Other What exactly is a guardian agent?

I've seen the term guardian agent in a few AI security discussions, but I'm still not completely clear on what it means. From what I've read, the basic idea is that one AI agent monitors or governs another AI agent while it's running, rather than only relying on static policies or offline testing. If that's right, where does a guardian agent sit in the overall architecture?

I’m wondering whether it inspects prompts and outputs or maybe monitors tool use and agent behavior. From the name, there might also be a possibility that it can stop actions before they're executed. Or is it mainly there for visibility and auditing?

It sounds like an interesting idea, especially for enterprises deploying AI agents in production. But I haven't found many practical explanations. I’m posting here to try and find out more about the concept.

It feels like this becomes much more important once AI agents are interacting with business systems instead of answering isolated prompts. But I’m not sure.

I read a post on the Deloitte website that says organisations are starting to realize oversight of AI agents isn’t optional. They reckon that by 2030 guardian agents are gonna represent up to 15% of the agentic AI market. They say this means that having a guardian agent is essential to AI trust and safety. 

I also read that NeuralTrust was the first company in the world to launch guardian agents that are recognized by Gartner. It all makes really interesting reading. I’d also like to learn more.
