Achieve CMMC Compliance with Confidence
Protect sensitive assets, reduce risk, and align to DoD requirements with Sophos.
Sophos helps defense contractors and suppliers strengthen cybersecurity and support Cybersecurity Maturity Model Certification (CMMC) initiatives with proven protection, expert-led detection and response, and clear guidance for secure deployment.
Built for CMMC Environments
Sophos endpoint and XDR components can be deployed in CMMC Level 2 environments without expanding the CUI boundary—when configured according to recommended best practices.
This allows organizations to strengthen detection and response capabilities while maintaining a clear and defensible CMMC scope.
What is CMMC?
The Cybersecurity Maturity Model Certification (CMMC) is the U.S. Department of Defense’s framework for protecting sensitive information across the Defense Industrial Base (DIB). It builds on NIST SP 800-171 federal guidelines and introduces additional practices to address evolving cyber threats.
CMMC introduces scaled assessment requirements based on the sensitivity of the data, utilizing annual self-assessments for foundational levels and requiring independent third-party or government certification assessments for higher tiers.
If your organization handles Federal Contract Information (FCI) or Controlled Unclassified Information (CUI), achieving the appropriate CMMC level is essential to maintaining DoD contracts, and reducing risk in an increasingly complex threat landscape.
CMMC Levels Overview
| Level | Description | Ideal For |
|---|---|---|
| Level 1 — Foundational | Basic safeguarding of FCI using 17 practices | Small contractors |
| Level 2 — Advanced | Protection of CUI aligned with NIST SP 800-171 | Most contractors and subcontractors |
| Level 3 — Expert | Advanced protections against persistent threats | High-security environments |
Tip: Most organizations pursuing DoD contracts will need CMMC Level 2.
Clarity for CMMC Validated by a C3PAO
To help organizations confidently deploy Sophos in CMMC Level 2 environments, Sophos partnered with Coalfire, an authorized C3PAO, to co-develop a Product Applicability Guide and Customer Responsibility Matrix. This collaboration combines Coalfire’s assessor level perspective with deep technical input from Sophos product architects to clearly document how specific Sophos endpoint, XDR, MDR, and platform components function as Security Protection Assets when configured according to recommended practices. The result is clear, defensible guidance that explains what Sophos protects, how telemetry and data flows are handled, and which configurations and organizational responsibilities are required to maintain proper CMMC scope—helping customers reduce risk, avoid unnecessary CUI boundary expansion, and approach CMMC Level 2 assessments with greater clarity and confidence.
Why Sophos for CMMC
Sophos products and services are categorized as Security Protection Assets by the CMMC framework and provide security functions and capabilities to a customer’s CMMC assessment scope. Specifically, Sophos helps our customers remain secure and meet CMMC control requirements.
Protect sensitive environments without unnecessary exposure
Sophos solutions are designed to secure endpoints and infrastructure while helping avoid unnecessary expansion of the CUI boundary when configured according to best practices.
Focus on security signals—not sensitive content
Sophos analyzes structured telemetry such as events, hashes, and detections—not document contents or business data—supporting a defensible approach to CUI handling.
Gain 24/7 threat detection and response
With Sophos MDR and XDR, you get continuous monitoring, expert-led investigations, and rapid response to help reduce risk in CMMC-scoped environments
Deploy with control and confidence
Flexible configuration options allow you to align Sophos capabilities with your compliance strategy, risk tolerance, and operational requirements

CMMC FAQs
Organizations within the Defense Industrial Base (DIB) that handle Federal Contract Information (FCI) or Controlled Unclassified Information (CUI) may be required to comply with CMMC.
This applies not only to prime contractors, but also to subcontractors and suppliers supporting Department of Defense (DoD) programs. Required certification levels vary based on the type of data you handle and the specific terms of your contract.
CMMC 2.0 defines three certification levels, based on the sensitivity of the information in scope. For most organizations working directly or indirectly with the DoD, Level 2 is the most common requirement.
Level 1 (Foundational): Basic safeguards for FCI
Level 2 (Advanced): Protection of CUI, aligned with NIST SP 800‑171
Level 3 (Expert): Enhanced protections against advanced, persistent threats
Understanding your required level early helps you plan resources, timelines, and budget more effectively. This depends on your required certification level and contract language:
Level 1: Annual self‑assessment
Level 2: Self‑assessment or third‑party assessment by a C3PAO, depending on the contract
Level 3: Government‑led assessment
Successful CMMC preparation starts with clarity around your environment and scope. A structured approach helps avoid delays and typically includes:
- Confirming whether you handle FCI or CUI
- Defining system boundaries and CMMC scope
- Conducting a gap assessment against required controls
- Documenting your environment (SSP and POA&M)
- Implementing technical and administrative security controls
- Completing a readiness or mock assessment before certification
CMMC certification is based on how security controls are implemented, managed, and validated, not on any single product or vendor.
Sophos provides the tools, telemetry, and expertise to support your compliance strategy, but certification ultimately depends on your organization’s processes, configurations, and governance.
- No. CMMC certification applies to organizations that handle CUI or FCI. Sophos solutions operate as Security Protection Assets and process only Security Protection Data, not CUI or FCI. Therefore, Sophos does not require a CMMC certification or a FedRAMP moderate authorization for customers having CMMC level 2 requirements themselves to use our products and services in a compliant manner.
With Sophos organizations strengthen their security posture and support CMMC‑aligned security practices while maintaining ongoing audit readiness. Together, these capabilities support a more efficient and defensible path to compliance.
Through AI‑driven protection and 24/7 expert‑led services, Sophos enables organizations to:
- Threat Detection & Response: Detect and respond to threats faster with MDR and XDR, helping reduce risk to CUI and FCI.
- Attack Prevention: Protect endpoints, servers, and networks from advanced attacks that could disrupt compliance.
- Centralized Visibility: Maintain unified monitoring and reporting across the environment to support audit readiness and evidence collection.
- Scope Control: Better define, enforce, and reduce CMMC scope through consistent security controls and policy enforcement.
- Continuous Compliance: Support ongoing control effectiveness with continuous monitoring, making it easier to respond to auditor requests and maintain compliance over time, not just at assessment time.
