Neo Security bags $100M to build the secure control layer for enterprise AI agents

What happened

Neo Security Inc., a startup focused on agentic software control, announced it has raised $100 million in a funding round led by Andreessen Horowitz and Bessemer Venture Partners, with additional backing from Craft Ventures and Merlin Ventures. After years operating in stealth mode, Neo Security is now stepping into the spotlight to build a secure control layer for enterprise AI agents.

Why it matters

As enterprises increasingly deploy AI agents to automate complex tasks, controlling and securing these agents becomes a major challenge. Neo Security’s technology aims to create a security framework that tightly manages how AI agents operate, interact, and access sensitive data and systems. This addresses the growing risk AI agents pose when left unchecked, such as unauthorized actions, data leaks, or compliance failures. For enterprise IT and security teams, this kind of control layer pressures existing cloud and software providers to improve safeguards or risk being bypassed by more autonomous AI agents.

What to watch next

How effectively Neo Security can integrate with enterprise environments and operate at scale will determine its impact. Investors will watch whether it can translate its funding into products that reduce AI agent risk enough to drive broad adoption. Also critical will be observing how AI platform providers respond to this new layer of security and control—whether they build similar solutions internally or partner with startups like Neo Security. The pace of AI agent adoption in regulated and security-sensitive industries will shape demand for these controls.
