Overview
Rubrik Government by Rubrik is a backup & recovery solution with FedRAMP authorization targeting CMMC Level 2 compliance. It provides 83% coverage of NIST 800-171 controls for defense contractors handling CUI.
What This Means for Defense Contractors
Rubrik 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 Rubrik Government should verify that their System Security Plan (SSP) documents how this tool fits within their authorization boundary.

Strengths
Using Rubrik Government in a CMMC Environment
For defense contractors already using Rubrik 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 Rubrik Government's security controls align with your authorization boundary. With 83% NIST 800-171 coverage, Rubrik Government provides a strong compliance foundation, though the 2 remaining control gaps will need compensating controls or supplementary tools.
CMMC-Ready Backup & Recovery Alternatives
CMMC Compliance Analysis for Rubrik Government
Rubrik Government demonstrates strong CMMC Level 2 readiness with 83% NIST 800-171 coverage, positioning it as a viable backup solution within a contractor's authorization boundary. The platform excels in Access Control (3.1.x), Audit and Accountability (3.3.x except 3.3.8), Configuration Management (3.4.x except 3.4.1), and System and Information Integrity (3.14.x) families through its DoD SRG IL4/IL5 certification and STIG-hardened configurations. Its continuous monitoring capabilities and automated compliance reporting directly support Incident Response (3.6.x) and System and Communications Protection (3.13.x) requirements. However, critical gaps in 3.3.8 (audit log protection) and 3.4.1 (baseline configurations) require immediate attention, as C3PAO assessors will scrutinize backup systems handling CUI data flows. The dedicated government data centers and FedRAMP authorization provide strong foundational security, but assessors will verify that audit logs are cryptographically protected and baseline configurations are properly documented. Unlike competitors such as Veeam or Commvault, Rubrik Government's purpose-built compliance features and government-specific deployment model reduce implementation complexity. The platform can remain within the authorization boundary due to its government cloud infrastructure, though contractors must ensure proper network segmentation and access controls. C3PAO assessors will evaluate the platform's ability to maintain CUI confidentiality during backup operations and verify that restoration processes maintain proper access controls and audit trails.
Configuration Guide
Address the 3.3.8 gap by implementing cryptographic protection for all audit logs through Rubrik's native encryption capabilities and configuring FIPS 140-2 validated cryptographic modules within the government cloud environment. For 3.4.1 compliance, establish and document baseline configurations using Rubrik's policy engine to define standard backup policies, retention schedules, and security settings. Configure automated policy enforcement to prevent deviations from approved baselines. Implement compensating controls including enhanced monitoring of configuration changes through Rubrik's API integration with SIEM solutions, and document these controls in the SSP's CA-7 continuous monitoring section. Timeline estimate: 4-6 weeks for initial remediation, including 2 weeks for cryptographic configuration, 2 weeks for baseline documentation, and 1-2 weeks for compensating control implementation. Maintain compliance through Rubrik's automated compliance reporting features, scheduling weekly configuration drift reports and monthly audit log integrity checks. Prepare evidence including baseline configuration documentation, cryptographic implementation details, audit log protection verification, policy enforcement reports, and incident response procedures specific to backup system failures. Document all configurations in the SSP's SC (System and Communications Protection) and CM (Configuration Management) control families, ensuring C3PAO assessors can verify implementation effectiveness during on-site reviews.
