Privileged Access Management

PAM — AC & IA Control Families

Keeper Security PAM

Enterprise password manager and PAM platform with GovCloud offering. Zero-knowledge architecture. Supports FIPS 140-2 encryption, role-based access, audit logging, and SSO/SAML. Deployed in GCC High environments. Native Sentinel log integration for SIEM visibility.

Relevant: AC.1.001 · AC.2.006 · IA.1.076 · IA.3.083 · AU.2.041
Evaluated in production GovCon environment. Solid for CMMC L2. KeeperPAM adds secrets management and privileged session management for L3 posture.
Microsoft Entra ID (GCC High) Identity

Identity and access management foundation for GCC High tenants. Entra ID P2 (included in G5) adds PIM (Privileged Identity Management), Identity Protection, and Conditional Access with risk-based policies. Required baseline for most CMMC AC and IA controls.

Relevant: AC.1.001 · AC.2.005 · AC.2.006 · IA.1.076 · IA.1.077 · IA.2.078
Non-negotiable baseline for GCC High tenants. Entra ID P1 (included in Business Premium and G3) covers most L2 requirements; P2 (G5) adds PIM which is important for audit evidence.
CyberArk PAM

Enterprise-grade PAM with FedRAMP authorization. Privileged session management, secrets vault, endpoint privilege management. Significant implementation complexity and cost — better fit for 500+ seat organizations with dedicated security teams.

Relevant: AC.2.006 · AC.2.007 · IA.3.083 · AU.2.041 · AU.2.042
~Industry standard at enterprise scale. Overkill for most small-to-mid DIB contractors. Evaluate Keeper first; escalate to CyberArk only if compliance scope demands it.
Endpoint Security

EDR — SI & IR Control Families

Microsoft Defender for Endpoint EDR

Included in G5 (Defender P2) or available as add-on for G3. Native GCC High support, feeds directly into Sentinel. Covers vulnerability management, EDR, automated investigation, and threat intelligence. Strongest audit trail for CMMC SI controls.

Relevant: SI.1.210 · SI.1.211 · SI.2.214 · IR.2.092 · IR.2.093 · AU.2.041
First choice for GCC High tenants already in the Microsoft stack. The native Sentinel integration produces the correlated audit log evidence CMMC assessors want to see.
CrowdStrike Falcon (Government) EDR

FedRAMP High authorized EDR platform. Falcon GovCloud covers Prevent (NGAV), Insight (EDR), Discover (asset visibility), and Spotlight (vulnerability management). Strong for organizations not fully committed to the Microsoft security stack.

Relevant: SI.1.210 · SI.1.211 · SI.2.214 · IR.2.092 · RA.2.141
Best-in-class EDR. Stronger standalone EDR than Defender for non-Microsoft environments. If your SIEM is Splunk instead of Sentinel, CrowdStrike is the natural pairing.
Tenable Nessus / Tenable.io Vulnerability Mgmt

Industry-standard vulnerability scanner. Tenable.io GovCloud is FedRAMP Moderate authorized. Covers RA.2.141 (vulnerability scanning) and provides the remediation evidence trail CMMC assessors look for in CA and RA domains.

Relevant: RA.2.141 · RA.2.142 · CA.2.157 · SI.2.214
Nessus Essentials is free for up to 16 IPs — useful for initial scoping. Tenable.io adds continuous monitoring and remediation tracking for assessment evidence packages.
Compliance Automation & GRC

GRC — CA & Documentation

Vanta GRC

Compliance automation platform with CMMC support. Continuous control monitoring, evidence collection, SSP/policy templates, and integrations with M365, AWS, GCP, and security tools. Strongest fit for organizations with existing commercial stack transitioning to CMMC.

Relevant: CA.2.157 · CA.2.158 · CA.2.159 · AU.2.041 · AU.2.042
~Good for documentation and evidence organization. Does not replace a practitioner assessment — it organizes the evidence a practitioner and C3PAO will evaluate. Best used from day one of a CMMC program.
Drata GRC

Automated compliance platform covering CMMC, SOC 2, ISO 27001, and others simultaneously. Strong integration ecosystem. Useful for organizations managing multiple compliance frameworks — the shared evidence model reduces duplication burden.

