One partner for the three things a DoD contractor has to get right: proving compliance against NIST SP 800-171 and CMMC 2.0, running the day-to-day security operations that satisfy the controls, and standing up the Microsoft cloud where your CUI actually lives. Engagements are modular — take the whole program or just the piece you are missing.
A C3PAO assessor does not grade intentions; they grade artifacts. Every offering below is delivered so that it continuously generates the audit logs, policy documents, configuration baselines, and status reports an assessor expects to review — the difference between "we do that" and "here is the evidence that we do that."
One line of scope, stated plainly: Atom is a managed security and compliance provider, not a C3PAO. We prepare you for, and help you sustain, a certification assessment. We do not perform the official assessment itself — that independence is the point.
The compliance work that gets you to an assessment and keeps you there: gap analysis, documentation, remediation, and the governance that runs the program between audits.
A full gap assessment against your target level, the SSP and POA&M to document it, and hands-on remediation of the findings — so you walk into a C3PAO assessment ready to pass, not hoping to.
Ongoing governance, risk, and policy management plus fractional security leadership — the connective tissue that keeps the whole program pointed at the controls that matter between assessments and annual affirmations.
A NIST SP 800-171 gap analysis scored with the DoD Assessment Methodology, so you can report an honest, defensible SPRS score before a prime asks for it.
End-to-end alignment and documentation to NIST SP 800-171/172 and the DFARS clauses your contracts flow down — the framework work behind a clean assessment.

The day-to-day security and IT operations that satisfy the technical control families and produce the artifacts an assessor asks to see.
A ticketed service desk backed by 24/7 remote monitoring & management (RMM) — endpoint management, patching, and automation — plus living documentation and runbooks, operated and stored inside your GCC High enclave rather than a commercial cloud. A stable, documented baseline the rest of the program builds on.
24x7 US-based SOC monitoring and human-led response. When something moves in your environment, a defender is already watching it — and logging it.
Behavioral endpoint defense across your fleet, with detections, timelines, and containment actions retained for review.
Audit & Accountability Incident Response System & Information Integrity
Zero-trust MFA and device trust, so access to CUI systems depends on a verified user and a healthy, known device — not just a password.
Access Control Identification & Authentication
Continuous monitoring of Microsoft 365 and Entra ID identities to detect and stop account takeover, business email compromise (BEC), and token/session theft — auto-containing malicious inbox rules and rogue OAuth grants, with retained forensics across Entra ID, Exchange, and SharePoint.
Identification & Authentication Access Control Incident Response System & Information Integrity
Layered email security paired with data loss prevention (DLP) at the communications layer — content inspection, threat verdicts, and quarantine logs retained as evidence.
System & Communications Protection
Image-based backup and tested recovery with documented RPO/RTO — so ransomware and hardware failure are recoverable events, not compliance failures.
Media Protection Contingency Planning
Ongoing phishing simulation and role-based training with per-user completion and click-rate records — defensible evidence the human control is working.
Awareness & Training
Migration, secure configuration, and the compliant boundary for controlled information — built in the Microsoft cloud tenancy the Defense Industrial Base relies on.
Migrations and secure configuration of your Microsoft 365 and Azure environment — including standing up CUI enclaves in GCC High where the data requires it.
Design and stand-up of a compliant boundary for CUI and ITAR technical data — a defined data and access boundary that also shrinks your assessment scope.
Right-sizing your GCC High and Microsoft licensing for both compliance and cost — the right entitlements to meet the controls without paying for capacity you do not use.
Request a readiness assessment. We will map your current stack to the NIST SP 800-171 control families, show you the gaps, and stand up the managed services that close them.
