Oak, an AI-native security company building what it calls an Identity Operating System, has come out of stealth with $60m in seed funding to tackle one of the most persistent gaps in enterprise security.
The round was co-led by Accel, Greylock Partners and CRV, with Hetz Ventures, AlphaDrive Ventures and a group of strategic angel investors also taking part. Rather than remaining in development, Oak’s platform is already generally available and running in production across enterprise customers.
The company argues that identity has become the front door of the modern enterprise and, consequently, the leading route for attackers. Despite this, many organisations remain unable to state with confidence who can access their systems at any moment.
Legacy governance tools were designed for an era of human users and stable infrastructure, and the rapid multiplication of human, machine and AI-agent identities has left them behind.
Gartner projects that 70% of CISOs will take up identity visibility and intelligence capabilities by 2028 as they look to contain a widening identity attack surface. While established vendors have attempted to retrofit AI onto ageing platforms, Oak claims a different starting point, with an architecture designed around AI from day one.
Oak’s technology plugs into any system and can spin up new connectors within hours, a process the company says takes legacy providers months. Instead of relying on the static records used by traditional tools, the platform derives its picture of each identity from raw evidence. On this foundation, Oak is constructing a single operating system to oversee every identity, human, machine or AI agent, across its full lifecycle.
The business is led by CEO and co-founder Shai Morag, a serial cybersecurity entrepreneur with over two decades of experience who previously founded and sold three companies: Integrity-Project, bought by NVIDIA’s Mellanox in 2014; Secdo, purchased by Palo Alto Networks in 2018; and cloud identity firm Ermetic, acquired by Tenable in 2023, where he went on to serve as CPO.
He is joined by co-founder and CPO Tal Marom, formerly a product leader at Tenable and Salesforce. Part of the new capital will go towards recruiting further security and AI specialists as the full platform is built out.
Oak CEO and co-founder Shai Morag said, “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.”
Oak CPO and co-founder Tal Marom said, “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.”
