Case Study: Ellucian achieves instant visibility and Slack data protection with Nightfall

Ellucian leverages Nightfall for Data Security on Slack

Ellucian, a leading higher-education software and cloud services provider with about 3,000 employees and serving over 2,500 institutions, faced the challenge of preventing sensitive data leaks across unpredictable, multi-channel communications—starting with Slack, which has no native DLP. Josh Sosnin, Ellucian’s CISO, selected Nightfall’s DLP for Slack to gain visibility and control over sensitive information flowing among employees.

Nightfall’s bot integrated into Slack in minutes and uses machine learning with over 25 PII detectors to scan messages and files, classify sensitive data, and enable manual quarantines or automated workflows. The deployment gave Ellucian “instant visibility” and added accountability across its 3,000-person workforce, helped confirm policy compliance, and—backed by Nightfall’s responsive support—prompted plans to extend Nightfall beyond Slack.
