CUI Risk Assessment
Not FedRAMP authorized. Using this tool for CUI creates compliance violations under NIST 800-171 and DFARS 252.204-7012.
Deployment & Architecture
Deployment Model: Self-hosted (open-source)
ONLYOFFICE has no FedRAMP authorization on record. DFARS 252.204-7012(b)(2)(ii)(D) requires an external cloud service provider to meet security requirements equivalent to the FedRAMP Moderate baseline — an authorization is the straightforward way to show that, but it is not the only one. Without one, the burden is on you to establish, document, and defend equivalency, and to meet the clause's incident-reporting and media-preservation obligations. Most contractors find an authorized alternative cheaper than carrying that burden.
Migration Checklist
- 1ISSO must immediately assess current ONLYOFFICE usage and document all CUI data locations within 48 hours per DFARS 252.204-7012 incident reporting requirements.
- 2Contracts officer must notify DCMA of potential CUI exposure and file initial incident report referencing specific contract clauses affected.
- 3Sysadmin must block all network access to ONLYOFFICE cloud services through firewall rules and proxy configurations within 24 hours.
- 4Legal team must review all contracts using ONLYOFFICE cloud services and identify potential DFARS 252.204-7021 disclosure violations requiring contractor notification.
- 5ISSO must update the System Security Plan to remove ONLYOFFICE cloud services from the authorization boundary diagram and technology inventory.
- 6Sysadmin must export all CUI documents from ONLYOFFICE cloud using encrypted channels and verify data integrity through hash validation.
- 7ISSO must create POA&M entries for NIST 800-171 controls 3.1.1, 3.1.2, 3.13.1, and 3.13.8 with migration milestones and completion dates.
- 8Contracts officer must procure FedRAMP authorized office suite alternative and validate vendor compliance documentation before deployment.
- 9Sysadmin must configure new office suite with appropriate security settings including encryption at rest, multi-factor authentication, and audit logging per NIST 800-171 requirements.
- 10ISSO must conduct final compliance validation and update authorization boundary documentation before removing POA&M entries and notifying DCMA of remediation completion.
