Microsoft doesn't publicly list GCC High pricing the way it does for commercial Microsoft 365. Licenses are sold through Enterprise Agreements and authorized partners, making it difficult for defense contractors to plan budgets.

As an authorized Microsoft reseller, Secureframe has access to current list pricing for GCC High (and GCC). We created this guide to give you a clear picture of what GCC High actually costs in 2026 and strategies to reduce your spend.

GCC High pricing at a glance

The following are confirmed list prices for authorized resellers as of 2026 for three Microsoft 365 government plans for GCC High. 

Actual prices may vary based on the reseller, Enterprise Agreement terms, commitment length, and more.

The CMMC Level 2 add-ons: What it is & when you need it for GCC High

Only one GCC High license includes all the capabilities required for CMMC Level 2 compliance: that’s the highest enterprise tier, G5.

For Business Premium and G3 licenses, a separate CMMC compliance add-on bundle is required at $24 per user per month. That means if you’re pursuing Level 2, you need to compare the following costs per user per month for each licensing tier:

• Business Premium: Base license $36 + add-on $24 = $60 
• G3: Base license $60 + add-on $24 = $84
• G5: no add-on required since these advanced compliance tools are already included in the base license = $93

For this reason, G5 can be more cost-effective for organizations with higher level CMMC requirements than headline prices suggest.

GCC High vs GCC pricing: Why it’s more expensive

GCC High can be approximately 30% more expensive than Microsoft 365 GCC, depending on the license tier.

Why is it more expensive?

GCC High is a FedRAMP High authorized cloud environment built on Azure Government, a physically separated infrastructure in the U.S. with U.S. support personnel. It’s specifically designed for organizations that handle sensitive government data subject to ITAR, EAR, DFARS, and many other requirements and is explicitly recommended by Microsoft for CMMC Levels 2 and 3.

GCC is another government cloud offering by Microsoft, but it’s built on Azure Commercial and support staff may include non-US persons. That means some services may not meet the strict access controls required for export-controlled data. So while it can support DFARS 7012 and CMMC Level 2 requirements for CUI Basic, it is not suitable for organizations that handle all types of Controlled Unclassified Information (CUI) or are subject to ITAR or EAR regulations. 

GCC High vs Commercial pricing: Why it’s more expensive

GCC High can be approximately 60-70% more expensive than Microsoft 365 Commercial, depending on the license tier. Below are the list prices for the Business Premium and Enterprise licensing plans (G3/G5 are for GCC High and E3/E5 are for Commercial).

Why is it more expensive?

GCC High costs more because Microsoft operates a physically separated cloud infrastructure with:

• Dedicated U.S. data centers on Azure Government
• U.S.-person-only personnel with government-level background checks
• FedRAMP High security compliance and continuous monitoring
• Separate development and operations pipeline

Microsoft 365 Commercial, on the other hand, is built on Azure Commercial, is not FedRAMP authorized, and was not purpose-built to support US government regulations. So while it can be used to demonstrate CMMC Level 1 compliance, it’s not suitable for compliance with DFARS 7012, ITAR, EAR, CMMC Level 2 or Level 3. 

Business Premium: A more affordable option for small contractors

Microsoft launched Microsoft 365 Business Premium for GCC High on November 3, 2025, strategically timed one week before CMMC Phase 1 took effect on November 10, 2025.

Key details

• Base price: $36/user/month
• Price with CMMC Level 2 add-ons: $60/user/month
• Seat limit: up to 300 users
• Includes: Microsoft 365 apps, Intune, Entra ID, Defender for Business, Purview
• Who it is for: Small and mid-sized defense contractors who need GCC High to meet strict security and compliance requirements like CMMC but cannot afford enterprise licensing.
• Not available in GCC

Important caveat: As with other government licensing plans, Business Premium provides a secure environment but does not make you CMMC compliant automatically. You still need proper configuration, a System Security Plan (SSP), and likely consultant engagement.

For a full breakdown of what Business Premium includes, see our GCC High Business Premium guide.

Real-world cost examples for GCC High

Below are cost estimates based on real-world examples of how a defense contractor with 50 people might purchase GCC High licenses to meet CMMC requirements.

