Is Google Drive Okay for CUI? A Clear Explanation

If you're running a small to mid-sized manufacturing company, chances are you've used or considered using cloud storage options like Google Drive to keep your documents and files organized. But when it comes to handling Controlled Unclassified Information (CUI), many business owners ask: Is Google Drive okay for CUI?.

What is CUI and Why Does it Matter?

Controlled Unclassified Information (CUI) is a category of sensitive government information that is not classified but still requires safeguarding according to federal guidelines. It covers a broad range of data, including manufacturing designs, proprietary processes, supplier info, and other sensitive business info.

Handling CUI properly is crucial because mishandling can result in legal penalties, loss of contracts, or damage to your company’s reputation. Therefore, understanding what storage solutions are compliant with CUI requirements is essential.

Google Drive and Its Security Measures

Google Drive is a popular cloud storage solution, offering convenience, collaboration features, and integration with Google's suite of tools. It uses encryption for data at rest and in transit, and provides controls like two-factor authentication (2FA). These are strong security features for everyday use.

However, security does not just mean encryption. It also involves compliance with specific regulations, proper access controls, audit capabilities, and data management policies—especially when handling sensitive information like CUI.

Is Google Drive Approved for CUI?

Officially, Google Drive is NOT considered an approved platform for storing CUI on its free or standard plans, primarily because it does not meet the strict security and compliance standards outlined in federal regulations such as the Federal Acquisition Regulation (FAR) and DFARS.

Specifically, under the Defense Federal Acquisition Regulation Supplement (DFARS) 252.204-7012 and NIST SP 800-171 standards, certain steps must be taken to ensure a platform can properly handle CUI—including controlled access, audit logs, and secure storage protocols. Google Drive, in its default form, does not satisfy these requirements.

What Are the Risks of Using Google Drive for CUI?

• Limited control over user access—standard Google Drive sharing settings may allow unintended access.

• Insufficient audit and reporting features for tracking who viewed or edited files.

• Potential for data breaches if user credentials are compromised, especially considering Google’s global infrastructure.

• Non-compliance with government regulations, risking losing contracts or legal penalties.

Can Google Drive Be Made CUI-Ready?

While Google Drive in its usual form isn’t compliant, some organizations create a compliant environment by customizing their approach:

1. Use Google Workspace Business Plus or Enterprise plans, which offer advanced security features.

2. Implement strict access controls, multi-factor authentication, and regularly review sharing permissions.

3. Leverage Google’s Confidential Mode for email sharing of sensitive info, though this doesn’t replace proper CUI handling.

4. Develop internal policies that limit file sharing and implement employee training.

5. Supplement with third-party tools, such as DLP (Data Loss Prevention) solutions, that monitor and control data leakage.

Better Alternatives for Handling CUI

For manufacturing companies needing to handle CUI, it’s generally safer to consider dedicated solutions designed for government compliance:

• Cloud Service Providers Qualified for CUI: Platforms like Microsoft Azure Government and AWS GovCloud (U.S.) are certified for CUI storage and handling.

• On-Premises Storage: Keeping data within your own secure infrastructure, with proper security controls, might be appropriate for some companies.

• Specialized CUI-compliant Platforms: Companies like MissionReady

Summary: Use Google Drive with Caution

In short, Google Drive is not officially approved for storing CUI. While it offers solid encryption and security features for everyday work, it does not meet the strict compliance requirements mandated by federal standards for CUI handling.

If your company is just starting to handle sensitive government data, consult with your legal or compliance advisor. For ongoing CUI management, consider platforms specifically designed and certified for this purpose.

Final Thought

Protecting your company's sensitive information isn’t just about convenience—it’s about doing it right. Cloud solutions are powerful tools, but choosing the right one depends on your specific security needs and compliance obligations. When in doubt, prioritize platforms that are officially certified for CUI handling, and always implement proper access controls and employee training to keep your information safe.
