Cybersecurity startup NewCore emerged from stealth with $66 million in funding on Monday, aiming to solve a challenge it believes many companies will soon face as they deploy AI agents: how to authenticate, govern, and control them at scale.

The seed round was led by cybersecurity-focused venture firm Cyberstarts, with participation from Index Ventures and Evolution Equity Partners, valuing NewCore at $300 million after investment.

Companies are increasingly treating AI agents as workplace participants rather than software tools. Goldman Sachs last year tested AI coding agent Devin as a new employee, while McKinsey said earlier this year that 25,000 AI agents already work alongside its 60,000 employees. NewCore is betting companies will eventually need to manage those digital workers much like human employees.

For co-founder and chief executive Zohar Alon (pictured above, center), the opportunity stems from a belief that identity systems have become one of the weakest links in enterprise security. Alon, who previously founded cloud-security startup Dome9 before its acquisition by Check Point, said the rise of AI agents convinced him and his co-founders that existing identity platforms were ill-suited for a future in which software workers operate alongside human employees.
