Independent CMMC assessments
Structured assessment planning, evidence review, interviews, and testing against the applicable CMMC requirements, with findings documented through the prescribed process.
Discuss an assessment ↗ASSESS • IMPLEMENT • SUSTAIN
Build a defensible security program.
Keep the mission moving.
Across independent C3PAO assessments, RPO implementation support, RMF authorization, specialized assets, and secure cloud enclaves, SOS helps teams turn requirements into operating capability.

ASSESSOR PERSPECTIVE / PRACTITIONER DELIVERY
Two roles. Clear responsibilities.
SOS brings the assessment perspective of a CMMC Third-Party Assessment Organization (C3PAO) and the implementation focus of a Registered Practitioner Organization (RPO). Engagements are scoped to preserve assessment impartiality.
Readiness and remediation
Practical help defining the CUI boundary, implementing controls, preparing SSPs and POA&Ms, managing evidence, and operating the program over time.
Explore implementation delivery ↗Assessment and advisory work are evaluated for conflicts of interest before engagement. A readiness or implementation client should not assume SOS can also perform its certification assessment.
ADJACENT NIST EXPERTISE
Security controls and secure software, built into the program.
These disciplines strengthen the control environment beyond a checklist and connect architecture decisions to operational evidence.
Security & privacy controls
Control selection, tailoring, implementation, assessment preparation, and continuous monitoring for RMF and ATO programs. SOS connects the control baseline to SSP narratives, inherited responsibilities, POA&Ms, and defensible evidence.

Secure Software Development Framework practices for preparing teams, protecting code, producing well-secured software, and responding to vulnerabilities across the software lifecycle.

One partner across the full lifecycle.
Engage SOS for a focused workstream or a coordinated program—from the first CUI boundary discussion through authorization and ongoing operations.

Take the CMMC quick checkGOVERN • MONITOR • EXECUTE
Run compliance as an operating program.
Documentation, monitoring, and work tracking should reinforce one another. SOS connects requirements to evidence, findings to owners, and decisions to a visible delivery plan.
Keep the record assessment ready.
We build and maintain the system narrative behind the controls, with traceable responsibilities and a clear path from requirement to implementation and evidence.
- System security plans and boundary descriptions
- Policies, procedures, control narratives, and inheritance
- Risk registers, POA&Ms, evidence inventories, and review records
Typical outputA current, reviewable body of evidence
See changes before they become gaps.
We define the telemetry, review rhythm, escalation path, and control checks needed after implementation and through authorization or assessment cycles.
- Sentinel and Defender signal coverage and triage
- Vulnerability, configuration, and exception follow-up
- Recurring metrics, control reviews, and evidence refresh
Typical outputFindings, decisions, and trends with owners
Turn findings into finished work.
Security work is organized into phases with accountable owners, dependencies, target dates, and formal review points for implementation and sustainment.
- Remediation backlog and milestone planning
- Assigned actions, due dates, risks, and status reviews
- Quality gates linking completed tasks to evidence
Typical outputA visible plan from gap to closure
SECURITY ARCHITECTURE / INTERACTIVE
Seven controls. One coherent boundary.
Explore how identity, network, data, endpoints, detection, and cloud applications work together in a GCC High enclave. Select a numbered control to inspect its architecture.
01 / IDENTITY & ACCESS
Device trust before access
Intune manages device configuration and reports compliance signals to Microsoft Entra ID. Conditional Access uses those signals with identity, location, and sign-in risk to decide whether users may reach approved cloud resources. Policies are designed around each user and CUI workflow.

GCC High secure data flow
This example traces CUI between a protected virtual workspace, approved storage and Microsoft 365 GCC High services. Identity, policy, data protection, and monitoring provide separate control paths. We map the actual tenant, services, and inherited responsibilities before using a design as an implementation baseline.
Discuss your data flow ↗
TURNKEY ENCLAVE IMPLEMENTATION
Choose the boundary that fits the work.
Each variant combines architecture, control ownership, SSP and procedures, evidence, monitoring, and operational support. The diagrams illustrate starting patterns; final boundaries follow actual CUI flows and equipment.
Keep CUI in the cloud workspace
Users connect through Windows App with Entra ID, MFA, and Conditional Access. CUI work runs on AVD session hosts and approved GCC High services; local download, clipboard, USB, and print pathways are restricted by policy.
Implementation path
Explore Variant 1 ↗- Map CUI applications, users, and cloud services; define the authorization boundary.
- Deploy the AVD workspace, identity policies, network egress, collaboration, and protection controls.
- Validate redirection restrictions, monitoring, backup, evidence, and operating procedures.
Extend trust to approved devices
Keep the virtual enclave while adding managed endpoints for approved local work. Intune enrollment, Defender protection, device compliance, Conditional Access, encryption, and controlled peripherals become part of the assessed boundary.
Implementation path
Explore Variant 2 ↗- Identify which tasks require local CUI processing and which users and devices are authorized.
- Harden and enroll endpoints; define access, storage, transfer, printing, and recovery rules.
- Test cloud-to-device data flows and collect endpoint and policy evidence.
Control the equipment handoff
Extend the hybrid model to isolated lab, CNC, OT, or other specialized assets through an explicitly designed transfer process. The air gap and media workflow are documented, with roles and safeguards matched to the equipment's capabilities.
Implementation path
Explore Variant 3 ↗- Trace files to and from equipment and classify each asset and transfer point.
- Design approved media handling, malware checks, custody, physical controls, and exceptions.
- Validate the handoff with operators and document evidence and residual risk.

HOW WE WORK
Make the boundary clear. Make the controls real.
We connect architecture decisions with the documents, evidence, and operating routines that an assessment or authorization depends on.
01
Define
Map data, users, systems, dependencies, requirements, and ownership.
02
Design
Select the boundary, inherited controls, technical safeguards, and procedures.
03
Prove
Implement controls and assemble testable evidence and authorization artifacts.
04
Sustain
Track changes, findings, vulnerabilities, monitoring, and recurring reviews.
FIND YOUR PATH
What are you working toward?
Choose the outcome closest to your current need. This is a starting point for a conversation, not an assessment or compliance determination.
RECOMMENDED START
CMMC scope and readiness review
Start with your contracts, CUI flows, asset categories, and existing controls. Then prioritize gaps and evidence before selecting implementation work.
- Boundary and CUI flow review
- Control and evidence baseline
- Remediation roadmap
