DataDome: sovereignty score and 8 European alternatives

DataDome provides bot and agent trust management for websites, mobile apps and APIs. It aims to stop scraping, credential stuffing, account takeover and fraud before requests reach the origin servers. Its Slider is presented as an alternative to puzzle-based CAPTCHAs: according to the vendor, low-risk visitors are verified invisibly, riskier traffic gets a short swipe challenge, and confirmed malicious traffic is blocked. DataDome is delivered as SaaS and can be deployed server-side, client-side or through third-party tools, with many ready-made integrations, including several CDNs.

DataDome is headquartered in Paris, with New York also named as a headquarters, and InfraVia has been an investor since 2023. Detection runs on regional API endpoints worldwide, including Germany, France, Ireland and the UK in Europe, as well as North America and Asia Pacific. By default, traffic is routed to the nearest endpoint, although customers can choose a specific country. Since this routing is not limited to the EU, European organisations should check the data processing agreement and sub-processors for where data is processed.

Why digital sovereignty matters with DataDome

DataDome is headquartered in FR and therefore falls under European law: the GDPR, NIS2 and the Data Act. No foreign legislation can compel access to your data.

DataDome hosts data in EU, US, OTHER. Exactly what stays within the EU — and what does not — is defined by the vendor's data processing agreement and sub-processor list, not by a setting you control yourself; check those documents for the precise scope, including backups, logs and support access.

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