Cymphony, an Israeli cybersecurity startup that tracks what employees and AI agents can access inside a company, has raised a $25m Series A round, CTech by Calcalist reported on 9 September 2026.
Sequoia Capital and SMBC Fin Atlas Beyond Fund co-led the round. Sequoia also led Cymphony's $5m seed round, and the new money brings the company's total funding to $30m. No valuation was disclosed.
Law firm Sidley Austin, which advised the company, described the financing as a $30m Series A in its own announcement. CTech's report separates the $25m Series A from the earlier $5m seed.

What Cymphony does
Cymphony's platform places a company's employees and its AI agents in one graph, together with their identities, permissions, data and behaviour. Security teams use it to see who and what can reach sensitive information, rank the resulting risks and either receive recommended fixes or have them applied automatically. Where people need to act, the system contacts the relevant employees, follows up and coordinates the remaining work.
Chief executive Shy Dekel told CTech that the company was first built to secure employees, because the largest risks in an organisation come from employee access. He said large numbers of AI tools and agents had since joined the workforce and opened big gaps, which pushed Cymphony to cover them as well.
Sidley described Cymphony as an AI governance and security platform.
The team and customers
Cymphony was founded about two years ago by Dekel, chief product officer Idan Berkovits and chief technology officer Edi Gotlieb, according to CTech. All three are graduates of the Israeli military's Talpiot programme and met during their service. Dekel spent nearly six years in Unit 8200, where he became head of its cyber department. Berkovits managed a research group in the Prime Minister's Office, and Gotlieb, an electrical engineer, worked at Apple before holding technology roles at Israel's Ministry of Defense.
The company employs about 23 people across Israel and the US, CTech reported. It said Cymphony already earns seven-figure revenue from platform sales, with customers including Syngenta, KKR, Cass Information Systems and Athennian. One large paying customer replaced two established products with Cymphony's platform.
What the money is for
Cymphony plans to use the funding to speed up product development, grow its engineering and go-to-market teams and expand sales. Dekel is moving to the US to open an office there, according to CTech.
Dekel told the publication that the company raised the money to sell significantly more, and that it had built a full infrastructure product rather than a single feature.
