Nightfall DLP Platform

Nightfall is the AI-native data loss prevention platform that protects sensitive data across SaaS applications, GenAI tools, email, and endpoints. The platform features 100+ AI-based models, LLM-powered file classifiers, and computer vision models that achieve 95% detection accuracy—far surpassing legacy DLP solutions stuck at 5-25%. Founded in 2018 and based in San Francisco, Nightfall has raised $60.3M from investors including Bain Capital Ventures, Venrock, and WestBridge Capital. The company serves hundreds of enterprises including Oscar Health, Splunk, and Exabeam.

Nightfall combines real-time content inspection with AI-powered data lineage tracking that traces information from source to destination, understanding risk based on context rather than just pattern matching. The platform deploys in minutes through API-based integrations, lightweight endpoint agents, and browser plugins—providing comprehensive coverage without disrupting productivity. Nightfall Nyx, the industry's first autonomous DLP analyst, automatically investigates security incidents, optimizes policies, and generates reports through natural language interactions, reducing false positives by 90% and cutting investigation time by 80%.

The platform consolidates legacy point solutions into a unified system, enabling customers to replace 3-5 separate security tools while improving protection. With self-learning policies, automated remediation, and end-user coaching for self-remediation, Nightfall delivers enterprise-grade DLP that works from day one. Organizations typically achieve 6x ROI within the first 90 days and complete deployment across their entire environment in under one month.
