A security checkpoint that sits between AI agents and the tools they're allowed to use, blocking dangerous actions before they run.
Best alternatives to Onyx Security in 2026
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.
