Oak Raises $60 Million to Replace Fragmented Identity Security Tools With a Single Platform

Key points

• Oak, a cybersecurity startup founded in late 2025, raised $60 million in seed funding led by Accel, Greylock Partners, and CRV.
• The company is already selling its product, an Identity Operating System that tracks every human, AI agent, and automated account inside an organisation.
• Co-founder Shai Morag previously built and sold three security companies, including Secdo to Palo Alto Networks and Ermetic to Tenable.
• Oak says it interviewed more than 100 chief information security officers before building the platform.
• The company operates from Tel Aviv and San Francisco.

A startup called Oak came out of hiding this week, announcing $60 million in seed funding, meaning the very first institutional money a young company raises, to build what it calls an Identity Operating System.

The idea sounds abstract. The problem it solves is not.

Every organisation runs on accounts: employee logins, software bots, cloud service accounts, and increasingly AI agents, meaning automated software programs that take actions on a company's behalf. Right now most companies manage these across a patchwork of separate tools that rarely talk to each other. A new employee joins, gets access to twelve systems, and when they leave, some of those access rights quietly stay open. Nobody notices. That gap is how many data breaches start.

Oak's platform connects to every application a company uses, whether stored in the cloud, on the company's own servers, or bought as a subscription service, and builds a live map of who can access what and whether they actually use it. The platform then flags rights that look too broad or too risky.

Why does this matter to ordinary employees?

It matters because unused or forgotten account permissions are one of the most common ways criminals move through a company's systems after an initial break-in. If a single compromised password gives an attacker access to everything instead of one small corner, the damage grows fast. Tools like Oak's are designed to shrink that exposure automatically.

Co-founder Tal Marom said the team spoke with more than 100 chief information security officers before writing a line of code. Their consistent complaint: too many disconnected tools, no clear picture of how access is actually used, and no way to govern the new wave of AI agents that now act inside company systems alongside human staff.

Co-founder and CEO Shai Morag has built and sold security companies before, including Ermetic, an identity security firm acquired by Tenable in 2023, and Secdo, acquired by Palo Alto Networks in 2018. That track record likely helped Oak attract investors including Accel, Greylock Partners, CRV, Hetz Ventures, and AlphaDrive Ventures.

The product is already generally available, SecurityWeek reported, which is notable at seed stage. Most startups raise this kind of money before they have a finished product.

For employees at companies that adopt Oak, the practical effect should be invisible: tighter permissions in the background, fewer dormant accounts sitting around as open doors. For security teams, it means one dashboard instead of many.

Ordinary staff do not need to act on this news. But if your employer asks you to re-verify your access rights to certain systems in the coming months, this is the kind of platform behind that request.
