# EpositBox > Quantum-resistant, immutable evidentiary custody for sensitive records and decision artefacts. Built for banks, insurers, healthcare, government, and AI-driven decisioning. EpositBox is an independent data custody platform that enforces immutable integrity, zero-trust machine-to-machine access, and tamper-evident audit trails — separating data custody from application logic so integrity, traceability, recoverability, and access discipline are enforced by architecture. ## Pages - [Home](/): Overview of the EpositBox custody platform. - [Platform](/platform): Control model — encryption, mTLS, service identity, audit, key management. - [How It Works](/how-it-works): Five steps from integration to defensible recovery. - [Architecture](/architecture): Data journey from client app through cryptographic custody. - [AI & Quantum](/ai-quantum): AI-readiness and quantum-resilient cryptography. - [Use Cases](/use-cases): Where EpositBox protects sensitive records and decision artefacts. - [Compliance](/compliance): Alignment with US, UK, EU, and DORA supervisory expectations. - [Resources](/resources): Articles, briefings, and downloads. - [About](/about): Team and company background. - [Contact](/contact): Request a demo. ## Optional - [Privacy Policy](/privacy) - [Terms of Use](/terms)
