Nightfall AI

Nightfall AI is an AI-native data loss prevention platform that uses machine learning to discover and protect sensitive data, PII, credentials and secrets across SaaS apps, AI tools and endpoints. It targets enterprise security teams, adds AI-assisted incident triage, and uses quote-based pricing. Effectiveness depends on integration with an organization's specific stack and workflows.

Nightfall AI is a cloud-native data security platform that uses machine learning to detect and protect sensitive information, personal data, credentials and secrets, across the SaaS apps, AI applications and endpoints an organization uses. Rather than relying solely on regex rules, its ML detectors aim to reduce false positives while catching data that traditional pattern-matching misses. The platform has expanded from cloud DLP into broader data protection, including coverage for generative AI usage where employees might paste sensitive data into chatbots. In 2026 the company leaned into AI automation with features like an autonomous DLP analyst that helps triage and respond to incidents, reflecting a shift toward AI-assisted security operations. Nightfall is an enterprise-oriented product: pricing is quote-based, typically starting in the low five figures annually and scaling by users, data volume and API usage. Buyers should scope it against their specific SaaS stack, compliance requirements and incident-response workflows, and plan for a security-procurement process rather than self-serve signup.
