The governance infrastructure for autonomous AI agents.
They initiate payments, access data, communicate with counterparties, and execute code — with increasing autonomy. They are not software to be secured. They require governance infrastructure.
Agent Shield was built on this thesis. The platform provides constitutional governance for AI agents: structural containment that ensures every autonomous action operates within defined boundaries, with full audit trails, real-time detection, and regulatory compliance.
This is not monitoring. It is not security tooling adapted for agents. It is purpose-built governance infrastructure. Agent Shield is the reference implementation of the AGS v2.1 standard, published by AgentGoverning.
Agent Shield was founded by Andrew Hoyle, a qualified accountant and software engineer based in the United Kingdom. The combination of financial services expertise and deep technical capability shaped the platform's approach: treating AI agent governance as a structural governance problem, not a cybersecurity problem.
This perspective — that agents require the same governance rigour as human actors operating within authority limits — is what distinguishes Agent Shield from every other approach in the market.
We did not just publish a standard. We built the working system, and it is being rolled out across multiple products.
