The Problem

Legacy discovery fails at scale and buries‍ SecOps in false positives.

Legacy discovery and classification tools are riddled with false positives, carry complex on-prem architectures, and were never designed for petabyte scale.

Gap 01

60-80% undiscovered

Legacy DLP leaves most sensitive data unfound — PII in archived Slack channels, secrets in old repos, PHI in forgotten Drive folders.

Gap 02

Manual remediation

Millions of files, reviewed one at a time. Attack surface stays wide open while tickets pile up.

Gap 03

Months of tuning

Regex rules that still can't tell a real SSN from a phone number, or a live API key from a documentation example.

Customer quote

"Nightfall is reliable. When it says there's a detection, we trust that detection. You don't want to waste time chasing ghosts."
