Review the new features introduced to Enterprise Data Loss Prevention (E-DLP) in December
2025.
Strengthening MPIP Labeling Security
December 9, 2025
Microsoft periodically makes changes to Purview (formerly AIP) labels that can cause
your existing Enterprise Data Loss Prevention (E-DLP) file property data patterns to fail to detect
sensitive documents. When these detection mechanisms fail, sensitive data labeled
with Microsoft Purview labels might bypass Enterprise DLP inspection, which can
lead to compliance risks and unintended data exposure.
Strengthening MPIP Labeling Security significantly improves the resiliency and
reliability of Enterprise DLP patterns that inspect for Purview labels. Enterprise DLP now has a more robust detection mechanism for file property data patterns that detect
for Purview labels. This shields your policy rules against labeling changes
initiated by Microsoft updates, ensuring your detection patterns remain effective
without requiring frequent, reactive updates from your data security administrators.
This strengthened consistency and stability saves your team significant time and
resources by eliminating the need for constant monitoring and updating, ensuring
consistent data security enforcement despite changes from Microsoft.
Enterprise DLP Integration with Prisma Browser
December 15, 2025
The Enterprise Data Loss Prevention (E-DLP) and Prisma Browser Integration solves the challenge
of maintaining consistent data protection across different security products by
unifying data classification, management, and visibility. Instead of duplicating
effort, your data security administrators can leverage their investment in creating
and tuning data profiles and classifiers across both Enterprise DLP and Prisma Browser. The integration dynamically synchronizes profiles and
classifiers, ensuring updates made in Enterprise DLP automatically reflect in
Prisma Browser rules.
For Prisma Browser, your data security administrators can configure a Enterprise DLPdata profile for Local
Detection or for Cloud-Assisted detection. Data profiles
configured for Local Detection support only regex-based
detections. Prisma Browser evaluates traffic that matches against
Local Detection data profiles directly on the
browser and only Prisma Browser can use Local
Detection data profiles. Conversely, your data security
administrators can configure Enterprise DLP Cloud Assisted data profiles with
all supported detection methods. Prisma Browser intelligently routes
classification requests based on profile type, optimizing security, and
performance.
This unified approach extends protection beyond traditional file transfers to include
last-mile controls like clipboard operations, screen sharing, typing guard, and data
masking. Your organization gains comprehensive data protection with reduced
administrative overhead while benefiting from deployment flexibility that can reduce
dependency on Explicit Proxy for SaaS apps.

Regional Storage for Evidence Storage
December 16, 2025
When operating across multiple geographic regions, your organization needs to ensure
that sensitive data remains within specific regional boundaries to comply with local
data protection laws. Regional Support for Evidence Storage enables your data
security administrators to configure region-specific evidence storage buckets for
Enterprise Data Loss Prevention (E-DLP) incident evidence files, replacing the previous
single-bucket limitation. Your data security administrators can now designate
specific AWS, Azure, or SFTP storage buckets for each incident region, ensuring that
Enterprise DLP automatically stores evidence files from DLP incidents in
their appropriate regional storage location.
Your data security administrators can now manage evidence storage on a
region-by-region basis, configuring each bucket with the appropriate cloud provider
credentials and permissions. When Enterprise DLP detects an incident, it
automatically routes the evidence file to the storage bucket assigned to that
incident's region. This preserves the chain of custody while maintaining compliance
with regional data sovereignty requirements. If a region has no configured storage
bucket, Enterprise DLP won't provide the option to download evidence for
incidents in that region, ensuring strict adherence to your data residency
policies.
Enterprise DLP continuously monitors the connection status of your configured
regional buckets and notifies your data security administrators immediately if any
connection issues arise. These notifications include detailed diagnostic information
about the connection failure, allowing quickly remediation of any storage
configuration problems. Your data security administrators can also manually test
bucket connections at any time to verify your storage configuration is working
properly. This comprehensive approach to evidence storage management provides the
flexibility and control your organization needs to maintain regulatory compliance
while effectively managing security incidents across your global footprint.
