Case Study: a leading fintech company protects logs and stack traces with Nightfall

How a leading fintech company protects logs and stack traces with Nightfall

A leading fintech company that powers billions of dollars in daily transactions was challenged by the significant risk of sensitive data like PII and secrets leaking into its application logs and stack traces. Its cloud-native, API-driven infrastructure made traditional security ineffective, and the basic regex-based tools in its observability platforms generated a high volume of false positives, wasting valuable security team time. To address this, the company implemented Nightfall's Firewall for AI.

By integrating Nightfall's API, the company automated the inspection and redaction of sensitive data from over a million logs daily before they reached its SIEM. This solution provided highly accurate detection with a low false positive rate, eliminating manual work and allowing the security team to remove native controls from other tools. The implementation by Nightfall was straightforward and delivered immediate results, significantly reducing financial and breach risk while enabling the security program to scale through automation.
