## Our take

What our shortlists say about the one we picked.

### [Cyera Agent Guardian](https://cybersectools.com/tools/cyera-ai-guardian)

Best for: Data security teams worried about AI data exposure

It is here for the data side of AI posture, which matters if your biggest fear is sensitive records ending up in a model or a prompt. It suits data security teams that already classify data and want that view stretched to AI, at any size from SMB to enterprise. The trade-off is depth on the AI stack itself, so ask how far it goes on model and agent settings, not only on data.
