Nightfall Product Updates & News: May/June 2025

Sensitive data is zooming across dozens of platforms every day, from Slack to email to gen AI platforms and many more sources. We all need this connectivity to stay productive, but the connectivity also creates countless opportunities for data to slip through the cracks. A single misplaced email attachment can end up exposing confidential information in a matter of seconds. And worst of all, without a data loss prevention (DLP) solution to help manage that risk, there’s not much end users can do once the data escapes a secure environment.

At Nightfall, we understand that there’s humans facing real consequences and striving to protect data that means everything to other humans. That’s why we're obsessed with building AI-native DLP that works as hard as you do to keep your data safe.

Here’s the latest news and updates from Nightfall at a glance:

• Improved Nightfall dashboard is now available for early access
• Introducing our newest integration: Microsoft Exchange Online DLP support
• Automated learning is powering most Nightfall detection models
• Enhanced data exfiltration monitoring enables improved data protection across macOS and Windows with expanded monitoring, content-based blocking, and faster exfiltration tracking
• Quick hits on new features from Nightfall—audits for Salesforce and four new driver’s license number detectors for Southeast Asian countries 

Read on for an in-depth look into each of our new features and updates.

Update: Improved Dashboard in Early Access

Nightfall AI's new dashboard delivers unified insights that spotlight critical risks, provide real-time actionable intelligence, and enhance team efficiency through automated workflows. Quickly identify high-priority threats with minimal clicks, leverage industry benchmarks to drive proactive tuning, and demonstrate clear ROI—all while delivering comprehensive analytics across products that boost satisfaction, and improves remediation rates. 

Update: Exchange Online DLP Support

Protect your sensitive data across Microsoft Exchange Online with Nightfall's latest integration. Our AI-powered detection now extends to your email communications with these features:

• Real-time sensitive data detection in outgoing emails and attachments
• Automated remediation with support for Block, Quarantine and Encryption to prevent exposures
• Seamless integration in minutes with your existing Microsoft 365 environment
• Comprehensive visibility into data exfiltration risks via agents for macOS and Windows

Update: Automated Learning Now Powers Most Detection Models

We’re thrilled to share a major milestone: Automated Supervised Learning (ASL) is now live across the majority of our detection models. This marks a significant leap forward in our AI platform’s maturity.

Each week, ASL automatically incorporates your real-time feedback and new annotated samples, retrains our models, benchmarks performance, and deploys improvements—no manual steps required. The results: sharper detection, fewer false positives, and continuously improving precision you can trust.

This breakthrough accelerates innovation, instantly scales improvements across all customers, and frees our team to focus on the next frontier of AI-powered data protection.

Update: Data Exfiltration Monitoring

We’re excited to share our latest release, which delivers comprehensive data loss prevention enhancements across macOS and Windows endpoints and significantly expanding protection capabilities and achieving feature parity between platforms. 

Here’s a list of what you can do with all the new features from Nightfall:

• Images and screenshots are now scanned for text content when copied, expanding protection beyond just text-only clipboard content on macOS.
• Blocking clipboard paste actions based on user, group, source and destination is now available on macOS, bringing block capability to parity with browser and cloud storage sync upload.
• Blocking file uploads based on content is now available on macOS enabling users to take action based not just on who is transferring data, where it is coming from, and where it is going, but also what is being transferred.
• File, path, subpath, and file extension exclusions are now available for macOS and allow users to fine-tune your endpoint monitoring and enforcement strategy by silencing known-good activity.
• Cloud storage app monitoring is now available on Windows, bringing coverage parity across macOS and Windows endpoints: browser uploads, copy/paste, and cloud application sync.
• Windows now supports full lineage scoping with new lineage source support, bringing lineage tracking capabilities to parity with macOS.
• Exfiltration event APIs are now available to programmatically Search Exfiltration Events, Fetch Exfiltration Events, Fetch Event Details, Fetch Asset Activity, and Fetch Actor Activity.
• Exfiltration event creation is now up to 90% faster across SaaS and endpoints, thanks to significant performance improvements.

Quick hits on new Nightfall features

We’re also excited to announce expanded audit capabilities for Salesforce and new driver’s license detectors for Southeast Asian countries:

Audits for Salesforce

Nightfall users can now audit historical data with PHI, PII, PCI, or secrets and keys going back years in Salesforce with the ability to filter by date range, objects and fields. Review results and automate remediation to redact or delete via the console.
