Galileo released Agent Control on March 11, 2026 — an open-source governance layer (Apache 2.0) that lets enterprises write policies once and deploy across all agents with five decision outcomes: deny, steer, warn, log, or allow. Initial integrations include Strands Agents, CrewAI, Glean, and Cisco AI Defense, addressing the absence of a vendor-neutral runtime governance standard. The release frames agent runtime governance as infrastructure rather than a product, directly challenging proprietary guardrail vendors.
