gcch enclave

Executive Summary

One of the first questions organizations ask when pursuing CMMC Level 2 certification is:

“Who should build our GCC High enclave?”

Most organizations consider three options:

• Build internally
• Hire a traditional CMMC consultant
• Partner with a Managed Security Services Provider (MSSP)

The right answer depends on your organization’s technical expertise, available resources, compliance maturity, and long-term operational requirements.

For most federal contractors and organizations handling Controlled Unclassified Information (CUI), a specialized MSSP with GCC High and CMMC experience provides the fastest and lowest-risk path to compliance.

Why GCC High Enclaves Are Different

Building a GCC High enclave is not the same as deploying Microsoft 365.

A compliant enclave requires:

• Secure architecture design
• Identity and access management
• Endpoint security
• Data protection controls
• Audit logging
• Incident response capabilities
• Vulnerability management
• Continuous monitoring
• Documentation and evidence collection

Success requires expertise in both Microsoft technologies and compliance frameworks such as:

• CMMC Level 2
• NIST SP 800-171
• DFARS 252.204-7012
• CJIS Security Policy
• Critical infrastructure security requirements

Option 1: Build the Enclave Internally

Some organizations attempt to design and deploy the enclave using their internal IT staff.

Advantages

• Direct control over implementation
• Internal knowledge retention
• No external dependency

Challenges

Most IT teams have extensive experience supporting users and infrastructure but limited experience designing environments specifically for CMMC assessments.

Common obstacles include:

• Limited GCC High experience
• Lack of familiarity with assessment requirements
• Documentation gaps
• Resource constraints
• Delayed implementation timelines

Organizations often underestimate the amount of work required to maintain compliance after deployment.

Option 2: Hire a Traditional CMMC Consultant

Traditional consultants focus primarily on compliance readiness.

They typically assist with:

• Gap assessments
• Policies and procedures
• SSP development
• POA&M creation
• Assessment preparation

Advantages

• Strong compliance expertise
• Assessment guidance
• Documentation support

Challenges

Many consultants do not actually build the enclave.

Organizations frequently discover they still need internal staff or another provider to:

• Configure GCC High
• Implement security controls
• Manage devices
• Monitor logs
• Maintain compliance

This can result in multiple vendors and increased project complexity.

Option 3: Partner with a Specialized MSSP

A specialized MSSP combines compliance expertise with operational execution.

Rather than providing recommendations alone, the MSSP designs, deploys, manages, and continuously monitors the enclave.

Advantages

• Single accountability model
• Faster deployment
• Reduced compliance risk
• Ongoing monitoring
• Long-term support

The MSSP becomes an extension of the internal IT team.

What IT Directors Should Evaluate

When selecting a provider, IT Directors should ask:

Do They Understand CMMC?

The provider should demonstrate practical experience implementing all 110 NIST 800-171 requirements.

Do They Specialize in GCC High?

Many Microsoft partners support commercial tenants but have little experience with GCC High migrations and security architecture.

Do They Provide Ongoing Support?

Compliance does not end after deployment.

The provider should offer:

• Continuous monitoring
• Vulnerability management
• Incident response support
• Compliance validation

Can They Support the Assessment Process?

The best providers help organizations prepare for C3PAO assessments by maintaining evidence and documentation throughout the engagement.
