Qualys Performance Tuning Series: Remove Stale Compliance Data for the Best Performance

Qualys presents a Stale Data Utility that automates the detection and purging of outdated compliance and scan data from assets and technologies not refreshed within a user-defined period, improving data accuracy, compliance visibility, and performance. The post explains how dynamic IT and compliance changes cause stale data, outlines the impacts (inaccurate reports, increased MTTR, storage bloat), and recommends purge thresholds (greater than 5× scan frequency or 30 days) with rules for assets, technologies, policies, controls, and expired exceptions. It also describes an initial support-assisted rollout followed by scheduled automated housekeeping.
