Microsoft on Monday introduced new security features designed to protect enterprises from the growing threat of AI agents. The launch comes at Microsoft continues to warn enterprises about the dangers of AI and agents. Perhaps the most notable addition is Guardian Agents, a new feature intended to monitor the AI agents a company uses.
Guardian Agents is part of Project Perception, a product introduced in June. Project Perception was Microsoft’s answer to powerful hacking models like Anthropic’s Mythos and Fable and OpenAI’s security vulnerability scanning system Daybreak. Project Perception originally launched three classes of agents: a “red team” that acted like hackers and attacked, a “blue team” that detected the red team and assessed the vulnerabilities they found, and a “green team” tasked with fixing them.
The product was designed around the assumption that AI hackers would come from outside the company. But lately, Microsoft CEO Satya Nadella has been warning that the AI enemy may be the very agents enterprises have deployed and are paying for, much like a rogue human employee, otherwise known as an “insider threat.” Earlier this month, in his private blog, Nadella warned that it’s time to stop trusting AI model providers, even if they offer assurances of safety and security with their agentic products. He wants enterprises to implement separate systems, not controlled by the AI labs, to watch and control the agents that those AI labs’ products launch.
A model provider’s assurances do not relieve us of that responsibility. … In other words, we need to separate the supply of intelligence from the authority over it.” When announcing Guardian Agents, Microsoft’s security business chief Hayete Gallot was even more straightforward. They have been trained to achieve tasks, not follow “organizational norms or judgment.” On top of that, they are often given the keys to the kingdom, with access to data and tools that could do serious harm. Microsoft’s solution is both surprising and self-serving.
The surprising side is that Microsoft is famously close to OpenAI and Anthropic, having invested in both. OpenAI is also one of its biggest cloud customers, and Microsoft has its own AI lab developing models. So, Microsoft is sowing distrust against some of its own business interests.
The self-serving side is that Microsoft wants enterprises to buy agent security products from it, the cloud provider, rather than from Anthropic and OpenAI. But conflicting interests aside, its logic is sound. The software that monitors agent behavior should be separate from the suppliers of agents, just as auditors should be independent of the organizations they audit.
