PMXChain

Data integrity for Microsoft 365

PMXChain extends Microsoft 365 with a cryptographically secured trust layer, making business-critical documents tamper-proof, revision-capable, and verifiable at any time. Organizations gain complete transparency into data access, changes, and lifecycles – without additional infrastructure or complex security systems.

Through blockchain-based integrity proofs, Zero-Knowledge, and native integration into Microsoft 365 (OneDrive/SharePoint), a secure foundation for compliance, audit, and governance is established.

Complete transparency secures every step in the document lifecycle

Challenges & Solution

Secure Data Integrity and Audits

Microsoft 365 protects access and identities, but not the continuous integrity of documents throughout their entire lifecycle. This results in key challenges:

  • Lack of proof of data integrity
  • Limited auditability of document changes
  • Dependency on cloud providers for encryption
  • Rising regulatory requirements
  • High effort for compliance proofs

Trust in PMXChain

Security & Governance are today among the central concerns of organizations, particularly in regulated industries. It must be ensured that confidential content is protected from access by external service providers and that immutable, traceable documentation exists.

The PMXChain integration in SharePoint demonstrates how this can be achieved:

Through cryptographic signatures, blockchain anchoring, and audit-proof audit logs, the immutability principle is technically implemented – precisely where teams today store and collaboratively edit documents.

As a specialist in digital work environments, MondayCoffee – and I, personally, as a sparring partner – accompany PMXChain in developing its solution.

We are convinced that it hits the nerve of the times and has the potential to become a real game changer for even more secure collaboration in Microsoft 365.
