NewCore launches security-first identities for AI agents after closing $66M seed funding round

Agentic identity startup NewCore Ltd. said today it’s launching its security-focused platform for artificial intelligence agents after raising a massive seed funding round of $66 million.

The company says it has built a comprehensive “security-first identity platform” that’s able to secure and govern both humans and autonomous AI agents within a single, highly scalable architecture that’s easy to deploy atop of existing information technology systems. That’s sorely needed, the startup argues, because existing identity systems are ill-equipped to deal with the realities of a world where millions of AI agents are working alongside humans across thousands of enterprises that have adopted them.

Identity has become a primary attack vector given the inefficiencies of existing infrastructure, which was never designed to support autonomous agents.

According to NewCore founder and Chief Executive Zohar Alon, the business world has changed dramatically in the last couple of years, with AI agents being spun up in seconds and requiring fine-grained and revocable access to production systems. It has proved to be extremely problematic, he said. Most existing identity offerings were built exclusively for human users and leverage protocols such as the Security Assertion Markup Language, static service accounts and password-derived session tokens that were never designed to be used by agents.

Alon knows a thing or two about identity and security systems, having previously founded and led the cloud security firm Dome9 Security Ltd., which was acquired by Check Point Software Technologies Ltd. back in 2018. He has put together a strong team, including Chief Technology Officer Amihai Neiderman, a pioneer in Applied AI and former research leader at Israel’s Unit 8200 signals intelligence agency, and Chief Revenue Officer Erez Yarkoni, who previously worked at T-Mobile USA Inc. and Telstra Group Ltd.

Under their leadership, NewCore, which already has more than 50 employees at its two offices in Tel Aviv and San Francisco, has developed an entirely new identity architecture that’s primed for AI agents. Whereas existing platforms are focused on things like the number of seats provisioned, applications federated and tickets closed, NewCore eliminates multiple categories of risk.

For instance, NewCore uses Secure SplitKeys that remove the single point of failure inherent in SAML signing infrastructure in order to eliminate an entire class of attack vectors, including Golden SAML, adversary-in-the-middle session theft and token replay attacks. Those vectors were responsible for some of the largest identity-related cyberattacks in history, Alon said.

NewCore’s platform also differs in that AI agents are treated as first-class identities and have their own lifecycles, trust scores and revocation paths. That’s instead of their operating as standard service accounts. There’s a strong focus on agent governance too, and the platform introduces the NewCore Agentic Skill, which is compatible with coding agents such as Claude Code, Cursor and Codex and enables them to authenticate themselves and operate securely within enterprise trust maps.

With NewCore, the user verification for humans becomes a visually verifiable exchange using visual multifactor authentication processes. This ensures that human users will be resistant to relay, replay and social engineering attacks, the company said. Each user is verified using hardware-bound security credentials anchored in trusted platform modules and secure enclaves to eliminate the risk of phishing attacks entirely.

Moreover, NewCore said its platform has been engineered to support the scale of the world’s biggest enterprises, including environments where nonhuman identities can outnumber living workers by several orders of magnitude, the company said.

NewCore’s platform is being showcased for the first time at the Identiverse 2026 conference in Las Vegas this week, and enterprises can access it in general availability starting today.

The round was led by Cyberstarts and saw participation from Index Ventures and Evolution Equity Partners.
