Even a small leak of sensitive government information can lead to major security risks and costly consequences.
Protecting sensitive government information, especially Controlled Unclassified Information (CUI), is a top priority for Department of Defense (DoD) contractors and federal agencies. With rising cybersecurity threats and strict regulations, having the right tools and strategies in place is more important than ever to prevent data leaks or accidental spills.
This blog takes a closer look at how Microsoft Purview, CMMC 2.0, and Microsoft 365 GCC High work together to build a strong defense against CUI spillage. By combining smart data protection, clear compliance rules, and a secure cloud environment, these solutions make it easier for organizations to keep critical information safe while meeting government standards.

Understanding Controlled Unclassified Information (CUI)
What is CUI?
Controlled Unclassified Information (CUI) is government data that isn’t classified but still needs to be protected and shared carefully. It should only be accessed by people who are authorized and have a valid government-related reason to see it.
The DoD CUI Program, created under Executive Order 13556, sets consistent rules for handling sensitive information like personal data, legal communications, or technical details. You’ll usually see CUI clearly labeled so everyone knows it requires special care.
Even though it’s not classified, CUI can still cause problems if it gets into the wrong hands. On its own—or combined with other information—it could expose defense-related details or break compliance laws.
What does CUI Spillage mean and what is its penalties?
A spillage happens when classified information or CUI is transferred to an information system that lacks the proper security clearance or necessary protection for CUI.
CUI spillage is specifically addressed in the CMMC requirements under section 3.1.3 / AC.L2-3.1.3 – Control CUI Flow. Failing to manage it properly can lead to serious consequences. If an organization becomes aware of a spillage and fails to report it, the resulting penalties can be severe. Therefore, it is crucial for organizations to implement and enforce strict controls over the flow of CUI data.
Although organizations can theoretically establish and enforce these data flow controls, many may not have the necessary resources to set up, maintain, and continuously verify their effectiveness.
Effectively managing and monitoring data flow controls is where Microsoft Purview Information Protection (MPIP) becomes an invaluable, often underestimated tool that can help prevent significant problems and reduce compliance risks.
Microsoft Purview Information Protection (MPIP): The Frontline Defense
Microsoft Purview is an all-in-one platform that helps organizations discover, manage, and protect their data—no matter where it lives. Whether the data is stored on company servers, in the cloud, or inside the apps teams use every day, Purview keeps it in check.
A key part of this is Microsoft Purview Information Protection (MPIP). It’s designed to automatically spot sensitive information—like Controlled Unclassified Information (CUI)—right inside Microsoft 365 apps. Using smart tools like machine learning and trainable classifiers, MPIP can detect sensitive content in emails, documents, Teams chats, SharePoint sites, and even Microsoft 365 Groups. Once it finds something sensitive, it applies sensitivity labels that stick with the data, even if it’s shared outside Microsoft’s ecosystem.
MPIP also works hand-in-hand with Microsoft Purview Data Loss Prevention (DLP). Together, they help prevent accidental leaks or unauthorized sharing by using adaptive policies that adjust based on user behavior. It keeps your data secure without disrupting how people work.
For Department of Defense (DoD) contractors handling regulated information, MPIP offers practical benefits like:
• Easy management from one place
• Clear visibility into data use from start to finish
• Ensured compliance by applying encryption, access limits, and monitoring usage according to strict rules
Important features include:
• Centralized policy control
• Automatic, real-time classification of sensitive data
• Protection applied across devices and cloud services
These capabilities make MPIP a vital tool for protecting sensitive Controlled Unclassified Information (CUI) in complex environments that combine on-premises and cloud systems.
CMMC 2.0 Readiness: Aligning Security Practices with Compliance
CMMC 2.0, or the Cybersecurity Maturity Model Certification, is the Department of Defense’s way of making sure contractors have the right cybersecurity measures in place—especially when it comes to protecting Controlled Unclassified Information (CUI). The updated version is simpler and more focused, breaking things down into just three levels. If you’re aiming for Level 2, you’ll need to implement all 110 security controls from NIST SP 800-171, which are essential for defending CUI against cyber threats.
Getting ready for CMMC 2.0 involves a few key steps, like:
• Doing self-assessments or working with a third-party auditor
• Setting up strong access controls
• Using multi-factor authentication, encryption, and continuous monitoring
• Having a solid incident response plan in place
Tools from Microsoft, like Microsoft Purview Information Protection (MPIP) and Microsoft Sentinel, can really help with this. MPIP helps you discover and label sensitive data, so it stays protected wherever it goes, while Sentinel offers smart threat detection and keeps an eye on compliance.
When you use tools like MPIP as part of your CMMC 2.0 strategy, you make it easier to manage data protection policies and stay on top of requirements. It’s a powerful way for DoD contractors to boost security and stay compliant—without a headache.
Microsoft 365 GCC High: The Secure Cloud Environment for Federal Data
Think of Microsoft 365 GCC High as the protector of sensitive government information. This information is housed in a specialized cloud environment designed specifically to meet the stringent compliance needs of federal agencies and their contractors. It provides tailored controls to ensure data residency and sovereignty. This includes hosting all data within the US and restricting access exclusively to screened U.S. citizens.
GCC High offers enhanced security features such as:
• Advanced threat protection to detect and mitigate cyber risks,
• privileged access management to control and monitor elevated permissions, and
• secure enclaves that isolate highly sensitive workloads for added protection.
This environment is critical for organizations aiming to comply with key regulatory frameworks like DFARS, CMMC, and ITAR. For DoD contractors, migrating to Microsoft 365 GCC High not only ensures compliance but also delivers operational benefits including seamless integration with Microsoft 365 tools, robust security posture, and support for hybrid work models, making it an essential platform for managing controlled unclassified information (CUI) securely and efficiently.
Strengthening CUI Protection: The Role of Microsoft Purview, CMMC 2.0, and GCC High
Think of this trio as your go-to team for stopping Controlled Unclassified Information (CUI) spillage. Together, they create a strong, all-in-one security system designed specifically for Department of Defense (DoD) contractors and federal agencies. Microsoft Purview helps organizations automatically find, label, and protect sensitive data by using smart tools like automated classification, encryption, and data loss prevention (DLP) policies. This makes sure CUI is carefully controlled, both inside and outside the organization, which fits perfectly with the strict rules set by CMMC 2.0.
Then there’s GCC High, which adds an extra layer of protection by providing a secure cloud environment where data stays within the U.S. and access is limited only to trusted U.S. personnel. This setup helps meet important regulations like DFARS and ITAR. Together, these solutions offer continuous monitoring and quick responses to any security threats through GCC High’s Managed Security Operations Center (SOC) and Microsoft’s security tools, so potential leaks or insider risks can be spotted and handled fast.
On top of that, automated compliance reporting and audit-ready features make it much easier to stay on track with CMMC 2.0 certification by giving clear insights into how well controls are working. This combined approach builds a strong defense that not only cuts down the risk of CUI spillage but also makes compliance simpler for DoD contractors.
