What is Nightfall AI, and how does its technology work?

Nightfall AI is an AI-native data loss prevention platform that prevents sensitive data exposure and exfiltration across SaaS, endpoints, email, browsers, and AI apps. It uses over 100 AI-based models, LLM-based file classifiers, and computer vision models to classify content with high accuracy, combined with AI-based data lineage tracking to trace information from source to destination.

Which problems does Nightfall solve better than legacy DLP solutions?

Nightfall addresses three critical failures of legacy DLP: detection blind spots, operational overload, and deployment friction. Its AI-based detectors achieve significantly higher accuracy out-of-the-box compared to legacy solutions that rely on basic pattern matching and require extensive tuning.

How does Nightfall handle data exfiltration prevention?

Nightfall prevents data exfiltration by providing real-time visibility and control over sensitive data movement across AI agents, endpoints, and SaaS platforms. It blocks unauthorized actions such as uploading sensitive data to personal accounts or shadow AI tools, and reconstructs data lineage to flag potential exfiltration.

Who is Nightfall AI designed for?

Nightfall is designed for organizations handling regulated data, particularly those in industries like healthcare, financial services, legal, and manufacturing. It is suitable for cloud-based companies, internal communications platforms, and customer service environments where sensitive information is frequently shared.
