Partial CUI Compliance
1 NIST 800-171 gaps detected. FedRAMP Moderate only. Many contractors use commercial Okta assuming IAM compliance is covered, but the commercial version is insufficient for DoD CUI requiring FedRAMP High.

Overview
Commercial Okta holds FedRAMP Moderate authorization. While it provides strong IAM capabilities, it is not authorized at the High impact level required for DoD CUI. Contractors with DoD contracts should use Okta for Government (High) or Microsoft Entra ID in GCC High.
CUI Risk Assessment
FedRAMP Moderate only. Many contractors use commercial Okta assuming IAM compliance is covered, but the commercial version is insufficient for DoD CUI requiring FedRAMP High.
Using Okta (Commercial) in a Defense Contractor Environment
Okta (Commercial) presents a significant compliance risk for defense contractors handling CUI in DoD environments. While it provides robust identity and access management capabilities, its FedRAMP Moderate authorization is insufficient for DoD CUI requiring FedRAMP High. Defense contractors typically use Okta to control access to engineering systems containing technical drawings (ITAR-controlled designs), financial systems with contract pricing data, and HR systems with employee PII including security clearance information. Within a CMMC Level 2 authorization boundary, Okta (Commercial) creates a compliance gap because it processes authentication data and potentially stores user attributes that constitute CUI metadata. DCMA assessors consistently flag commercial Okta deployments during CMMC assessments, specifically noting the FedRAMP authorization level mismatch and potential for CUI spillover into non-authorized cloud infrastructure. Compensating controls such as data classification labeling, enhanced logging, and strict boundary definitions cannot overcome the fundamental FedRAMP authorization gap. Recent DIBCAC reviews have specifically called out contractors using commercial SaaS IAM solutions without proper FedRAMP High authorization, leading to findings under NIST 800-171 control 3.13.8 (transmission control). The Defense Industrial Base has seen increased scrutiny of IAM solutions following supply chain compromise incidents, making proper authorization levels critical for maintaining DoD contract eligibility.
Deployment & Architecture
Deployment Model: Cloud SaaS (vendor-hosted)
Okta (Commercial) operates within a FedRAMP-authorized boundary. CUI can be processed within the authorization scope, but contractors must verify their specific use case falls within the system's security boundary as documented in the SSP.
Migration Guidance
Defense contractors must migrate from Okta (Commercial) to an authorized alternative within 12-18 months to maintain DoD contract compliance. Phase 1 (Weeks 1-4): Conduct user inventory and identify all integrated applications, document current SSO configurations, and develop migration timeline. Simultaneously begin procurement process for Okta for Government (FedRAMP High) or Microsoft Entra ID in GCC High environment. Phase 2 (Weeks 5-12): Stand up replacement IAM solution, configure initial user groups and policies, begin application integration testing in parallel environments. Export user data using Okta's APIs while ensuring CUI handling procedures during data transfer. Phase 3 (Weeks 13-20): Conduct phased user migration starting with non-CUI systems, provide mandatory user training on new authentication flows, update SSP Section 10 (system interconnections) and authorization boundary diagrams to reflect new IAM solution. Phase 4 (Weeks 21-24): Complete migration, decommission Okta Commercial tenant, update POA&M to close findings related to 3.13.8 violations. Recommended alternatives include Okta for Government ($8-15 per user/month) or Microsoft Entra ID P2 in GCC High ($9-12 per user/month). Total migration cost estimate: $50,000-150,000 for 500-user environment including professional services, training, and temporary dual-licensing.
Migration Checklist
- 1ISSO must document Okta (Commercial) as a POA&M finding under NIST 800-171 control 3.13.8 with planned remediation timeline not exceeding 180 days per DFARS 252.204-7012 requirements.
- 2Contracts officer must review active DoD contracts to determine CUI handling requirements and assess risk of using non-FedRAMP High IAM solution for contract performance.
- 3System administrator must inventory all applications integrated with Okta (Commercial) and classify which systems process, store, or transmit CUI requiring FedRAMP High authorization.
- 4ISSO must update SSP Section 2.3 (authorization boundary) to clearly identify Okta (Commercial) as external to the CUI processing environment until migration is complete.
- 5Procurement officer must initiate acquisition process for Okta for Government or Microsoft Entra ID GCC High subscription with FedRAMP High authorization.
- 6System administrator must configure enhanced logging for all Okta (Commercial) authentication events to meet AU-2 audit requirements during transition period.
- 7ISSO must implement compensating controls including network segmentation to prevent CUI data transmission through Okta (Commercial) authentication flows.
- 8Training coordinator must develop user awareness materials explaining the compliance risk and upcoming migration timeline to maintain DoD contract eligibility.
- 9System administrator must establish secure data export procedures from Okta (Commercial) ensuring CUI handling protocols are maintained during migration activities.
- 10ISSO must update continuous monitoring procedures to include monthly review of Okta (Commercial) usage until complete migration to authorized solution is achieved.
Compliance Cross-References
Okta (Commercial)'s non-compliance primarily impacts NIST 800-171 control family AC (Access Control) through inadequate authorization boundaries, and SC (System and Communications Protection) through unauthorized external service usage. The primary violation occurs under control 3.13.8 which requires cryptographic mechanisms for external connections, but the broader implication affects 3.5.1 (identification and authentication for non-organizational users) since Okta processes authentication data that may include CUI user attributes. This triggers DFARS 252.204-7012 (Safeguarding Covered Defense Information) requiring adequate security measures, and DFARS 252.204-7021 (CMMC Requirement) for Level 2 certification. Within CMMC assessment domains, this creates findings in Access Control (AC.L2) and System and Information Integrity (SI.L2) due to inadequate boundary protection. The FedRAMP authorization gap also implicates IA (Identification and Authentication) controls since the authentication service lacks proper government authorization. Defense contractors using Okta (Commercial) face automatic CMMC assessment findings and potential contract action under FAR 52.204-21 if CUI exposure is identified during government reviews.
