RESULT

▫️Unauthorized access attempts: Down 99.9% with zero-trust enforcement
▫️ Document access time: Reduced by 40% via streaming + caching
▫️ GDPR & ISO 27001 audits: Passed with zero security issues
▫️ 100% of sensitive data encrypted in transit & at rest — no server-side keys, ever
▫️ Immutable audit trails — backed by Merkle chains and optional private blockchain

THE CLIENT

    • A confidential financial services conglomerate operating across Germany, France, and the Netherlands — with strict regulatory requirements and high-stakes data handling needs.

THE PROBLEM

  • ▫️Their document systems weren’t built for modern security. Sensitive financial and legal files were scattered, exposed, and slow to access.
  • ▫️Access control was inconsistent, and insider threats were rising.
  • ▫️Compliance audits were a fire drill every quarter.
  • ▫️No cryptographic guarantees for multi-party workflows.
  • ▫️Legacy infra couldn’t support zero-trust or immutable logging.

OUR SOLUTION

  • We built a zero-trust document vault from scratch in Rust — combining encrypted storage, zero-knowledge access control, and blockchain-backed audit logging.

    Key Systems We Integrated:
    ▫️ Rust-native encryption (age, ring) for client-side file protection
    ▫️ arkworks-rs for zero-knowledge membership proofs
    ▫️ Merkle-tree logging with optional Substrate or Hyperledger support
    ▫️ Multi-party access control via cryptographic signatures
    ▫️ Fully modular, blockchain-ready architecture

BOTTOM LINE

  • ▫️We helped this financial powerhouse turn compliance chaos into cryptographic certainty — and delivered a vault that actually earns the name.
  • ▫️No backdoors. No bottlenecks. Just bulletproof privacy and performance, by design.
