About
Onyx Security is an Israeli AI agent security startup founded in 2024 to address the emerging attack surface created by enterprise AI agent deployments. As organizations deploy autonomous AI agents that can take actions, access data, and interact with external services, Onyx identified a critical security gap: existing enterprise security tools were built for human users and traditional software, not for AI agents that operate autonomously and can be manipulated through prompt injection, model compromise, or tool misuse. Onyx was founded to build the security infrastructure layer that makes enterprise AI agents safe to deploy at scale.\n\nOnyx's platform monitors, governs, and protects enterprise AI agent deployments in real time — detecting anomalous agent behavior, enforcing least-privilege access policies, preventing prompt injection attacks, and providing audit trails for agent actions. The product is designed for Fortune 500 enterprises deploying AI agents in business-critical workflows where a compromised or misbehaving agent could exfiltrate data, take unauthorized actions, or cause operational harm. Onyx integrates with leading agentic AI platforms and enterprise security infrastructure without requiring architectural changes to existing agent deployments.\n\nOnyx Security raised $40 million in March 2026 and counts Fortune 500 companies among its early customers — a remarkable milestone for a company less than two years old. The funding and customer traction validate both the urgency of the AI agent security problem and Onyx's technical approach. The company is positioned to lead the AI agent security category as enterprise agentic deployments accelerate globally and CISOs begin to demand purpose-built security controls for AI systems operating in production environments.
