Overview
Cisco Webex for Government by Cisco is a collaboration solution with FedRAMP authorization targeting CMMC Level 2 compliance. It provides 87% coverage of NIST 800-171 controls for defense contractors handling CUI.
What This Means for Defense Contractors
Cisco Webex for 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 Cisco Webex for Government should verify that their System Security Plan (SSP) documents how this tool fits within their authorization boundary.

Strengths
Using Cisco Webex for Government in a CMMC Environment
For defense contractors already using Cisco Webex for 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 Cisco Webex for Government's security controls align with your authorization boundary. With 87% NIST 800-171 coverage, Cisco Webex for Government provides a strong compliance foundation, though the 2 remaining control gaps will need compensating controls or supplementary tools.
CMMC-Ready Collaboration Alternatives
CMMC Compliance Analysis for Cisco Webex for Government
Cisco Webex for Government demonstrates strong CMMC Level 2 readiness with 87% NIST 800-171 coverage, making it suitable for defense contractors handling CUI in collaborative workflows. The platform excels in Access Control (3.1), System and Communications Protection (3.13), and Identification and Authentication (3.5) families through dedicated FedRAMP Moderate government data centers, robust role-based access controls, and MFA enforcement. However, gaps in controls 3.5.3 (multifactor authentication for local access) and 3.5.7 (privileged account management) present remediation challenges. During C3PAO assessment, evaluators will scrutinize the government cloud boundary separation, data residency controls, and privileged user management processes. The tool can exist within the CMMC authorization boundary as it maintains proper CUI handling through encryption at rest/transit and comprehensive audit logging. Compared to Microsoft Teams GCC High or Google Workspace for Government, Webex Government offers competitive compliance positioning but requires additional compensating controls for privileged access management. The FedRAMP Moderate authorization provides a solid foundation, though contractors must implement additional CMMC-specific controls. C3PAO assessors will validate that CUI workflows remain within the government cloud instance and that proper data classification handling procedures are documented. The platform's SIEM integration capabilities support continuous monitoring requirements essential for maintaining CMMC compliance posture.
Configuration Guide
Configure Webex for Government with maximum security settings including enforced MFA for all users, role-based access with least privilege principles, and integration with enterprise identity providers supporting PIV/CAC authentication. Document compensating controls for gaps 3.5.3 and 3.5.7 in the System Security Plan, specifically detailing how organizational policies and technical controls address multifactor authentication requirements and privileged account oversight. Implement continuous monitoring through SIEM integration, enabling real-time audit log collection and automated compliance reporting. Timeline: Initial configuration requires 4-6 weeks including user provisioning, security policy implementation, and documentation updates. Ongoing maintenance involves quarterly access reviews, monthly security configuration validation, and continuous audit log monitoring. Prepare evidence including configuration screenshots, access control matrices, audit log samples, and privileged user management procedures for C3PAO review. Establish change management procedures ensuring all Webex modifications undergo security impact assessment. Implement data loss prevention controls and user training programs addressing CUI handling within collaborative environments. Maintain separation between commercial Webex instances and government cloud deployment. Document incident response procedures specific to collaboration platform security events and establish backup communication channels for continuity planning.
