Exostar CMMC Ready Suite vs MNS Group BUILT SecureCMMC: Side-by-Side Comparison (2026)

Exostar CMMC Ready Suite

Mid-market and enterprise Defense Industrial Base contractors need CMMC Level 2 readiness without rebuilding their security program from scratch, and Exostar CMMC Ready Suite cuts implementation time by handling all 110 NIST SP 800-171 controls plus the documentation overhead that kills most projects. The CUI-isolation secure enclave separates sensitive data from corporate networks by design rather than policy, which is why their assessment support actually closes control gaps instead of just identifying them. Skip this if your organization runs highly distributed or air-gapped networks where hybrid deployment becomes a liability, or if you need the deep forensics and continuous monitoring that NIST Detect functions require; Exostar prioritizes readiness and evidence collection over detection and response.

MNS Group BUILT SecureCMMC

Architecture and engineering firms pursuing CMMC Level 2 certification should choose MNS Group BUILT SecureCMMC because it bakes compliance directly into the workspace rather than bolting it on afterward. The platform delivers a Google Workspace-native enclave with Zero Trust segmentation, customer-owned tenancy, and C3PAO-backed training, meaning your audit trail stays yours and your team gets certified guidance from day one. This is overkill for firms that haven't won a defense contract yet or are still evaluating whether CMMC is actually mandatory for their subcontractor status.
