Qualys Cloud Agent Passive Sensor is a security tool that leverages passive network discovery capabilities to expand internal attack surface coverage. The sensor integrates with Qualys CSAM (CyberSecurity Asset Management) and functions as an extension of the Qualys agent to detect assets and potential security risks. It performs automated network discovery and profiling of systems without requiring information about network design, delivering results faster than other solutions including traditional scanning methods, agents, and API-based discovery approaches.
