Nozomi Networks: sovereignty score and 8 European alternatives

Nozomi Networks provides network visibility, asset discovery and threat detection for operational technology (OT) and Internet of Things (IoT) environments. Its platform includes sensors that monitor industrial networks, an endpoint component and a cloud product called Vantage. Customers who want monitoring to stay inside their own network can run the Central Management Console on-premises. The company is Nozomi Networks Inc. and is described as California-based.

Since Japan's Mitsubishi Electric completed its acquisition of the company in 2026, Nozomi Networks has been owned by a non-European group. A US provider can be compelled under the CLOUD Act to disclose data it controls, wherever its servers are located, and this includes the cloud services. The vendor's public pages name no European hosting location, and the products are not presented as open source. A European organisation keeps the most control by using the on-premises components and by reviewing processing terms before deployment.

Why digital sovereignty matters with Nozomi Networks

Nozomi Networks is headquartered in the United States. US vendors fall under the CLOUD Act and FISA 702: US authorities can compel access to data, even when that data sits in a European data centre. That is the core of the jurisdictional exposure in our model. The ultimate owner is based in JP. Foreign control undermines part of the certainty a European headquarters offers.

Nozomi Networks hosts data outside the EU (US). Personal data therefore leaves the EU, which requires a transfer mechanism under the GDPR and pulls the data residency score down.

Nozomi Networks is closed source and hosted by the vendor. The encryption keys and the runtime sit with the vendor and switching requires data migration. Ask about bring-your-own-key, export options and open standards.

What this means for your organisation depends on your whole stack and context. The free assessment weighs Nozomi Networks together with your other vendors and gives a total score, a heatmap and the main risk drivers.
