CMMC Level 2: Do You Really Need GCC High? When Microsoft GCC or Google Workspace Is the Smarter Choice

CMMC Level 2: Do You Really Need GCC High? When Microsoft GCC or Google Workspace Is the Smarter Choice

Published by C-LevelCyber LLC | May 2025

If your company is preparing for CMMC Level 2 certification, you’ve likely heard the same advice over and over:

“You need Microsoft GCC High to be compliant.”

But here’s the truth: Unless you are subject to ITAR (International Traffic in Arms Regulations), you probably don’t.

Let’s break it down simply:

Start With This One Question:

Top Authoritative & Official CMMC Resources:

These are trusted by compliance officers, IT leads, and business decision-makers:

1. CyberAB.org (The Cyber Accreditation Body)

• Most official resource for RPOs, C3PAOs, and certified assessors.
• Directories of authorized/certified providers
• Regular updates on rulemaking and training

2. DoD CMMC Program Page

• Office of the DoD CIO – official details on model versions, timelines, and rulemaking.
• Updates on the DFARS 252.204-7020/-7021 implementation

3. NIST.gov

• For referencing NIST 800-171 and 800-172 which underlie CMMC Levels 2 and 3.

Top Industry Watchdog & Comprehensive Market Tracker

4. CMMCMarket.com

Most comprehensive global listing of:
