  • CMMC Readiness Transformation for a Federal Contractor

    Preparing for CMMC compliance consulting requires more than documentation. Organizations handling Controlled Unclassified Information need to understand their environment, implement applicable controls, document how those controls operate, and prepare evidence for assessment.

    The Challenge

    The client was a federal contractor that needed to move from a non-CMMC-compliant environment toward an assessment-ready security program aligned with CMMC and NIST 800-171.

    The Approach

    We assessed the environment against applicable NIST 800-171 requirements, identified gaps, prioritized remediation, mapped controls to the technology environment, and developed supporting documentation and evidence.

    Implementation

    The engagement included control implementation, security configuration, policy and procedure development, SSP and POA&M support, and evidence preparation. The goal was to connect documentation to actual technical and operational controls.

    Assessment Preparation

    The organization progressed toward an assessment-ready position by connecting controls, documentation, ownership and evidence into a structured compliance program.

    Outcome

    The project moved the contractor from an informal security posture toward a documented, controlled and assessment-focused environment.

    Microsoft technology can also provide a foundation for identity, endpoint, collaboration and data controls. See Microsoft 365 consulting.

  • Microsoft 365 GCC High Tenant Migration

    Moving from commercial Microsoft 365 to GCC High is a major cloud transformation for organizations supporting federal contracts. The migration must address users, identity, applications, data, security and business continuity.

    The Challenge

    The client needed to transition its Microsoft 365 environment to GCC High while supporting federal contracting and compliance requirements.

    Migration Planning

    We assessed users, groups, mail, data, applications, authentication and administrative dependencies, then developed a migration approach designed to minimize disruption.

    Identity and Security

    Identity architecture was central to the project. Microsoft Entra ID, authentication, administrative access and security policies were considered as part of the new environment.

    Data and Workloads

    Migration activities addressed Microsoft 365 workloads and data while accounting for configuration differences, security requirements, validation and user communications.

    Compliance Alignment

    The cloud environment was treated as part of the broader compliance boundary rather than as an isolated IT migration. See CMMC compliance.

    Outcome

    The project established a GCC High environment aligned to the client’s federal contracting objectives and created a structured foundation for ongoing administration.

  • NIST 800-171 / CMMC Gap Assessment & Remediation

    A CMMC readiness program starts with knowing where the organization actually stands. WS Tech Consulting performed a structured gap assessment and remediation engagement focused on NIST 800-171 and CMMC requirements.

    The Challenge

    The client needed to understand which requirements were implemented, which required improvement, and what evidence would be needed to demonstrate implementation.

    Gap Assessment

    We reviewed the environment against applicable NIST 800-171 and CMMC requirements, considering technology, policies, procedures, access controls, identity, endpoint security, data protection and operations.

    Remediation Roadmap

    Findings were organized into actionable priorities based on risk, dependencies, effort and evidence requirements.

    Documentation and Evidence

    The engagement included support for System Security Plan documentation, POA&M development and evidence organization, connecting documentation to actual controls.

    Outcome

    The client gained a clearer view of its readiness position, a prioritized remediation path and a structured foundation for assessment preparation.

    See CMMC compliance consulting and Microsoft 365 consulting.

  • CMMC Level 2: Requirements, Readiness and Assessment Guide

    CMMC Level 2: Requirements, Readiness and Assessment Guide

    CMMC Level 2 is intended for organizations that need to protect Controlled Unclassified Information in applicable defense contracting environments.

    Current Program Status

    As of September 2026, official CMMC guidance states that Phase II requirements were suspended in July 2026 while Phase I self-assessment requirements remain active. Verify current obligations against contracts and official guidance.

    NIST SP 800-171 Alignment

    Under the current framework, Level 2 has been aligned to the 110 security requirements in NIST SP 800-171 Rev. 2. NIST Rev. 3 has superseded Rev. 2 as a NIST publication, but current CMMC materials continue to reference Rev. 2 pending future changes.

    Core Readiness Areas

    • System and CUI scope
    • Access control
    • Identification and authentication
    • Configuration management
    • Audit and accountability
    • Incident response
    • Media protection
    • Personnel security
    • System and communications protection
    • System and information integrity

    Documentation Matters

    See our CMMC SSP guide and POA&M guide.

    Gap Assessment

    A structured CMMC gap assessment can identify missing controls and evidence gaps.

  • CMMC System Security Plan (SSP): What Businesses Need to Know

    CMMC System Security Plan (SSP): What Businesses Need to Know

    A System Security Plan is a foundational document for organizations working with NIST SP 800-171 and CMMC.

