Evidentiary Custody · Quantum-Resistant
Sensitive data, held to a higher standard of proof.
EpositBox is a quantum-resistant custody platform that protects sensitive records and decision artefacts in a separately governed, immutable environment — so integrity, traceability, and recovery remain defensible under any audit.
The shift in regulatory expectation
From control attestation to evidentiary proof.
Sensitive data is fragmented across applications, vendors, and environments. Supervisors, auditors, and boards are increasingly asking firms to demonstrate — not just attest — that critical records, decisions, and recovery points are authentic, intact, and independently verifiable.
EpositBox is an independent data custody platform that enforces immutable integrity, zero-trust access, and provable audit trails — separating data custody from application logic so integrity, traceability, recoverability, and access discipline are enforced by architecture, not policy alone.
Capabilities
A control model built for the questions your auditors actually ask.
Six pillars that align directly to bank third-party risk reviews and modern resilience frameworks.
Independent Data Custody
Sensitive data lives outside your application database in an independently governed, tamper-evident vault — separating custody from application logic.
Quantum-Resilient Cryptography
Hardware-backed keys via HSM-protected services, with cryptographic agility designed for migration to post-quantum standards.
Zero-Trust, Machine-to-Machine
All access is machine-to-machine; humans never directly access sensitive data stores. No shared credentials. No standing privileges.
Blockchain-Anchored Audit
Every read, write, and delete is permanently logged with deterministic audit trails — a high-integrity corpus for AI behavioural analysis and supervisory review.
Reduced Blast Radius
Your apps and data lakes hold pointers, not regulated values. A breach exposes references, not data.
Defensible Recovery
Versioned, indexed, and independently verifiable — even when primary systems or backups are in doubt.
Built for what's next
AI-Ready by design. Quantum-resilient by architecture.
AI multiplies reliance on high-integrity data. Post-quantum threats challenge the cryptography that protects it. EpositBox addresses both through a single principle: trust must be continuously provable.
AI-Ready by Design
Augmentative, not autonomous. EpositBox provides the immutable, deterministic audit corpus AI needs to be explainable, reviewable, and defensible — supporting anomaly detection, behavioural drift analysis, and compliance evidence generation.

HSM-backed key custody with strict separation from application memory. Cryptographic agility designed for migration to post-quantum standards as they mature — protecting data over decades-long retention horizons.

Architecture that maps to supervisor expectations.
From US examination-driven supervision to prescriptive EU regulation, EpositBox supports the same outcomes regulators ask for: integrity, auditability, recoverability, and accountable AI.
