File Integrity Monitoring (FIM) by Qualys is a cloud-based security solution that detects, tracks, and safeguards files and registry objects from cyber threats across global IT systems. Operating as a component of Qualys' Enterprise TruRisk Platform, it monitors operating systems in real-time using Cloud Agents, providing centralized logging and management of events while correlating and tracking change incidents. The solution implements noise cancellation technology that reduces false alerts by 90 percent or more while identifying critical changes, incidents, and risks stemming from both normal operations and malicious events. It validates file integrity to monitor files, enforce change controls, fulfill compliance requirements including GDPR, CCPA, SOX, HIPAA, and PCI DSS 4.0, and detect compromises across diverse cloud and on-premises environments through a single agent and central dashboard.
