Overview
Trellix Government by Trellix is an endpoint security solution with FedRAMP authorization targeting CMMC Level 2 compliance. It provides 86% coverage of NIST 800-171 controls for defense contractors handling CUI.
What This Means for Defense Contractors
Trellix Government meets the architectural requirements for CMMC Level 2. However, CMMC compliance depends on your entire system boundary — not just individual tools. There are 2 NIST 800-171 control gaps that need remediation before assessment. Defense contractors using Trellix Government should verify that their System Security Plan (SSP) documents how this tool fits within their authorization boundary.

Strengths
Using Trellix Government in a CMMC Environment
For defense contractors already using Trellix Government, the path to CMMC compliance involves documenting the tool in your System Security Plan (SSP), ensuring proper access controls are configured, and validating that Trellix Government's security controls align with your authorization boundary. With 86% NIST 800-171 coverage, Trellix Government provides a strong compliance foundation, though the 2 remaining control gaps will need compensating controls or supplementary tools.
CMMC-Ready Endpoint Security Alternatives
CMMC Compliance Analysis for Trellix Government
Trellix Government demonstrates strong CMMC Level 2 readiness with 86% NIST 800-171 coverage, particularly excelling in Access Control (AC), System and Communications Protection (SC), and Identification and Authentication (IA) families through its STIG-hardened configurations and MFA support. The solution effectively handles CUI through real-time endpoint monitoring, data loss prevention, and encrypted communications within dedicated government data centers. However, critical gaps exist in Audit and Accountability (3.3.1) for comprehensive audit record review capabilities and Media Protection (3.3.8) for sanitization of shared system resources. During a C3PAO Level 2 assessment, evaluators will scrutinize Trellix Government's ability to maintain continuous monitoring of CUI access events and validate its sanitization procedures for memory and storage components. The FedRAMP authorization strengthens its position within CMMC authorization boundaries, as it demonstrates independent security validation. Unlike competitors such as CrowdStrike GovCloud or Microsoft Defender for Government, Trellix Government's dedicated government infrastructure and STIG compliance provide superior baseline security posturing. However, its audit logging limitations compared to solutions like Tanium or Carbon Black may require additional SIEM integration. C3PAO assessors will expect documented evidence of how Trellix Government's endpoint telemetry feeds into the organization's overall audit strategy and how compensating controls address media sanitization requirements for endpoints processing CUI.
Configuration Guide
Immediate remediation requires configuring Trellix Government's advanced logging to capture all CUI access events and implementing automated log analysis to address 3.3.1 gaps. Deploy Trellix's Data Loss Prevention module with custom CUI classification rules and establish integration with a compliant SIEM solution like Splunk Government Cloud for comprehensive audit record review. For 3.3.8 compliance, implement Trellix's secure disk wiping capabilities and document procedures for memory sanitization during endpoint decommissioning. Configure role-based dashboards for security analysts and establish automated alerting for CUI-related security events. Timeline estimate: 6-8 weeks for initial configuration, 2-4 weeks for SIEM integration, and 4-6 weeks for policy documentation and testing. Compensating controls must include manual quarterly audit reviews, documented media sanitization procedures, and integration with asset management systems. Continuous monitoring requires weekly configuration baseline reviews, monthly policy compliance checks, and quarterly penetration testing of endpoints. Evidence preparation for C3PAO review should include configuration baselines, audit log samples demonstrating CUI monitoring, sanitization procedure documentation, and proof of SIEM integration showing complete audit trail capabilities from endpoint to centralized logging infrastructure.
