About

What is Nightfall AI?

Nightfall AI is an all-in-one AI data security and data loss prevention (DLP) platform designed to prevent data leaks and exfiltration across various environments, including SaaS applications, generative AI apps, and endpoints. The platform offers comprehensive features such as data exfiltration prevention, data detection and response, and data discovery and classification. A key differentiator is Nyx, an autonomous AI agent that acts as a 24/7 DLP analyst, investigating incidents and shaping user behavior. Nightfall AI leverages AI and contextual understanding to trace data's full journey, providing holistic coverage and frictionless deployment through API-based integrations, lightweight agents, and browser plugins. It aims to reduce alert fatigue and enable autonomous protection, helping organizations secure sensitive data like PHI, PCI, and PII while allowing safe AI tool usage.

FAQs

How does Nightfall AI prevent data leaks to generative AI tools?

Nightfall AI uses browser plugins and endpoint agents to monitor AI interactions in real-time. It intercepts sensitive data like secrets, credentials, PHI, PCI, or PII from prompts, file uploads, and copy/paste actions before they reach AI platforms like ChatGPT, Copilot, or Gemini, ensuring data security without blocking innovation.

What makes Nightfall AI different from traditional Data Loss Prevention (DLP) solutions?

Nightfall AI differentiates itself with 95% detection accuracy using AI-based models and LLM file classifiers, compared to 5-25% for legacy DLP. It offers comprehensive coverage across SaaS, Gen AI apps, endpoints, and browsers, with frictionless API-based deployment in minutes, eliminating the operational overhead and blind spots of older systems.

Can Nightfall AI detect and prevent insider risks?

Yes, Nightfall AI detects malicious, opportunistic, and negligent insider risks by identifying unusual download patterns, unauthorized data movement, and sophisticated exfiltration attempts across multiple channels. Its AI-powered platform and data lineage tracking provide complete visibility and LLM-powered risk scoring to distinguish real threats from routine activity.
