Trail is a modular AI governance and GRC platform spanning two tracks: AI Governance for enterprises scaling AI, and GRC Agents for compliance teams automating common tasks. Trail maintains a centralized registry of AI systems, models, agents, and vendors with automated EU AI Act risk classification, and operationalizes compliance through curated frameworks, automated control mapping and evidence tracking, audit mode, and a library of 170+ curated AI risks and controls. Trail also provides safety mechanisms for using AI agents - such as the copy-on-write (COW) mechanism, evaluations, and scoring, to ensure human review in automated workflows.
