Built in Alicante for the EU mid-market.
TriStiX S.L. is a cybersecurity company in Alicante, Spain, that builds NetSenX. NetSenX is a Network Detection and Response (NDR) platform for EU mid-market organisations that detects attacks from network behaviour, explains every alert in plain language and keeps customer data in the EU. We exist because EU mid-market security teams need network detection they can afford, understand and defend in an audit, without the complexity of tools built for large security operations centres.
Mission
Cyber-resilient EU companies, without the alert factory.
Make EU companies cyber-resilient through detection with a stated false-positive bound, AI-assisted response and compliance evidence that holds up in an audit, without giving up privacy, sovereignty or budget.
We treat three things as non-negotiable: a conformal layer that states the false-positive bound a customer's own calibration data supports, and withholds a figure when it supports none (the NetSenX Math Guarantee); customer data kept in the EU under EU rules; and a published price a mid-market CFO can defend. Everything else in the product serves those three.

EU mid-market security teams see the same pattern repeat: the detection stack gets louder every quarter, the budget tighter every year, and the alert backlog grows faster than any small team can work through it. 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 false-positive bound comes from split-conformal prediction, a published statistical method, applied to benign traffic your own analysts have labelled: it is derived, not tuned. How tight it is on your network depends on how much labelled traffic has been calibrated, which is why the product shows the bound your data supports and says plainly when it does not support one yet.
The rest of NetSenX makes that operational: an AI Analyst Core that writes the analyst notes, an audit log that survives the auditor, and an AI management system being built to ISO/IEC 42001 so that it survives the regulator. EU mid-market security teams deserve network detection they can afford and explain. That is the company.
What we are building next
- SOC 2, ISO/IEC 42001 and ISO/IEC 27001 — in preparation; dates follow once audits are booked.
- An EIC Accelerator application in Q4 2026 to scale the EU mid-market go-to-market.
- First engineering and customer-success hires, in Alicante and remote across the EU.

Operating principles
Three rules. No exceptions.
01
Math before marketing
Every detection claim rests on a stated method. If we cannot back a bound with your data, we do not put a number on a slide.
02
Sovereign by design
Customer data is stored in the EU and handled under EU law, in the language of the customer. Where a sub-processor sits outside the EU, the data processing agreement names it and the safeguard it relies on.
03
Audit first
Compliance is part of the product, not friction. The evidence pack exists before the sales pitch does.
