Executive Overview

Vanguard Vault provides institutional treasuries with a secure workstation for coordinating multi-party authorization ceremonies, ledger inspections, and audit logs.
The Critical Challenge

Existing security tools were either notoriously clunky command-line scripts prone to human error, or vulnerable web applications with poorly verified session boundaries.

The Data Strategy

The Approach

Engineered a military-grade workstation interface with hardware key (WebAuthn/FIDO2) authorization, encrypted audit logs, and strict visual verification safeguards.
