### Discover and Protect Sensitive Data in Microsoft 365

Falcon Data Security for SaaS continuously discovers and classifies sensitive data across SharePoint, OneDrive, and Copilot as files are accessed, modified, and shared. Out-of-the-box data patterns identify regulated information such as personally identifiable information (PII), protected health information (PHI), and payment card data. Custom patterns help identify sensitive information unique to the business. 

AI-powered classification helps teams better understand sensitive information in context. The shared Falcon Data Security classification engine provides a consistent understanding of sensitive data across SaaS, endpoint, and cloud. This reduces the policy gaps created by disconnected tools, helps teams maintain one view of sensitive data across the business, and improves classification accuracy at scale while reducing manual effort.

Based on classified content, Falcon Data Security for SaaS can automatically apply and manage Microsoft Sensitivity Labels to help organizations consistently protect sensitive information. Teams can simulate labeling policies before enforcement, then apply labels that activate Microsoft 365 protections such as encryption, access controls, sharing restrictions, and watermarks while also restricting AI access. This creates a direct path from discovering and classifying sensitive data to protecting it.

### Secure Data Before AI Can Expose It

Microsoft Copilot can draw from information users are authorized to access across Microsoft 365, which makes existing data exposure and permissions increasingly important. Information that was once difficult to find can become much easier to surface through an AI interaction.

Falcon Data Security for SaaS helps secure the data Copilot can access by identifying sensitive information and applying Microsoft Sensitivity Labels and associated protections. This helps employees take advantage of Copilot while reducing the risk of sensitive information being unintentionally exposed through AI.

### Turn Data Discovery Into Risk Intelligence

Finding sensitive data is only the beginning. Falcon Data Security for SaaS combines sensitive content with exposure and location context to help teams prioritize meaningful risk, such as files exposed through anonymous links, data shared externally, overly broad access, or regulated information stored in unexpected locations.

Because Falcon Data Security is part of the CrowdStrike Falcon® platform, SaaS data findings feed into [CrowdStrike Falcon® Next-Gen SIEM](https://www.crowdstrike.com/en-us/platform/next-gen-siem/), allowing analysts to pivot from data risk into broader investigations alongside other security telemetry. This gives teams context to quickly focus on and act on the most critical exposures.

### Take Least Privilege Further with Just-in-Time Access

For highly sensitive data, knowing what the data is and protecting it isn't enough. Organizations also need to control who can access it and when. Falcon Data Security for SaaS integrates with [CrowdStrike Falcon® Privileged Access](https://www.crowdstrike.com/en-us/platform/next-gen-identity-security/falcon-privileged-access/) to bring just-in-time (JIT) access to sensitive data. Instead of maintaining standing access to sensitive SharePoint content, organizations can grant time-limited access to a specific user or group from an authorized device. When the approved period ends, access is automatically removed. 

By combining data classification and least-privilege access with just-in-time authorization, organizations can more tightly control who can reach their most sensitive information and reduce the risk created by persistent access.

## Modern Data Security for Wherever Business Happens

With Falcon Data Security for SaaS now generally available, CrowdStrike extends its modern data security approach deeper into the applications where business gets done every day. Across endpoint, SaaS, and cloud environments, Falcon Data Security helps organizations understand what data is sensitive, see how it moves and where risk emerges, and apply protection.

Microsoft 365 is the starting point for Falcon Data Security for SaaS, with plans to expand SaaS coverage over time. It’s another step toward a unified approach to securing sensitive data wherever it lives and moves.
