Skip this if you're primarily concerned with on-premises data centers or need deep DLP integration into legacy enterprise applications; Nightfall's strength is modern, cloud-first environments where traditional perimeter controls don't apply. Mid-market and enterprise security teams managing data across SaaS, cloud, and GenAI environments should choose Palo Alto Networks Enterprise Data Loss Prevention for its AI-powered classification that actually catches what your data looks like, not just what you've labeled it. The platform covers over 1,000 data identifiers with trainable ML classifiers and Exact Data Matching supporting 2 billion-plus records, addressing the PR.DS and ID.AM functions that matter most when shadow data keeps appearing in places it shouldn't.
