate this risk without stopping the business is to make access decisions at runtime, using AI and deep context,” said Hed Kovetz, CEO and Co-Founder of Silverfort. “Together with Fabrix, Silverfort’s platform will empower enterprises to protect their human, non-human, and agentic identities and their access, dynamically and continuously, using a runtime AI decisioning engine. Fabrix’s innovative technology and track record across AI, security and identity bring the expertise needed to create the new standard for Identity Security in the AI era.”
“We founded Fabrix with a clear vision: making Identity Security easier, faster, and more scalable using an AI-native approach,” said Raz Rotenberg, CEO and Co-Founder of Fabrix. “By joining Silverfort, we can bring this transformation to the largest companies in the world and combine our AI engine with Silverfort’s runtime enforcement to create something no one has achieved before. We are excited to become part of the team shaping the future of identity security.”
Fabrix was started in 2025 by CEO Raz Rotenberg and CTO Ofir Yakovian. Raz was one of the first engineers at Run: ai, a company later bought by Nvidia. Ofir previously worked as a tech lead at Orca Security and Microsoft Entra, and he has a master’s degree in quantum computing.
The company’s VP of R&D, Roee Oz, earlier worked as a chief architect for Microsoft Defender for Cloud and led AI security projects at Microsoft. Fabrix raised $8 million in early funding from investors like Norwest, toDay Ventures, Jibe Ventures, and also from founders and executives from major companies such as Google, Palo Alto Networks, Microsoft, and Nvidia.
