NetSenX as a Nozomi Networks alternative for OT
Nozomi Networks is an OT and IoT security specialist for industrial and critical-infrastructure estates. NetSenX covers IT and common industrial protocols in one NDR, priced for mid-sized sites.
At a glance
| Aspect | NetSenX | Nozomi Networks |
|---|---|---|
| Focus | Behavioural NDR for EU mid-market organisations: a plain-language explanation on every alert, a conformal false-positive bound once your own data supports it, NIS2 Article 23 deadline tracking. | OT and IoT visibility for industrial and critical-infrastructure networks: asset inventory, vulnerability analysis and threat and anomaly detection. |
| Published pricing | Yes. Free plan; Starter €49 to Business €249 per month; Enterprise from €999 per month (excluding VAT). | No public price list; the SaaS licence is priced by the number of monitored assets and quoted per environment. |
| Deployment | EU-hosted dashboard (SaaS). One agent on a SPAN/TAP port per network segment, or on the hosts you choose (Linux, macOS, Windows). On-premises on the Enterprise plan. | Guardian sensors (hardware, virtual machine, embedded or container) on mirrored ports or taps, managed centrally through the Vantage SaaS platform. |
| Where data is kept | Database in Ireland (AWS eu-west-1), API in Frankfurt, Germany. | Sensors keep traffic on site; ask the vendor where Vantage SaaS data is hosted. Nozomi Networks has been a subsidiary of Mitsubishi Electric since January 2026, with an R&D hub in Switzerland. |
| OT / industrial networks | From the Pro plan: Modbus/TCP, DNP3, BACnet/IP, EtherNet/IP and S7comm read passively; OT devices are never actively probed. | Core focus, with published mappings to NIS2 and IEC 62443. |
Where Nozomi Networks is strong
- OT and IoT specialisation, with detailed asset inventory and vulnerability analysis.
- Sensors as hardware appliances, virtual machines, embedded devices or containers.
- Published compliance mappings for NIS2 and IEC 62443.
Where NetSenX fits
- You run a mid-sized site where IT and OT share one small team, and want both in one NDR.
- The common industrial protocols — Modbus/TCP, DNP3, BACnet/IP, EtherNet/IP, S7comm — are enough, read passively from the Pro plan.
- You want published prices, EU data residency and NIS2 Article 23 deadline tracking per incident.
Before you decide
NetSenX is a young company: SOC 2 Type I and ISO/IEC 42001 are in preparation, not attested. NetSenX is not an OT asset-management platform; for large, multi-site industrial estates that need detailed OT asset inventory and vulnerability analysis, Nozomi Networks covers more ground.
Questions buyers ask
Can NetSenX replace Nozomi Networks for OT monitoring?
It depends on scale. From the Pro plan, NetSenX reads five common industrial protocols passively and covers IT traffic in the same product. Large multi-site industrial estates that need a dedicated OT asset inventory and vulnerability management are the core use case of Nozomi Networks.
Does NetSenX actively probe PLCs or SCADA devices?
No. Devices classified as OT are never actively probed; NetSenX reads industrial protocols from passive capture on a SPAN or TAP port only.
