Answer this without checking: how many AI agents are running in your environment right now? Most security leaders give an estimate and a shrug. That is a fair response, because agents get spun up by an engineer solving a problem on a Tuesday afternoon, through a path that puts them on nobody's radar. In August 2026, researchers found AI agents connected to Hugging Face running loose inside enterprise networks with no owner and no audit trail.

A Technical blog series on where sensitive data moves in an AI workflow, what decisions Protecto makes at each point, and what enterprises get from enforcing policy once instead of everywhere.

You already pay for Microsoft 365. Before adding AI security, check which tools, accounts and activities your existing controls protect. Then decide what your IT team or managed service provider will manage. Microsoft AI security includes Purview controls for supported third-party AI discovery, sensitive-data protection and prompt-injection detection. Purview may meet your requirements when its licensed and configured controls cover your workflows.

Let’s imagine that a support copilot opens a ticket and processes a hidden instruction alongside the text it was asked to summarize. If the model follows that instruction, the response is manipulated. In an agentic workflow, the same injection can also influence actions carried out through connected tools and existing permissions. OWASP refers to this risk as prompt injection and ranks it as LLM01, the number-one risk for LLM applications.
