The moment organizations started deploying AI agents at scale, they created a security problem nobody had fully solved: these agents need identities, permissions, and access — and the existing infrastructure wasn’t built for them. Oak, a cybersecurity startup, just raised $60 million and stepped out of stealth to fix exactly that, according to a Globes report on the funding round.
The raise, led by Index Ventures and Cyberstarts, positions Oak squarely at one of the fastest-growing fault lines in enterprise security. AI agents don’t just query data passively — they act, make decisions, and chain together with other systems. That autonomy creates a sprawling identity surface that traditional identity and access management tools were never designed to handle.
The Problem Oak Is Built to Solve
As TechCrunch detailed, Oak’s platform targets the compounding identity mess that AI agents are actively making worse. When a single AI agent can spin up sub-agents, call APIs, and inherit permissions across cloud environments, even one misconfigured identity becomes a potential blast radius for a serious breach. Oak’s approach centers on giving security teams visibility and control over non-human identities — the machine accounts, service tokens, and agent credentials that now outnumber human users in many enterprise environments.
This isn’t a niche concern. Non-human identities have quietly become one of the most exploited vectors in modern attacks. Threat actors increasingly target service accounts and API keys precisely because they tend to be over-privileged and under-monitored. Oak’s pitch is that as AI agent deployment accelerates, this problem scales exponentially — and that legacy IAM vendors aren’t moving fast enough to keep up.
A Crowded Market, But a Defined Lane
The identity security space is getting competitive fast. Consolidation is already underway — Future Wire recently covered how a $1 billion deal looked set to merge two data security players into a combined identity platform. Oak is carving out a more specific lane: not just identity in the broad sense, but identity as it applies to the agentic AI layer that enterprises are now building on top of their cloud infrastructure.
The $60 million raise gives Oak the runway to build out its platform and go-to-market motion before larger incumbents — CrowdStrike, Palo Alto Networks, Microsoft — fully commit resources to the same problem. Index Ventures and Cyberstarts have both backed security winners before, and the co-lead structure suggests strong conviction from both sides of the Atlantic. Oak has not yet disclosed specific customer counts or revenue metrics, but the size of the round at the seed-to-Series A boundary signals investors are betting on the urgency of the category, not just the company’s early traction.
The broader context matters here: enterprise AI adoption is accelerating faster than security tooling can adapt. Every new agentic workflow an organization deploys is another set of non-human identities that need to be provisioned, monitored, and eventually deprovisioned. Oak’s window to define this category is real — and with $60 million in the bank and stealth behind it, the clock is now running.
