MicrosoftExcellent and timely piece, particularly the Marketplace publisher section. As an ISV publishing AI agent solutions on
Azure Marketplace right now, the point about making security a go-to-market narrative rather than a compliance checkbox is exactly right.
We built our platform on Azure AI Foundry with a 12-step analysis pipeline where 50+ specialist AI agents process sensitive business documentation. The architectural decisions you describe here - least privilege at every tool boundary, treating every data source as untrusted by default, constraining agent scope to specific governance disciplines, are ones we made early precisely because the blast radius of a compromised agent handling board-level intelligence is not theoretical.
One angle I'd add for Marketplace publishers specifically: the trust signal gap. Enterprise buyers evaluating AI-powered SaaS on Marketplace are increasingly asking about adversarial testing, but there's no standardised way to surface that evidence in the listing itself. ASR metrics in security documentation is a strong recommendation, I'd love to see Marketplace certification evolve to include behavioural security evidence alongside the infrastructure-level requirements you mention. The shift from "secure the perimeter" to "secure the reasoning" is the paradigm change that most organisations haven't internalised yet. This post should be required reading for anyone shipping agents into production.
