CaptchaFox: sovereignty score and 8 European alternatives

CaptchaFox is a CAPTCHA and bot-protection service that aims to block spam, fake sign-ups and account takeover on forms and logins. When a visitor interacts with a protected form, bot detection, proof-of-work and threat intelligence run in the background: humans pass through, while suspected bots are slowed down and given a risk score. The vendor says its API is compatible with reCAPTCHA and hCaptcha, so migrating may only require swapping the script and keys. SDKs cover React, Vue, Angular, WordPress, JavaScript and Keycloak, and a dashboard lets administrators adjust protection without coding. It is delivered as hosted SaaS.

CaptchaFox is provided by Scoria Labs GmbH, a German company based in Hallbergmoos. The vendor states that processing takes place exclusively in EU data centres with no transfers to third countries, that it acts as a processor under Article 28 GDPR with a data processing agreement available, and that it uses no cookies or trackers. The hosting providers are not named publicly, but the sub-processor list can be requested from the vendor.

Why digital sovereignty matters with CaptchaFox

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

Data is hosted exclusively in the EU, so CaptchaFox scores best on data residency.

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