Cost
Nightfall Complete is sold per user per year and bundles the data detection, response and exfiltration prevention features with a dedicated customer success manager and priority support; Complete + AI Agent Security is also per user per year and is tiered by coverage of up to 3 apps or all supported apps; a Data Discovery and Classification add-on includes 150 GB with paid annual steps at 1 TB, 3 TB, 5 TB and 20 TB; the amounts do not appear in the page itself, which prints the currency symbol without a number, and there is no free tier, only a 7-day proof of value, so contact the vendor for a quote.
Verdict
Best for enterprises deploying AI copilots and agents who need real-time data protection and compliance monitoring without manual incident response.
