What is Nightfall AI?
Nightfall AI is an AI-native data loss prevention platform that detects and prevents sensitive data exposure across SaaS applications, endpoints, email, browsers and AI tools. It tracks data lineage to block unauthorized movement of sensitive information, including to shadow AI tools such as ChatGPT, and includes an autonomous AI agent (Nyx) for triaging DLP alerts. Nightfall extends coverage to AI agent security, offering hooks-level interception, prompt injection detection and visibility into MCP server usage. It is built for security teams at technology, healthcare, financial services, legal and manufacturing companies that need to prevent data exfiltration as employees and AI agents increasingly move sensitive information through SaaS tools, browsers and emerging AI workflows, and that want automated remediation rather than purely manual alert review.
