Neo

Neo Security is an Israeli-US cybersecurity company that provides a real-time control layer to manage and secure the deployment of AI agents within enterprise environments. The firm emerged from stealth in July 2026 with $100 million in capital, which consisted of a $25 million seed round in 2025 and a $75 million Series A round. The funding was co-led by Andreessen Horowitz and Bessemer Venture Partners, with additional participation from Craft Ventures and Merlin Ventures. The company was founded by veterans from prominent cybersecurity firms. The leadership team includes CEO Nicholas Warner, the former COO of SentinelOne; CPO Shlomi Salem; and CTO Eran Shirazi. The founders' collective experience at companies like SentinelOne, Wiz, and Palo Alto Networks informs Neo's approach to a new set of security challenges. Warner was instrumental in building SentinelOne’s go-to-market strategy through its IPO, while Shirazi previously co-founded EasySend and served in the Israeli Defense Forces' Unit 8200. Neo's platform is designed to address the risks associated with agentic software, where AI capabilities are integrated into tools like browsers, SaaS platforms, and developer applications, allowing them to act autonomously with valid user permissions. The company's solution provides security operations (SecOps) teams with tools for inventory, intelligence, attribution, and policy enforcement. The platform automatically maps all AI agents and AI-enabled applications, maintains a knowledge base of their capabilities and risks, records a detailed audit trail of all actions, and enforces policies to block potentially risky activity before it happens. This enables organizations to govern how AI behaves and secure its adoption without hindering business operations. Headquartered in Boston and maintaining a development center in Tel Aviv, Neo targets the enterprise AI security market, positioning itself to create a new software category focused on the governance of autonomous systems.
