Build vs. Buy: Choosing the Right Path to a CMMC-Compliant IT Environment

Establishing a CMMC enclave is a pivotal decision for defense contractors navigating cybersecurity compliance under CMMC 2.0. Whether you're preparing for a C3PAO assessment or ensuring eligibility for DoD contracts, one question looms large: should you build your own CMMC enclave from scratch or adopt a managed CMMC enclave solution?

The answer depends on four key factors: cost, expertise, time, and risk tolerance.

The Internal Build Approach

Building your own enclave offers full control and customization, but comes with complexity.

High Capital Investment

Internal builds require purchasing and configuring infrastructure aligned to NIST SP 800-171. This includes firewalls, endpoint detection tools, centralized logging, email encryption, and more plus ongoing system maintenance.

Need for Cybersecurity Expertise

To properly build and maintain a compliant environment, you’ll need in-house professionals with deep knowledge of federal cybersecurity frameworks. For many small and mid-sized contractors, hiring cleared experts is expensive and difficult.

Documentation Burden

You’ll be responsible for developing and maintaining your own System Security Plan (SSP), POA&Ms, incident response protocols, and technical configurations. These documents must be accurate and audit-ready.

Long Deployment Timelines

Between procurement, staffing, configuration, and documentation, a DIY CMMC enclave often takes 6–12 months or more to become operational.

The Managed CMMC Enclave Advantage

A managed CMMC enclave, like those offered by Cape Endeavors, dramatically simplifies the path to compliance.

Turnkey, Audit-Ready Infrastructure

Cape Endeavors delivers pre-configured environments purpose-built to meet all 110 NIST SP 800-171 controls—hosted in FedRAMP-authorized cloud environments such as Microsoft GCC High.

Operational & Compliance Support

Managed enclaves include patching, logging, backups, and incident response services—all mapped to CMMC domains. This supports both daily operations and evidence collection for assessments.

Policy Templates and Artifacts

Managed solutions often include built-in policy libraries, mapped controls, and compliance documentation that dramatically reduce internal workload and accelerate certification readiness.

Fast Deployment

Organizations can often onboard and begin operating within a compliant enclave in under 90 days, helping teams get to contract eligibility faster.

Side-by-Side Comparison

Why CMMC Enclaves Matter

CMMC compliance isn't just about checking boxes—it’s about proving to the DoD that your organization can safeguard Controlled Unclassified Information (CUI). Whether you’re a prime or a subcontractor, the environment you choose can either accelerate or delay your certification.

Choosing a CMMC enclave that is purpose-built and actively maintained is often the difference between confidently bidding on contracts or falling short during an assessment.

Final Takeaway

If your organization has the in-house talent, time, and budget to support a full internal build, that may be the right path. But for most, a managed CMMC enclave offers a faster, smarter, and more cost-effective route to certification.
