Nightfall.ai is a data loss prevention (DLP) and insider risk management platform that uses AI to identify sensitive information and track its movement. It is designed for businesses ranging from startups to large enterprises, specifically those using a variety of SaaS tools and generative AI applications.
The software helps security teams detect and respond to data exfiltration and inadvertent exposure. It supports the identification of PII, PHI, PCI, and secrets across cloud environments and employee devices using LLM-powered classifiers and computer vision models.
Buyers should consider which specific coverage they need, as the platform offers different tiers for data detection and response versus exfiltration prevention. Buyers should confirm how the per-user annual pricing aligns with their total employee count across connected apps.
