42Crunch: sovereignty score and 8 European alternatives

42Crunch is a security platform for APIs and MCP servers. It discovers and inventories MCP servers, scores them against the OWASP MCP Top 10, and tests APIs with static and dynamic checks based on the OWASP API Top 10. It can also enforce contract-based gates in CI/CD pipelines and block undeclared API traffic at runtime. Findings are mapped to frameworks such as the NIST AI RMF, the EU AI Act and ISO/IEC 42001. The service is offered as a cloud platform, and enterprises can obtain a dedicated platform instance.

42Crunch Ltd is headquartered in London, United Kingdom. The company is venture-funded. Where the shared platform is hosted is not published. The United Kingdom is outside the EU but operates its own GDPR-based regime. European organisations that entrust API definitions and test results to an external service should have the hosting region and processing terms confirmed in advance.

Why digital sovereignty matters with 42Crunch

42Crunch 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.

42Crunch hosts data outside the EU (OTHER). Personal data therefore leaves the EU, which requires a transfer mechanism under the GDPR and pulls the data residency score down.

42Crunch 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 42Crunch together with your other vendors and gives a total score, a heatmap and the main risk drivers.
