Certanix uses AI to test AI: it stress-tests drones, robots and other autonomous AI systems across thousands of simulated scenarios, for civil and defence use alike. Every result is sealed in a cryptographically signed evidence pack that anyone can verify offline, even inside an air-gapped defence environment, with no need to trust the maker. EU-sovereign deep tech built in Luxembourg, ready for quantum hardware, and backed by two European patent applications: verify before you deploy.
