Kasada: sovereignty score and 8 European alternatives

Kasada is a bot-mitigation and fraud-prevention platform for websites and APIs. The company names Bot Defense, which stops sophisticated bots without CAPTCHAs, Account Intelligence for human-driven fraud, AI Agent Trust to govern which AI agents may access resources, and Kasada IQ for Fraud as components. Typical uses include account takeover, scraping, guest-checkout fraud, SMS toll fraud and promotion abuse. In technical write-ups Kasada describes a combination of client-application fingerprinting through JavaScript inspection and a cryptographic proof-of-work challenge whose difficulty rises with request volume. Protection operates at the edge; the homepage does not describe a precise delivery model.

Kasada says it operates from offices in New York and Sydney, as well as Boston and San Francisco, among others; sources do not give a consistent headquarters. The software is not open source. The pages consulted give no information on where customer data is hosted, so European organisations with data-residency requirements should ask Kasada directly.

Why digital sovereignty matters with Kasada

Kasada 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.

Kasada hosts data in US, EU, APAC. 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.

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