Built in Alicante for the EU mid-market.

NetSenX was started by a practitioner who spent a decade in EU mid-market security teams watching the same pattern repeat. The detection stack gets louder every quarter, the budget gets tighter every fiscal year, and the alert backlog grows on a schedule no human SOC can sustain. Vendors call this “coverage.” The teams living with it call it an alert factory.

NetSenX exists because more alerts do not buy more security. The mathematical work behind our proprietary LGGT+ engine — published as arXiv:2603.28558v1 — gives us an upper bound on false positives that is derived, not tuned. That bound is not a marketing claim. It is an inequality, and anyone with a copy of the paper can check the derivation. How tight it binds on your network depends on how much labelled benign traffic has been calibrated — which is why the product tells you the bound your own data supports, and tells you plainly when it does not yet support one.

The rest of NetSenX exists to make that guarantee operational: an AI Analyst Core that writes the analyst notes, an audit log that survives the auditor, an AI management system being built to ISO/IEC 42001 so it survives the regulator. EU mid-market security teams deserve enterprise-grade NDR without enterprise-grade complexity or cost. That is the company.
