Israeli AI Security Firm Symphoni Raises $30 Million

Israeli cybersecurity startup Symphoni has secured $30 million in funding to develop and expand its platform designed to address the growing security challenges posed by AI agents in the workplace. The funding round includes $25 million in Series A financing led by Sequoia Capital and Fin Capital, following a previous $5 million seed round also led by Sequoia.

Founded approximately two years ago by three graduates of the elite Talpiot program, Symphoni currently employs around 23 people in Israel and the United States. The company's founders are CEO Shi Dekel, Product Manager Idan Berkovitch, and CTO Adi Gottlieb. Dekel previously led the cyber department at Unit 8200, Berkovitch was a research group manager in the Prime Minister's Office, and Gottlieb worked at Apple and in Israeli defense technology roles.

The core problem Symphoni addresses is the security risk associated with AI agents acting on behalf of employees, potentially accessing sensitive information and systems using employee credentials. The platform maps connections between identities, AI agents, and the organizational data and systems they can access. Its goal is to provide security teams with visibility into what information employees and AI agents can actually access and what they do with it, going beyond formal permission lists.

Symphoni's system aggregates data from cloud software, AI tools, identity management systems, and other sources to prioritize risks and recommend remediation actions. It can automate fixes or escalate issues to human teams. The company reports that its platform has already uncovered instances where sensitive data, such as salary and bonus information, was accessible to a broader group of employees than intended, a vulnerability that AI agents could exploit.

The company's platform is already in use by major organizations including investment firm KKR, agrochemical company Syngenta, and Cass Information Systems. The new funding will be used for further product development, expanding engineering and sales teams, and increasing operations in the U.S. and other markets. Sequoia Capital partner Bogomil Balkansky noted that companies providing visibility and control over AI agent activity could become essential organizational software infrastructure.
