Nightfall
AI data security and data loss prevention platform.
Nightfall is an AI-native data loss prevention and data classification platform that monitors and controls sensitive data movement across AI agents, MCP servers, endpoints, SaaS applications, and email. It addresses the challenge of data exfiltration in environments where both people and autonomous agents move data, providing real-time detection, blocking, and investigation with full lineage from origin to destination.
The platform includes Data Exfiltration Prevention, Data Detection & Response, Data Discovery & Classification, and MCP & AI Agent Security modules, along with Nyx, an autonomous DLP analyst that investigates incidents and tunes policies. AI features include pre-trained ML detectors, LLM classifiers, dynamic risk scoring, prompt injection interception, and forensic session replay. Coverage spans macOS, Windows, and major browsers, with integrations for Slack, Google Drive, Gmail, Jira, Confluence, Salesforce, Microsoft Teams, OneDrive, Exchange Online, SharePoint, Notion, and Zendesk.
Nightfall is built for security teams and organizations of varying sizes, from startups to large enterprises, across industries including technology, healthcare, financial services, legal, and manufacturing.
