Lumia Security: sovereignty score and 8 European alternatives

Lumia Security sells an AI usage control platform that gives enterprises visibility into, and enforcement over, how employees and AI agents use AI tools. According to its website, the platform operates at the network layer and can be integrated into existing network infrastructure or deployed as a standalone proxy. Listed capabilities include shadow AI analysis, prevention of data leakage, agent guardrails, coding-assistant security and MCP visibility. The website does not state whether the service is vendor-hosted or deployed by the customer.

The website gives a New York address, and SecurityWeek describes the company as headquartered in New York and Tel Aviv, Israel. It was founded in 2024. The public pages do not state where customer data is hosted and give no GDPR or data processing commitment. For a European organisation, the relevant points are the company's US and Israeli presence, the path that traffic and logs take through the proxy, and whether a data processing agreement with EU safeguards is available before deployment.

Why digital sovereignty matters with Lumia Security

Lumia Security 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.

Lumia Security 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.

Lumia Security 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 Lumia Security together with your other vendors and gives a total score, a heatmap and the main risk drivers.
