Exabeam launches Praxen, an open-source tool to verify AI agent behavior

Security intelligence and management solutions company Exabeam Inc. today introduced Agent Behavior Verification, a pre-deployment security discipline for artificial intelligence agents, and released Praxen, an open-source tool that tests an agent against the job it was hired to do before it ever goes live.

Praxen puts the idea into practice. The company pitches ABV as a pre-deployment check, one that runs before the runtime monitoring its Agent Behavior Analytics product already provides kicks in. Vulnerability scanning and red teaming probe an agent once it is running. ABV looks at the whole agent first and asks a blunter question: Does what it can actually do line up with the role it was given?

That question extends a push Exabeam has made through 2026. The company expanded its Agent Behavior Analytics product to cover agents across ChatGPT, Microsoft Corp.’s Copilot and Google LLC’s Gemini in April, then stretched it across Google Cloud’s agent ecosystem weeks later. ABA watches agents in production. ABV is the front end of the same strategy, applied before an agent is switched on.

Released under the Apache 2.0 license, Praxen is a reference build of the discipline. It starts from an ABV remit, which is Exabeam’s term for a policy contract setting out what an agent may do, what it may touch and where it has to stop. Praxen measures that remit against the agent’s real tools, configurations, memory, integrations and operating environment, then reports where the two diverge. Each report lists specific findings, recommends fixes and assigns a maturity score for the agent’s security posture.
