## Executive Summary

Nightfall markets cloud data loss prevention for the AI era, yet the newest funding and named customers in the reviewed record date to 2022. The product is broad and modern: machine-learning detectors scan SaaS apps, endpoints, browsers, and AI prompts for personal data, payment records, and secrets, and a new agent named Nyx triages alerts. But the strengths that would keep a rival out are ones every data-security competitor shares, a hard detection problem and a sticky compliance buyer, while nothing in the record shows an exclusive dataset, a managed service, or a certification wall Nightfall alone holds. A buyer should ask for current customers and growth, because the public record does not show them.
