Nightfall Launches MCP Gateway to Govern AI Agents Learn more

Help us Build the Data Security Layer for the AI era

Data security hasn't caught up to how fast AI is moving. We're closing that gap — building the platform that lets the world's most ambitious AI companies innovate without exposing what matters most.

Our purpose

We believe data protection has to work intelligently and invisibly, or it won't work at all. Security teams shouldn't need to stitch together five different tools, wade through endless false positives, and still miss critical events. We're building toward a future where any company—from a 50-person startup to a Fortune 500—can protect their sensitive data across every SaaS app, every AI tool, and every endpoint without slowing anyone down.

Who we are

Founded by an early Uber Eats engineer and investors from Venrock and Bain Capital Ventures, we are a team of machine learning engineers, security practitioners, and product builders with experience spanning Uber, Harness, Microsoft, Symantec, Code42, Rubrik, and Skyhigh Security.

About Nightfall:

Nightfall is the AI-native, unified data loss prevention and insider risk management platform that protects sensitive data across SaaS apps, GenAI tools, email, endpoint devices, and more. Hundreds of customers, spanning AI innovators to top 10 banks, trust Nightfall to detect and stop data exfiltration at scale. Nightfall enables organizations to innovate freely without the risks of losing intellectual property or exposing customer data. Our agentic platform helps security teams regain their time by putting data loss prevention on autopilot. With automatic remediation, security violations can be resolved automatically before they become incidents, and end-users can be automatically trained and coached in the moment to self-heal violations that they introduce.

Nightfall is backed by leading VC firms including Bain Capital Ventures (Enrique Salem - former CEO of Symantec), Venrock (early investors in Cloudflare), WestBridge Capital, Pear VC (early investors in Dropbox and Doordash), and a cadre of cybersecurity leaders including Frederic Kerrest (founder of Okta), Maynard Webb (former COO of eBay), Ryan Carlson (President of Chainguard), Kevin Mandia (founder of Mandiant), and many others.