Example 1: 50-person contractor, full migration to GCC High G3 with CMMC add-on

These estimates show how much an organization might spend if fully migrating all users to GCC High to meet CMMC Level 2 requirements. A full migration is the most expensive option, and not always necessary. It tends to make sense when most of your revenue is defense-related, most employees routinely touch CUI, or you handle export-controlled ITAR or EAR data that requires stricter infrastructure and access controls.

Example 2: 50-person contractor using Business Premium (GCC High) with CMMC Level 2 add-ons

Business Premium saves approximately $14,400/year compared to G3 in this scenario. The trade-off is fewer advanced compliance features. Evaluate whether the missing enterprise features matter for your specific CMMC controls before committing.

Example 3: 50-person contractor using the enclave approach (10 CUI users)

The enclave approach saves approximately $23,000/year compared to a full 50-user GCC High G3 migration in this scenario. Savings scale significantly with company size.

How to reduce GCC High licensing costs

GCC High costs can be a sticker shock for some organizations, particularly small businesses. Here’s a few proven strategies to save costs so you can benefit from using the only Microsoft-recommended cloud environment for CMMC Level 2 or higher, without breaking the bank.

1. Use the enclave approach

Only employees who directly handle CUI need GCC High licenses. Isolate CUI into a defined boundary and keep everyone else on commercial Microsoft 365. This can reduce license costs by 50 to 80% depending on what share of your users actually touch CUI.

2. Consider GCC if your contracts allow it

GCC High is not always required for CMMC compliance. If your contracts do not reference ITAR, EAR, or DFARS 252.204-7012, GCC may be sufficient and saves $16/user/month on G3. 

See our GCC vs GCC High guide and confirm with your contracting officer before making this decision.

3. Choose Business Premium for organizations under 300 seats

Starting at $36/user/month versus $60 for G3 and $93 for G5, Business Premium can offer cost savings ranging from 30% to 60% for eligible organizations, depending on the CMMC level and add-ons required. 

See our Business Premium guide and confirm eligibility to see if this plan is available to your organization.

4. Evaluate whether G5 is more cost-effective than G3 with the add-on

In GCC High, G3 plus the CMMC add-on totals $84/user/month versus $93 for G5. The gap is only $9/user/month, and G5 includes additional security and compliance capabilities that may reduce your need for other point solutions. Run the numbers for your specific environment.

5. Negotiate your Enterprise Agreement

GCC High pricing is negotiable, especially for multi-year commitments or large seat counts. Consider evaluating multiple AOS-G partners to compare quotes before signing. As an authorized GCC High reseller, Secureframe is committed to offering the lowest pricing on the market.

How to purchase GCC High licenses

GCC High licenses are not available through Microsoft's standard online portal. The purchasing process depends on your organization's size.

• Organizations under 300 seats: You must work with a Microsoft AOS-G (Agreement for Online Services - Government) authorized partner. These partners are specifically approved by Microsoft to sell GCC High. Not all Microsoft partners qualify.
• Organizations with 300 or more seats: You can purchase through an LSP (Licensing Solution Provider) via a standard Enterprise Agreement, or through an AOS-G partner.

The purchasing process

The purchasing process is broken down into four key steps:

1. Eligibility verification: Provide your CAGE code or proof of government data handling
2. Partner engagement: Select an AOS-G partner such as Summit 7, Agile IT, or ECF Data
3. License procurement: Typically 2 to 10 business days after eligibility approval
4. Tenant provisioning: Up to 30 days per Microsoft SLA for a new GCC High tenant

Upcoming price changes for enterprise government plans for GCC High

Microsoft has announced price increases for government licenses effective July 1, 2026. 

While exact July 2026 list prices for G3 and G5 for GCC High have not been confirmed at time of publication, the estimates below are based on confirmed list prices from AOS-G resellers and percentage increases from Microsoft. So factor expected increases into 2026 to 2027 budget planning.

Since Business Premium is not increasing, it is an even more cost-effective option relative to the enterprise G-series SKUs.
