A cybersecurity startup just stepped out of stealth mode with $66 million to solve a problem most companies haven't faced yet: how to give AI agents their own digital identities and control what they do.

NewCore announced the funding on Monday, saying companies will soon need to authenticate, govern, and monitor AI agents the same way they manage human employees. The round was led by Cyberstarts, a venture firm that focuses on cybersecurity, with Index Ventures and Evolution Equity Partners also chipping in. The investment values NewCore at $300 million after the money came in.

The big idea here is that AI agents — software that can act autonomously, like booking meetings or processing transactions — are starting to act like employees. They need credentials, permissions, and oversight. But right now, most companies have no system to tell a legitimate AI agent from a malicious one. NewCore wants to be the identity provider for those agents.

Think of it like this: when a human starts a job, they get a badge, a laptop, and access to specific systems.

The $66 million seed round is unusually large — most seed rounds are in the single-digit millions. But the problem NewCore is tackling is new, and investors are betting it'll become essential as more companies deploy AI agents. Cyberstarts has a track record of backing early-stage cybersecurity firms that later become major players.

NewCore hasn't revealed many details about its product yet, but the company says it'll focus on three things: issuing and managing digital identities for AI agents, setting rules for what each agent can and can't do, and logging every action an agent takes so companies can audit them later.

The timing makes sense. Major tech companies like Microsoft and Salesforce have been rolling out AI agents that can work alongside humans. But security experts have warned that these agents introduce new risks — they can be hijacked, tricked into leaking data, or used to launch attacks inside a network. NewCore's approach is to give each agent a verifiable identity that can be revoked if something goes wrong.

For now, NewCore is still building its product and hiring. The company plans to use the funding to grow its engineering team and start pilot programs with early customers. It hasn't said when the product will be generally available.

This is one of those stories where the money is big because the problem is new. If AI agents really do become as common as smartphones in the workplace, every company will need a way to manage them. NewCore is betting it can be the one they call.
