# Create a content policy to filter network file content
Global Secure Access supports network content filtering through content policies. This feature helps you safeguard against unintended data exposure and prevents inline data leaks to generative AI applications and internet destinations. By extending data protection capabilities to the network layer through Global Secure Access, network content filtering enables your organization to enforce data policies on network traffic in real time. You can discover and protect files shared with unsanctioned destinations, such as generative AI and unmanaged cloud apps, from managed endpoints through browsers, applications, add-ins, APIs, and more.
The network content filtering solution brings together Microsoft Purview's data classification service and the identity-centric network security policies in Global Secure Access. This combination creates an advanced network-layer data security solution, Data Loss Prevention (DLP), that's identity-centric and policy-driven. By combining content inspection with real-time user risk evaluation, you can enforce granular controls over sensitive data movement across the network without compromising user productivity or security posture.
> [!NOTE]
> Basic content policy (block or allow by file MIME type) is generally available. The **Scan with Purview** action in content policies is currently in preview. This information relates to a prerelease product that might be substantially modified before release.
