AI data security and DLP to detect exposure and stop exfiltration across SaaS apps, AI tools, browsers, endpoints, and email
What is Nightfall?
Nightfall is an AI data security and data loss prevention platform that helps organizations detect sensitive data exposure, understand how data moves across systems, and stop exfiltration across SaaS apps, AI tools, browsers, and endpoints. The product positioning emphasizes real-time visibility and control for modern environments where legacy DLP tools struggle to keep up.
The platform combines SaaS API integrations, endpoint controls, browser-based enforcement, AI content classification, and data lineage tracking. Nightfall’s product pages also show packaged options for Data Detection & Response, Data Exfiltration Prevention, Nightfall Complete, and AI Agent Security, plus add-ons for data discovery and classification and a developer platform for custom applications.
What can Nightfall do?
AI content classification
Uses AI-based detectors, file classifiers, and content inspection to identify secrets, credentials, PII, PHI, PCI, source code, and other sensitive content with context-aware classification.
AI data lineage tracking
Reconstructs how a file or data item moved from source to destination so policies can evaluate risk based on data movement, not just keywords or patterns.
Exfiltration prevention controls
Blocks or limits risky actions such as uploads, downloads, copy/paste, clipboard use, printing, USB transfer, and unauthorized sharing depending on the plan and policy.
Autonomous DLP analysis
Adds agentic investigation with Nyx, which can review threats, optimize policies, and generate reports through natural language interactions.
AI agent security coverage
Extends protection to AI workflows with hooks for Cursor, Claude Code, VS Code, MCP discovery, and Claude Enterprise monitoring on supported plans.
Use Cases
“SaaS data leak prevention”
Monitor Slack, Google Drive, Gmail, Microsoft 365, Jira, Confluence, Salesforce, Zendesk, and Notion for sensitive data exposure as content is shared or updated.
“Endpoint and browser exfiltration control”
Block uploads, downloads, copy/paste actions, print jobs, and USB transfers on endpoints and supported browsers when users attempt to move crown-jewel data.
“Shadow AI protection”
Detect secrets, credentials, PII, PHI, PCI, source code, and related sensitive content in AI interactions and stop unsafe sharing with tools like ChatGPT, Copilot, Gemini, Claude, Perplexity, and others.
“Data lineage investigation”
Track how files move from one system to another and use lineage to flag suspicious paths such as personal cloud storage sync or renamed files leaving approved systems.
“Audit and remediation workflows”
Standardize policy and reporting for compliance and SecOps teams that need evidence for audits such as SOC 2, PCI DSS, and HIPAA without relying on manual review alone.
