Introduction

Before You Buy GCC High, Make Sure You Actually Need It

Microsoft Commercial, GCC, and GCC High serve different needs, and CMMC Level 2 does not automatically mean your organization needs GCC High.

In this webinar, Anthony Buono and Larry Robertson of Charles IT break down what government and defense contractors should understand before choosing an environment. They cover how CUI, ITAR, DFARS requirements, CMMC Level 2, licensing, security controls, and migration requirements can affect the decision.

You’ll also learn what to evaluate before requesting a GCC High quote, how G3 and G5 licensing can align with different users and CUI boundaries, and why purchasing GCC High alone does not make an organization CMMC compliant.

Find the Right Microsoft Environment for Your Business

Choosing between Microsoft Commercial, GCC, and GCC High should start with understanding your contracts, data, users, devices, CUI boundary, security architecture, compliance requirements, and future business needs. Charles IT can help you evaluate your requirements and build a roadmap for licensing, migration, security, and CMMC readiness.

Does CMMC Level 2 require GCC High?

Not automatically. Whether GCC High is appropriate depends on factors such as the information your organization handles, contractual requirements, CUI, ITAR, and the security requirements that apply to your environment.

Microsoft Commercial, GCC, and GCC High are different Microsoft cloud environments. Which environment makes sense depends on your organization’s data, contracts, users, security needs, and applicable requirements.

No. GCC High is only one part of the overall environment. CMMC readiness also involves security controls, policies, endpoints, logging, evidence, SSPs, POA&Ms, and other requirements.

Consider your contracts, CUI and ITAR requirements, users, devices, CUI boundary, security architecture, licensing needs, and future business requirements before choosing an environment.

Migration planning can involve licensing, users, data, devices, security controls, and your existing Microsoft environment. These factors should be evaluated before beginning the migration.

The webinar discusses G3 and G5 in the context of matching licensing to user roles and CUI boundaries rather than assuming every user requires the same licensing.
