Verified Digital Agents (VDA)

getvda.ai · Verified Digital Agents

Governance for AI agents that you can prove — a composable suite. Witness seals and anchors decisions; C2MD turns compliance standards into governance agents can follow; ACP holds governance in git and reviews, tests and signs changes; Onboarding admits agents and issues verifiable credentials; human-in-the-loop surfaces what exceeds an agent's limits. Git holds the rules, Witness holds the events. Governance lives in plain Markdown, so VDA governs best-of-breed agents from any provider or framework.
