Onyx Security
A control panel that finds every AI agent running across your company's SaaS apps, cloud, developer laptops, and code repos, maps what each one can access, and steps in when something looks off.

Description
AI agents don't just live in one place anymore — they show up inside SaaS tools, cloud infrastructure, developer laptops, and code repositories, often installed by different teams who never talk to each other. Onyx Security is built to be the one place that sees all of them at once: it finds every agent, figures out what permissions and data each one can touch, and has a "Guardian Agent" that watches continuously and steps in if something behaves like it shouldn't — excessive permissions, data exposure, unauthorized actions.
Onyx Security is a control plane for securing AI agents and models across the enterprise, discovering agents across SaaS, cloud, developer workstations, and code repositories, then mapping their permissions and behavior. Its Guardian Agent provides continuous monitoring and intervenes on anomalies like excessive permissions, data exposure, or unauthorized actions. Pricing isn't public — enterprise sales only. It targets security, governance, and AI teams, plus CISOs, trying to enable AI adoption without losing compliance control.
💬 Our review
The short version: if AI agents at your company are scattered across SaaS tools, cloud, and dev laptops with nobody having a full picture, Onyx's pitch is being the single control plane that sees and governs all of it at once.
Onyx's breadth of discovery surface — SaaS plus cloud plus developer workstations plus code repos — is wider than more narrowly scoped competitors like SolonGate (MCP proxy only) or a16y.ai (endpoint-focused), making it a stronger fit for a company that doesn't know where its "shadow AI" problem even lives yet. The Guardian Agent's continuous intervention model is similar in spirit to a16y.ai's Runtime Enforcement, so the practical choice between them often comes down to which surface each vendor covers best in your specific environment — worth testing both in a POC rather than picking on marketing copy alone, since none of them publish independent benchmarks.
