Problem

Legacy endpoint DLP and IRM tools cannot keep up

These tools weren't built for a perimeterless, SaaS and AI application-driven world.

They:
Miss data flowing to AI and SaaS apps
Create endless false positives
Frustrate employees with heavy agents and disruptive workflows
Require months to deploy and tune policies
​DMs, public channels, and private channels in Slack and Teams
​Drives, folders, and files in Google Drive and OneDrive
​Projects and repos in Jira and GitHub
​Outgoing emails in Gmail and Exchange
​And much more
The way employees work has fundamentally changed and new AI Apps are only exacerbating the problem. Meanwhile, your most sensitive data remains vulnerable to exfiltration.

Solution overview

Legacy DLP is broken. Stop real insider risks without the noise.

Comprehensive coverage

Stop data exfiltration across all egress vectors - AI applications, browser-accessed sites, desktop applications, unmanaged devices, and email to personal domains - without relying on legacy network DLP or web gateways. Our lightweight endpoint sensors secure every exfiltration threat vector.
Frictionless Deployment & Maintenance

Data Lineage

Track every piece of data from the point of exfiltration to its destination including all user actions in between. Our platform maintains visibility as data moves between users and applications, providing complete context across SaaS, AI apps and endpoints.
Frictionless Deployment & Maintenance

Monitor Shadow AI usage

Prevent data leaks by intercepting and automatically redacting sensitive information in prompts before it reaches AI platforms. Block inadvertent or deliberate uploads of corporate IP to both web and desktop AI applications while enabling safe innovation.
Frictionless Deployment & Maintenance

Prevent corporate espionage

Detect suspicious data movement patterns, unauthorized downloads to personal devices, email to personal domains and more in real-time. Block sophisticated insider threats before sensitive information leaves your organization, preserving critical intellectual property assets.
Frictionless Deployment & Maintenance

Accelerate forensics investigations

Reduce investigation time with complete visibility into data movement. LLM-powered risk scoring delivers actionable intelligence with full context, preview of content, quickly determining incidents with the highest risk that need to be remediated.
Frictionless Deployment & Maintenance

Legacy DLP cannot keep pace with data in motion

In today's fluid data environment, sensitive information moves at unprecedented speed across SaaS apps, AI tools, and endpoints. Legacy DLP creates a false sense of protection while your most valuable intellectual property silently slips through the cracks.

Nightfall offers a smarter, more scalable solution

Data Exfiltration Prevention

Enhanced accuracy

Nightfall’s industry-leading GenAI detection engine pinpoints PII, PCI, PHI, secrets, and credentials with fewer false positive alerts.
Data Exfiltration Prevention

Unparalleled visibility

Monitor sharing and permissions settings across SaaS apps to identify risks in real time.
Data Exfiltration Prevention

Automated workflows

Security teams can maintain a secure SaaS environment and ensure continuous compliance by responding to security issues the instant they pop up.
SaaS security posture

Nightfall leverages generative AI (GenAI) for a dynamic and responsive management approach to your SaaS security posture.

Monitor download events across SaaS apps and endpoints

Detect download events and uploads to unsanctioned locations in real time.
Set alert thresholds based on the number of downloads that occur in a certain time frame (e.g. “10 downloads in 24 hours”).
Reduce noise by tailoring policies according to:
​High-risk users, such as departing employees
​High-risk content, such as specific files, folders, or drives
​High-risk data types, such as PII, PCI, PHI, secrets, or credentials
Discover sensitive data

Get actionable alerts or respond in the Nightfall console

Configure alerts to Slack, Teams, Jira, email, or your SIEM of choice.
Review rich metadata for relevant users and content in the Nightfall console, including recent activity logs.
Take immediate action by suspending user access to SaaS environments.
Send custom messages to educate employees about policy violations either in-app or via Slack, Teams, or email.

How It Works

AI-powered detectors

Pre-trained LLM and Computer Vision models classify content such as Secrets & Credentials (NHI), Protected Health Information (PHI), Financial Information (PCI), and Personally Identifiable Information (PII).
Combine content classification with deep contextual awareness to stop high-risk exfiltration while allowing legitimate work to flow, reducing false positives by up to 95% compared to legacy DLP.

Light-weight endpoint sensors and browser plugins

Our endpoint sensors on MacOS, Windows are designed to utilize modern operating system APIs to securely process exfiltration events in the cloud to avoid any impact to user productivity.
Our browser plugins support all major browsers such as Chrome, Firefox, Safari, Edge and collect intelligence for any application, accessed via browsers, not available from any other sources.

Data Lineage

Your corporate IP doesn't just move between Google Drive, Slack and Salesforce – they transform along the way. Files get renamed, copied, converted, and shared with constantly changing permissions. Trace and monitor data movement.
See where it originated, how permissions changed, the content in the files and every transformation – from renaming to format conversion. When an exfiltration attempt occurs, you'll have the complete story: who downloaded the file, where it was copied, and all the critical steps that led to exfiltration.

Intelligent, policy-based automation

Tailor policies to high risk users, user groups synchronized via directory services such as Okta, Entra ID, Google Directory. Define lineage based policies to stop exfiltration of data originating from web-applications storing your crown jewels across all threat vectors.
Block file uploads or email, automatically redact prompts in Shadow AI applications, quarantine or encrypt outgoing emails, stop copy/paste, USB/print and more. Our platform allows you to define risk for your organization, automate actions, and educate employees in real time.

Quick forensic investigations

Simple, intuitive workflows to investigate incidents with complete context and data lineage to quickly isolate malicious exfiltration attempts. Flexibility to automate triage and response via SIEM/SOAR tool of your choice.
Security operations see the complete data lineage to trace how data moved across users and applications between source and all events leading up to the destination of the attempted exfiltration.
