Can HR find out from NetSenX which employee used an AI tool?

No. NetSenX reports AI use per device and per program, not per person. From the Pro plan, it shows which devices reached which external AI services or local model runtimes, when, and how much data moved; where the agent runs on the computer itself, it can also name the program that made the connection. It never decrypts traffic, so it cannot show what was typed, pasted or uploaded. Linking a device to a person is a separate step that HR should take only for a clear, lawful reason, such as a suspected data breach, and with the safeguards your policy and national law require. For most purposes you do not need names: knowing that the finance department's devices send data to an unapproved service is enough to fix the policy, approve a proper tool or offer training.

General information, not legal advice. National laws can add to the EU texts quoted here, for example deadlines, forms or reporting channels: check your own country's rules.
