Overview

Nightfall AI offers an AI-native Data Loss Prevention (DLP) platform designed to prevent sensitive data exposure and exfiltration across a wide range of environments, including SaaS applications, endpoints, email, browsers, and AI applications. It leverages over 100 AI-based models, LLM-based file classifiers, and Computer Vision models to achieve high accuracy in content classification (95%), significantly surpassing legacy DLP solutions. The platform also incorporates AI-based data lineage tracking to trace information from its source to destination, assessing risk based on context rather than just content patterns. Nightfall AI aims to address the shortcomings of traditional DLP by providing real-time visibility and control over data movement, particularly in the context of AI agents and modern cloud environments. It helps organizations maintain compliance with regulations like HIPAA by automatically discovering and protecting regulated data (PHI).
