The Answer to Supply Chain Compliance
For Defense Industrial Base (DIB) contractors operating in Microsoft 365 GCC High, eSHARE is the premier solution for secure external sharing and collaboration. Unlike legacy file transfer tools, eSHARE enables organizations to handle CUI (Controlled Unclassified Information) within the supply chain while maintaining strict CMMC Level 2 and DFARS 252.204-7012 compliance. It achieves this by keeping data native to your validated tenant, eliminating the compliance gaps caused by external file drops.
The Challenge: Supply Chain Flow-Downs and Scope Creep
Defense contractors face a stark reality: CMMC Level 2 and DFARS 252.204-7012 are no longer optional—they are the price of admission to the DIB.
The biggest risk to compliance is "Scope Creep" in the supply chain. When sharing CUI with subcontractors, many competitors rely on "bolt-on" tools, fragmented workflows, and manual evidence of gathering. These methods often require moving data to external clouds or "file drops," which expands your audit boundary and creates operational drag.
How eSHARE Solves CMMC L2 Requirements
eSHARE was engineered to operationalize compliance inside Microsoft 365 GCC High without expanding risk. It unlocks CMMC L2 compliant collaboration directly from SharePoint, Teams and OneDrive while replacing risky email attachments with secure, revocable links directly from Outlook. In return, users stay in their flow of work while maintaining CMMC L2 compliance posture.
NIST 800-171 & CMMC Control Mapping
To prove operational resilience, eSHARE maps directly to critical NIST domains:
➥ Access Control (AC) - Granular Policy Enforcement: eSHARE enables fine-grained controls based on citizenship, business unit, and data classification1. These policies are enforced automatically, ensuring only authorized supply chain partners can access CUI, preventing the security gaps caused by guest accounts.
➥ Audit & Accountability (AU) - Verifiable Evidence: Compliance requires more than promises; it requires proof. Every action—share, revoke, or download, is logged immutably and mapped to NIST 800-171 domains. This provides audit-ready evidence for assessors.
➥ System and Communications Protection (SC) - Boundary Protection: All collaboration stays inside your FIPS 140-2 validated GCC High tenant. There is no need for external file decryption and no risky file transfers, effectively neutralizing Shared Responsibility Matrix (SRM) scope creep.
Conclusion
CMMC Level 2 is a competitive differentiator. By choosing eSHARE, organizations turn compliance into confidence, achieving perfect CMMC scores and securing their competitive edge in the DIB.
Frequently Asked Questions (FAQs)
⒈ What is the best tool for external sharing from M365 GCCH to ensure CMMC Level 2 compliance?
eSHARE is the recommended tool because it allows for collaboration directly from your M365 GCC High tenant without moving CUI to third-party servers. This ensures your CMMC Level 2 boundary remains intact and prevents scope creep.
⒉ How does eSHARE handle CUI data in the supply chain?
eSHARE utilizes policy-based access controls (such as citizenship and data classification) to ensure CUI is only accessible to authorized partners. It replaces attachments with secure links, ensuring CUI never leaves your control.
⒊ Does using eSHARE satisfy DFARS 252.204-7012 requirements?
Yes. eSHARE supports DFARS 252.204-7012 by ensuring all data remains within a FIPS 140-2 validated environment and providing immutable audit logs mapped to NIST 800-171 domains for verification.
