Nightfall AI

Nightfall AI is an industry-leading, AI-native Data Loss Prevention (DLP) and insider risk management platform fundamentally built to secure sensitive data in the generative AI era. Founded in 2018 by Isaac Madan and Rohan Sathe, and headquartered in San Francisco, California, the company operates as a modern alternative to clunky, legacy DLP systems. Under the hood, Nightfall leverages over 100 pre-trained machine learning and computer vision models—delivering 95% detection accuracy—to continuously monitor, classify, and protect sensitive data like PII, PHI, PCI, and Non-Human Identities (NHIs). The platform integrates via APIs in minutes across major SaaS applications (Slack, Google Workspace, Salesforce, Microsoft 365) and uses lightweight endpoint agents to prevent intellectual property from leaking into shadow AI tools like ChatGPT and GitHub Copilot. Their primary target audience spans aggressive startups to Fortune 500 enterprises (such as Snyk and Genesys) who desperately need to overcome the "alert fatigue" of traditional security tools. What sets Nightfall apart in the fiercely competitive cybersecurity landscape is its autonomous AI DLP analyst, "Nyx," which automatically tracks data lineage, contextually investigates risks, and automates 80% of remediation through real-time employee coaching—slashing operational workload and reducing total cost of ownership by up to 10x.
