Boston-based Neo Security emerged from stealth on July 20, 2026 with $100 million in combined seed and Series A funding to build what it calls the "Agentic Software Control" layer for enterprise IT — a real-time control plane for AI agents, agentic browsers and traditional applications acquiring autonomous capabilities. The round was led by Andreessen Horowitz and Bessemer Venture Partners, with participation from Craft Ventures and Merlin Ventures.
The Team And Its Pedigree
Neo's founding trio — CEO Nick Warner, CTO Shlomi Salem and product lead Eran Shirazi — are veterans of SentinelOne, Wiz and Palo Alto Networks. Warner built SentinelOne's go-to-market organization and took the company public as COO in 2021; Salem spent more than a decade running detection engineering there; Shirazi previously ran a vulnerability research group in the Israeli Defense Forces' Unit 8200.
The Product Wedge
Neo cites Gartner data showing that just 5% of enterprise applications embedded agentic capabilities in 2025 — but 40% will by the end of 2026. Its platform delivers five capabilities: a "Neoverse" software inventory of AI agents, MCP servers and plugins; capability-and-risk intelligence; real-time attribution mapping actions back to the responsible human, identity or agent; group- and identity-specific policy control over tool calls, API access and data movement; and native enforcement that blocks risky prompts and models without handing off to another tool.
Why Investors Are Buying
"Agentic AI is creating a new security category as enterprise environments transform," said Bessemer partner Elliott Robinson. Andreessen Horowitz general partner Zane Lackey added that "employees are rapidly adopting AI agents and software vendors are embedding agentic capabilities into products enterprises already use." The Neo bet extends a broader financing wave into agentic security, following Beacon Security's $13M seed and companies like Wiz and Palo Alto Networks racing to expand AI-security offerings.
