Blotout: sovereignty score and 8 European alternatives

Blotout provides managed signal infrastructure for direct-to-consumer brands and the agencies that work for them. The offering covers signals and measurement, agency software, support and governance. Products include EdgeTag, a first-party data infrastructure for server-side tracking, and Consent for region-based consent management. According to the company, EdgeTag runs on Cloudflare Workers at the network edge.

Blotout, Inc. is a US company; its privacy policy says the services are hosted in the United States and that information is stored and processed on US servers. For transfers from the EEA, the UK and Switzerland the policy refers to Standard Contractual Clauses or consent. The website lists GDPR support and region-aware enforcement for the EU and UK, and states that no personal data is required to operate the service; a data processing agreement should be requested separately. For a European organisation this means measurement data sits with a US provider, with exposure to the CLOUD Act. The software is not open source.

Why digital sovereignty matters with Blotout

Blotout 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.

Blotout 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.

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