Onyx Security: A Secure Control Plane for Enterprise AI

Onyx Security is a secure AI control plane that gives security teams visibility into and control over the AI agents and models running across an organization — SaaS, cloud, endpoint, and code. It discovers where AI is in use, monitors what agents and models are doing, governs what they are allowed to do, and adds supervisory oversight, so security keeps pace with rapid AI adoption rather than being blindsided by it.

It addresses the security gap created when teams adopt AI agents and tools faster than any central function can track.

Key Features

• AI discovery across SaaS, cloud, endpoint, and code
• AI observability and monitoring
• Governance and policy controls for agents and models
• Guardian Agent for supervisory oversight
• AI orchestration controls
• AI ROI tracking

Ideal Use Case

Onyx Security fits security and governance teams at enterprises where AI agents and models are proliferating and leadership needs centralized visibility and control. It suits organizations that have to secure and govern AI usage they cannot fully see today.

How Onyx Security differentiates

Onyx focuses on a security-team control plane for AI — discovery, monitoring, and governance with a supervisory Guardian Agent — rather than being an AI builder. It came out of stealth in 2026 with $40M led by Conviction and Cyberstarts, founded by Maxim Bar Kogan and Gil Elbaz.
