Israeli Cybersecurity Firm Cymphony Raises $25 Million for AI Agent Security
Cybersecurity company Cymphony has secured $25 million in Series A funding, co-led by Sequoia Capital and Fin Capital. This follows a previous $5 million seed round led by Sequoia Capital. The company, which currently employs around 23 people in Israel and the US, was founded two years ago by former Talpiot program graduates.
CEO and co-founder Shi Dekel, who previously led the cyber department at Unit 8200, explained that the company initially focused on employee access security, identifying it as a major attack surface. "We mapped identities and permissions together and knew what each employee was allowed to do," Dekel stated. The integration of AI tools and agents created significant new security gaps, prompting Cymphony to develop a unique solution.
Dekel highlighted a large public sector client where their platform replaced two leading products and prevented a data exposure incident. He noted that their ability to connect identities, information, and behavior in a single graph is unique, and AI agents have made these security problems urgent. The company has already achieved seven-figure revenues from its platform sales.
The new funding will be used to significantly scale sales, with Dekel relocating to the US to establish an office and focus on securing a strong base of large clients. "This is the time to double our capabilities," Dekel said, emphasizing his goal for Cymphony to be a product-driven company rather than just a feature provider.
Cymphony's platform addresses the evolving security landscape where AI agents, acting on behalf of employees, gain access to sensitive systems and data. The platform continuously maps employees and AI agents, creating a graph that links them to systems, permissions, and data. This allows security teams to understand not only who has access but also what data can be reached, how it's used, and the business context. The company reports that its platform is already in use by enterprise clients including Syngenta, KKR, and Cass Information Systems.
