Oak emerged from stealth with $60 million in seed funding to build the security industry’s Identity Operating System. The AI-native platform will replace the fragmented stack of legacy identity governance and security tools with a single, continuously updated control plane that governs every identity across an organization, whether human, machine, or AI agent. The round was co-led by Accel, Greylock Partners, and CRV, with participation from Hetz Ventures, AlphaDrive Ventures, and strategic angel investors. Oak’s solution is already generally available and deployed across enterprise customers.
Identity is the gateway to the modern enterprise, determining who is let in and who is kept out, which makes it the primary attack vector in security, yet most companies still cannot say who has access to their systems at any given moment. According to Gartner, by 2028, 70% of CISOs will adopt identity visibility and intelligence capabilities to shrink the sprawling identity attack surface. AI-native from its foundation, Oak connects to any system and builds new connectors in hours rather than the months legacy systems require, building its understanding of every identity from raw evidence instead of the static records traditional tools depend on.
Oak was founded by CEO Shai Morag, a serial cybersecurity entrepreneur with more than two decades in the field who previously founded and sold three companies, including Integrity-Project, acquired by NVIDIA’s Mellanox in 2014; Secdo, acquired by Palo Alto Networks in 2018; and Ermetic, acquired by Tenable in 2023, where he then served as CPO. He is joined by co-founder and CPO Tal Marom, who led product teams at Tenable and Salesforce. Oak is using part of the funding to expand its team of security and AI experts and will showcase its technology at Black Hat USA in August 2026.
KEY QUOTES:
“The market has reached a breaking point, and I had the chance to bring together the people who understand identity, security, and AI best.”
“I’ve built several companies in this space, so I understand why identity has stayed broken for so long. The tools were never built to work as one, and adding more of them was never going to fix it. Oak is the platform the industry has needed for twenty years, and could never build until now.”
Shai Morag, CEO and Co-Founder, Oak
“We spent months speaking with more than 100 CISOs and IAM leaders, and they all share the same problems of running too many disconnected tools, being unable to see how access is used, and no way to govern AI agents.”
“Just as CNAPP consolidated the fragmented cloud security stack, identity is now at that same inflection point, and Oak is designed to be the platform that brings it all together and turbocharges the security teams defending the enterprise.”
Tal Marom, CPO and Co-Founder, Oak
“Backing Shai a second time was one of the easiest decisions we’ve ever made.”
“He and his team have spent their careers solving the hardest problems in enterprise security, and identity is the biggest one left standing. Oak has the team, the timing, and the technology to take on the whole category, and we’ve committed at inception to help them do it.”
Andrei Brasoveanu, Partner, Accel