    What an SSP Should Describe

    • System boundaries
    • Environment and architecture
    • CUI flows and locations
    • Responsible systems and services
    • Implementation of security requirements
    • Roles and responsibilities
    • Relevant policies and procedures

    Why Accuracy Matters

    An SSP should reflect the actual environment. Generic documentation that does not match real configurations creates assessment risk.

    SSP and CUI Scope

    Read our CUI guide.

    SSP and POA&M

    Outstanding work may need tracking through a POA&M where permitted.

    Microsoft Environment Documentation

    For Microsoft environments, SSP documentation may need to describe identity, endpoints, cloud services, data protection, logging and monitoring. See CMMC and Microsoft 365.

    Keep the SSP Current

    Treat the SSP as a living document and update it when architecture, services or CUI handling change.

    Our CMMC compliance consulting services can support SSP development and remediation planning.

  • CMMC POA&M: Plan of Action and Milestones Explained

    CMMC POA&M: Plan of Action and Milestones Explained

    A Plan of Action and Milestones is used to document identified cybersecurity deficiencies and actions planned to correct them.

    What a POA&M Tracks

    • Identified deficiency
    • Required remediation
    • Responsible owner
    • Dependencies
    • Target completion date
    • Status and evidence

    Not a Substitute for Implementation

    A remediation plan does not mean a requirement is implemented.

    Connect POA&M to the SSP

    The SSP describes the environment, while the POA&M tracks unresolved work where permitted.

    Prioritize Remediation

    Consider impact, security risk, dependencies, technical complexity and assessment timing.

    Use the Gap Assessment

    A CMMC gap assessment can identify work that needs remediation.

    Microsoft Remediation

    Common work can involve identity, MFA, Conditional Access, endpoint configuration, logging, data protection and permissions. Explore Microsoft 365 security consulting.

  • CMMC and Controlled Unclassified Information (CUI): What Businesses Need to Know

    CMMC and Controlled Unclassified Information (CUI): What Businesses Need to Know

    Controlled Unclassified Information is one of the most important concepts in CMMC and NIST SP 800-171 planning.

    Why CUI Affects CMMC Scope

    Systems that process, store or transmit CUI—and systems that provide security protection—can affect compliance scope.

    Map CUI Flows

    Document how CUI enters the organization, where it is stored, who accesses it, how it is shared and how it leaves or is destroyed.

    Control Access

    Access should be limited according to business need and applicable requirements.

    Protect CUI in Microsoft 365

    Evaluate licensing, configuration, data location, permissions and security requirements before placing CUI into a service.

    See CMMC and Microsoft 365 and Microsoft 365 consulting.

    CUI and the SSP

    Your System Security Plan should accurately describe relevant systems and boundaries.

    Start With Scope Before Buying Tools

    Understand the CUI environment and applicable requirements before choosing technology.

    Our CMMC compliance consulting approach starts with environment, scope, requirements and gaps.

  • What Is CMMC? A Business Guide to CMMC Compliance

    What Is CMMC? A Business Guide to CMMC Compliance

    The Cybersecurity Maturity Model Certification (CMMC) program is designed to strengthen cybersecurity across organizations that support defense contracts and handle certain federal information.

    Why CMMC Exists

    Defense contractors and subcontractors can possess sensitive federal information in nonfederal systems. CMMC establishes a framework for verifying cybersecurity practices associated with applicable contract requirements.

    CMMC Levels

    CMMC includes different levels based on the type of information and cybersecurity requirements involved. Organizations should determine which requirements apply based on their contracts, information and scope.

    Current CMMC Status in 2026

    Official CMMC guidance states that Phase II requirements were suspended on July 13, 2026, while Phase I self-assessment requirements remain in place. Monitor the official CMMC program page for updates.

    CMMC and NIST SP 800-171

    CMMC Level 2 has been tied to NIST SP 800-171 Rev. 2 under the current framework. Learn more in our CMMC and NIST SP 800-171 comparison.

    What Is CUI?

    Controlled Unclassified Information requires safeguarding or dissemination controls under applicable law, regulation or policy. See our CUI and CMMC guide.

    How Businesses Prepare

    1. Understand contract requirements.
    2. Identify systems and information in scope.
    3. Perform a gap assessment.
    4. Develop or update the SSP.
    5. Track remediation.
    6. Implement controls.
    7. Organize evidence.

    Microsoft 365 and CMMC

    Microsoft 365 can be part of a regulated environment, but configuration, licensing, identity, endpoint controls and information handling must be evaluated carefully. Read our CMMC and Microsoft 365 guide.
