Organizations face a growing burden when responding to security questionnaires and compliance audits. Traditional workflows rely on email attachments, manual version control, and ad‑hoc trust relationships that expose sensitive evidence. By employing Decentralized Identifiers (DIDs) and Verifiable Credentials (VCs), companies can create a cryptographically secure, privacy‑first channel for sharing evidence. This article explains the core concepts, walks through a practical integration with the Procurize AI platform, and demonstrates how a DID‑based exchange reduces turnaround time, enhances auditability, and preserves confidentiality across vendor ecosystems.
