Nightfall launches ‘Nyx,’ an AI that automates data loss prevention at enterprise scale
Nightfall AI launches Nyx, the first autonomous data loss prevention platform using AI to cut false alerts by 90% and protect enterprise data from insider threats and ChatGPT leaks.
Nightfall’s approach combines three AI-powered components: advanced content classification using large language models and computer vision, data lineage tracking that understands where information originates and travels, and autonomous policy optimization that learns from user behavior over time. The platform arrives as enterprises confront a new category of data risk: “ Shadow AI,” where employees use unauthorized artificial intelligence tools like ChatGPT, Claude, or Copilot for work tasks, often inadvertently exposing sensitive corporate information. The platform’s ability to provide contextual incident summaries — such as “Employee uploaded a file containing 200 customer PII records from Salesforce to personal Google Drive while working remotely” — represents the type of actionable intelligence that security teams need to respond effectively to threats.
