ACT Security is a stealth-mode cybersecurity startup headquartered in Tel Aviv, Israel, established in 2025. The company was founded by the entrepreneurial team behind Medigate, which was acquired by Claroty in 2021 for approximately $400 million. The founders include Jonathan Langer, who serves as the lead, Itay Kirshenbaum as Chief Technology Officer, Stephen Goldberg as Chief Product Officer, and Ilai Fallach. Their previous venture, Medigate, developed a specialized cybersecurity platform for medical devices and the Internet of Medical Things (IoMT).
The new venture, currently known as ACT, secured $20 million in a seed funding round from notable investors including Team8 and the U.S. venture capital firm Bessemer Venture Partners. The company is operating in the cloud security market, aiming to provide a more advanced layer of protection that moves beyond traditional visibility and vulnerability disclosure. The core of its business model is to develop a platform that enables security teams to take concrete and effective actions to mitigate and reduce risks within their cloud infrastructures.
