Hack The Box: sovereignty score and 6 European alternatives

Hack The Box is an online platform for cybersecurity training and for measuring the skills of security professionals. Its offering includes hands-on labs, an Academy with courses and learning paths, capture-the-flag competitions, team exercises such as Threat Range, tabletop-style incident response exercises and a service for finding security talent. The company targets businesses that want to train and assess their security teams. The platform is delivered as an online service and is not open source. The company was founded in 2017.

The contracting party is Hack The Box Ltd, a British company with a registered address in Folkestone, Kent. Its headquarters is therefore in the United Kingdom, outside the EU. The sources consulted show no separate parent company outside that structure. Where user data is stored exactly could not be established from the sources consulted. A European organisation using the platform for staff training would therefore do well to request the data processing agreement and the list of sub-processors.

Why digital sovereignty matters with Hack The Box

Hack The Box is headquartered in GB, outside the EU. Contracts and data therefore also fall under non-European law. The GDPR applies through contractual terms, but in a conflict with local legislation you have less certainty than with a European vendor.

Data is hosted exclusively in the EU, so Hack The Box scores best on data residency.

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