Qualys File Integrity Monitoring

Qualys File Integrity Monitoring is a cloud-based endpoint security solution designed to continuously monitor, detect, and alert on unauthorized changes to critical operating system files, registry entries, and system configurations across enterprise servers and endpoints. Operating through the lightweight Qualys Cloud Agent, it provides real-time detection of tamper attempts, unauthorized privilege changes, and malware persistence mechanisms without imposing substantial processing burdens on host systems.

The solution functions across on-premises physical servers, virtual machines, and cloud instances running Windows and Linux distributions across AWS, Azure, and Google Cloud environments. It integrates smoothly with central security incident repositories, SIEM solutions, and IT service management systems to generate immediate alerts and correlate change events with known maintenance tickets. Common operational use cases include meeting regulatory file integrity mandates, identifying suspicious administrative changes, detecting unauthorized binary replacement, and tracking modifications to critical system binaries and configuration repositories.

By combining continuous system file monitoring with centralized policy baselines, Qualys File Integrity Monitoring simplifies compliance adherence for standards like PCI DSS, HIPAA, and CIS benchmarks. Security analysts gain clear visibility into who modified what file and when, filtering out routine authorized updates from potential intrusions. The platform strengthens host-level defenses, streamlines audit validation, and reduces the operational effort needed to maintain secure server environments.
