Governance

Microsoft Open Trust Stack AI agent governance is Microsoft’s 2026 pattern for making agents testable, enforceable, and observable. The practical model is simple: use ASSERT before release, ACS during runtime, and OpenInference traces across both so engineering, security, and SRE teams can inspect the same evidence. What does Microsoft mean by the Open Trust Stack? Microsoft Open Trust Stack AI agent governance is a production governance approach announced at Build 2026 that combines two open-source projects, ASSERT and Agent Control Specification, with OpenInference telemetry. ASSERT means Adaptive Spec-driven Scoring for Evaluation and Regression Testing, while ACS defines portable runtime controls for agent behavior. Microsoft frames the audience as the 6 to 13 million generative AI developers building agents across frameworks such as LangChain, CrewAI, LiteLLM, and OpenAI. The stack is not a single hosted product or a replacement for secure application design. It is a lifecycle: evaluate agent behavior before release, enforce policies while the agent acts, and preserve trace evidence for debugging, audits, and regression analysis. The important takeaway is that governance becomes an engineering system, not a policy document. ...

Use this checklist to evaluate AI coding tools before your next procurement decision. The short answer: screen for security compliance first, then score governance controls, then run a context-depth pilot — in that order. Any tool that fails the security gate gets dropped before you spend time benchmarking features. Why Engineering Leaders Need a Formal AI Coding Tool Evaluation in 2026 AI coding tools have crossed the critical adoption threshold in 2026, yet most engineering organizations are running without adequate governance. 84% of developers now use or plan to use AI coding tools — up from 76% the previous year — but only 32–45% of engineering leaders have formal governance policies in place. The consequences are already visible in the data: incidents per pull request increased 23.5% and change failure rates are up roughly 30%, even as PR velocity climbed 20% year-over-year. This is the velocity-quality paradox. AI tools make teams faster at shipping code, but without formal evaluation and governance, they also accelerate the rate at which problematic code reaches production. The AI coding tools market reached $12.8 billion in 2026 (up from $5.1 billion in 2024), which means vendor marketing has far outpaced organizations’ ability to evaluate tools rigorously. Engineering leaders who rely on developer preference surveys or feature comparison sheets instead of a structured evaluation framework are systematically making procurement decisions without visibility into what matters most at team scale. ...

Ninety-two percent of Fortune 500 companies have deployed at least one AI coding assistant — yet 78% of enterprises simultaneously report employees using unauthorized AI tools for coding tasks (Gartner, 2025). That gap between sanctioned deployment and actual developer behavior is the governance problem of 2026. Engineers who can’t get fast approval for the AI tool they want will use their personal Claude.ai account, their individual Cursor subscription, or a free Copilot tier on a laptop that has never seen your DLP policy. The code they paste in takes your intellectual property, your customer data, and your regulatory posture out of scope — silently, without a ticket, without a log entry. This guide provides the framework, the policy language, and the 90-day roadmap to close that gap. ...
