Overview

The Qualys Cloud Agent offers organizations a comprehensive overview of their environment, encompassing both on-premises and cloud infrastructure, via a unified interface. It empowers organizations with vulnerability assessment, risk prioritization, and compliance capabilities. A single & customizable cloud agent delivers features like File Integrity Monitoring (FIM), Endpoint Detection and Response (EDR), and Patching

This agent requires no maintenance, as it automatically updates itself, which further minimizes the attack surface and enhances the overall security posture of your organization Furthermore, it continues to expand its application to a growing number of use cases each year.

As a cloud agent handles highly critical security data and then backhauls to the Qualys platform, it is essential to ensure the integrity and resilience of the cloud agent. With Self Protection, companies or admin teams don’t require any uninstallation or disablement of Cloud Agent or working too much with its configuration which eventually will lead to its seamless functioning.
