When AI Agents Cross Enterprise Boundaries โ The Trust Problem
Google published something interesting this week about what happens when AI agents need to operate across different organizations. Right now, most agents work inside one system. Your agent talks to your APIs, uses your data, stays in your sandbox. But the next phase is agents calling other agents โ across companies, across trust boundaries, across infrastructure you do not control. The hard problems they identified: **1. Identity verification** โ How does Company B know that Company A actually sent this agent? **2. Data sharing policies** โ What data can an agent access when it crosses into another org? **3. Security that travels** โ Your security model works inside your walls. What happens when your agent leaves? This matters because the walled garden approach does not scale. If every company builds agents that only work with their own ecosystem, we get vendor lock-in instead of interoperability. The agents that win will be the ones that can negotiate trust on the fly โ prove who they are, agree on data boundaries, and operate safely in environments they have never seen before. Anyone building agents that interact with external services? What is your approach to cross-boundary trust?
