Nightfall AI

Nightfall AI is a data loss prevention platform that describes itself as AI data security built to control AI agents and the data they touch. Nightfall's own pricing page, read directly, shows per user per year packaging with the dollar amounts stripped from the fetched text, so I cannot quote numbers. Foundation Edition is AI-native DLP for an entire organisation. Premier Edition adds AI agent security, with Tier 1 for up to 3 apps and Tier 2 for all supported apps. A Data Discovery and Classification add-on includes 150 GB, with paid annual packs of 1 TB, 3 TB, 5 TB and 20 TB. The FAQ says final pricing depends on user count and data volume and offers a free 7-day or limited-time proof of value rather than a self-serve trial, so treat it as contact sales.

Buyer data gives a rough idea: Vendr, based on 41 purchases, puts the median at $25,000 a year with a range of about $12,000 to $73,200. Directory listings on Capterra and similar sites showing $4 per feature per month look like placeholders, and G2 says Nightfall has not provided pricing. Nightfall's blog claims a record September and its largest deal ever, which is company marketing. A competitor-content caution applies as well, since Nightfall publishes reviews of rivals such as Cyera and Prompt Security, so read its comparisons knowingly. Ask whether agent security tiers count apps or users.

Nightfall AI suits security teams protecting data across SaaS apps and generative AI tools. Compare Cyera, Varonis and Lakera. Browse the Cybersecurity tools directory for more.