Relevant: CA, AU, AC domains — evidence collection and tracking
~Strongest when you need multiple frameworks in parallel. If CMMC is your only framework, Vanta may be sufficient. If you also have SOC 2 customers or ISO 27001 aspirations, Drata earns its cost.
Microsoft Purview Compliance Manager GRC

Included in G3/G5. Built-in CMMC assessment template maps your M365 tenant configuration directly to NIST 800-171 controls. Produces compliance score, identifies gaps, and generates evidence for controls that M365 handles automatically.

Relevant: All 14 NIST 800-171 control families for M365-covered controls
Use this first — it's already included in your license and covers all M365-resident controls automatically. Gaps it surfaces are the non-M365 controls that need a separate tool or process.
Secure Communications

CUI-Safe Collaboration

PreVeil Secure Email

End-to-end encrypted email and file sharing layered on top of Outlook and Gmail. Zero-knowledge — even PreVeil can't read your data. Purpose-built for CUI handling. CMMC-aligned and complements (not replaces) GCC High for organizations handling highly sensitive communications with cleared partners.

Relevant: SC.3.177 · SC.1.175 · MP.2.120 · AC.1.001
~Strong choice for CUI email outside GCC High environments or for ITAR-sensitive communications with cleared primes. Evaluate if you have partners not yet on GCC High who need to share CUI with you.
Microsoft Teams (GCC High) Collaboration

Included in all GCC High licenses. ITAR-compliant collaboration for CUI — but only in the GCC High tenant, not commercial Teams. Federation with external partners requires configuration. See the GCC High licensing guide for Teams-specific limitations.

Relevant: SC.1.175 · AC.1.001 · SC.3.177
Primary collaboration platform for GCC High tenants. No additional cost. Key compliance caveat: ensure all CUI collaboration occurs in GCC High Teams — not commercial Teams, even for the same org.
ConnectWise ScreenConnect Remote Access

Remote support and access platform widely used by MSPs and IT teams supporting defense contractors. On-premises hosting option keeps data in your environment. Relevant for CMMC MA (Maintenance) and PE controls around remote access to covered systems.

Relevant: MA.2.112 · MA.2.113 · AC.2.006 · PE.1.131
~Viable option for remote maintenance access documentation. On-prem deployment preferred for CUI environments. Ensure all remote sessions to CUI systems are logged and session-recorded as part of your MA evidence package.
Development & Source Control

Code & Configuration Management

GitHub Enterprise (GHES / EMU) Source Control

GitHub Enterprise Server (self-hosted) or Enterprise Managed Users (EMU) on github.com provides enterprise-grade source control with SAML SSO, audit logs, secret scanning, and branch protection. For CUI-adjacent code, GHES on-prem or EMU tied to GCC High Entra ID is the defensible posture. GitHub.com commercial is not appropriate for source code that is itself CUI.

Relevant: CM.2.061 · CM.2.062 · AC.2.006 · AU.2.041 · SA.2.066
The right choice for DIB software development organizations. GHES gives you full control and auditability. EMU with Entra ID SSO is the cloud path for GCC High-aligned identity. Evaluate FedRAMP authorization status before selecting deployment model.
Azure DevOps (GCC High) DevOps

Microsoft's DevOps platform covering source control, CI/CD pipelines, boards, and artifact management. Important caveat: Azure DevOps is NOT natively available in GCC High. Organizations needing DevOps in a GCC High environment must use GitHub Enterprise or evaluate Azure DevOps on Azure Government separately.

Relevant: CM.2.061 · CM.2.062 · SA.2.066
Not available in GCC High tenant natively — this surprises many teams. Plan your CI/CD pipeline architecture before committing to Azure DevOps if your CMMC boundary is GCC High. GitHub Enterprise is the current recommended alternative.
Splunk Enterprise Security SIEM

SIEM and SOAR platform with FedRAMP High authorization. Market-leading log correlation, threat hunting, and compliance reporting. Significantly higher complexity and cost than Microsoft Sentinel — justified for organizations with diverse multi-vendor environments or high-volume telemetry requirements.

Relevant: AU.2.041 · AU.2.042 · AU.2.043 · AU.3.045 · IR.2.092
~Best in class for SIEM. However, if you're already on G5 with Sentinel included, Splunk is hard to justify for most small-to-mid DIB contractors. Evaluate total cost of ownership before displacing Sentinel.

A Note on Tool Selection

No tool makes you CMMC compliant. Tools provide technical controls — you still need SSP documentation, policy procedures, training records, and process evidence. The most common mistake in CMMC programs is buying tools before scoping the boundary. Scope first. Buy tools second. Document both. If you're not sure where to start, schedule a call — the first conversation is always free.
