Nightfall AI
AI-native DLP for SaaS, endpoints, browsers, and GenAI prompts that learns from investigations.
Proof of life. Launched Nyx, an autonomous DLP copilot, July 2025
Nightfall watches Slack, GitHub, Google Drive, email, and endpoints for PII, secrets, and IP using ML classifiers instead of a regex museum. The Nyx copilot investigates incidents, tunes policies, and remembers past cases so analysts are not restarting every ticket. Coverage now includes AI coding tools and CLIs, which is where data leaves the browser and most DLP goes blind.
