## Our take

What our shortlists say about the one we picked.

### [WitnessAI Platform](https://cybersectools.com/tools/witness-ai-product)

Best for: Network-level AI visibility with no endpoint clients

It belongs here because it sees AI use from the network, which means no endpoint clients or browser extensions to roll out. It fits mid-sized and large companies that want staff-use controls and agent governance in one place. Its listed integrations are few, so ask how it connects to your identity, logging and network setup before you commit.
