SENTRY — SOC for Defense Contractors

SOC Monitoring Built for the Defense Industrial Base

Defense contractors handling Controlled Unclassified Information (CUI) need monitoring that maps directly to CMMC 2.0 and NIST 800-171 requirements — not a generic SOC with compliance language added to the sales deck.

What CMMC-Aware Monitoring Means

Monitoring Mapped to CUI and NIST 800-171

CMMC 2.0 is built on NIST SP 800-171’s security requirements. A SOC serving defense contractors needs its detection and logging scoped specifically around where CUI lives and moves — not just running default detection content against a generic IT environment.

CUI-scoped monitoring

Detection and log collection prioritized around systems and data flows that handle Controlled Unclassified Information, aligned to the boundary defined in your System Security Plan (SSP).

NIST 800-171 control mapping

Continuous monitoring generates evidence directly against relevant NIST 800-171 control families rather than requiring a separate manual compilation before an assessment. See our NIST 800-171 vs. CMMC crosswalk for how the frameworks relate.

Assessment-ready evidence

Documentation and logging practices built with a C3PAO assessment in mind from day one, not reconstructed under deadline pressure before certification.

Level-appropriate scope

Monitoring scope calibrated to whether your CMMC target is Level 1 or Level 2 — see our CMMC Level 2 vs. Level 3 breakdown for how requirements escalate.

Governance and Monitoring, One Program

Getting to a CMMC 2.0 assessment involves both governance work (SSP, POA&M, control implementation) and ongoing monitoring evidence. Armorstack runs CMMC readiness through VERITY and continuous monitoring through SENTRY as one converged program instead of two vendors that don’t talk to each other. See the full Armorstack CMMC 2.0 compliance page for the governance side of this work.

Frequently Asked Questions

Does this satisfy the CMMC 2.0 continuous monitoring expectation?
A properly scoped SOC engagement is built to generate the ongoing monitoring evidence your C3PAO assessor will expect — but final certification depends on your full program, not monitoring alone. See our CMMC compliance page for the complete picture.
Do you work with cleared or CUI-restricted environments?
Scope and handling requirements for CUI-restricted environments need to be discussed directly — reach out to scope your specific environment and its data-handling constraints.
How is this different from generic MDR?
Generic MDR isn’t scoped around CUI boundaries or mapped to NIST 800-171 control families by default. See our general MDR vs. MSSP page for the underlying service distinction, then layer the CMMC-specific scoping on top.
