Qualys Passive Scanners offer an efficient solution for continuous network monitoring and vulnerability detection without the need for active scanning. These scanners passively observe network traffic and identify potential security risks by analyzing real-time data flows. They are crucial for organizations looking to minimize system disruption and network load while ensuring comprehensive vulnerability management.

Unlike traditional active scanning methods, passive scanners work by listening to network traffic and inspecting it for vulnerabilities. They do not interact directly with the systems being monitored, which reduces the risk of affecting system performance. This makes passive scanning ideal for environments where network stability is critical.

Key Benefits of Qualys Passive Scanners:

  • Minimal impact on network performance
  • Real-time detection of vulnerabilities
  • Continuous monitoring without disrupting operations
  • Efficient detection of threats without active probing

Passive scanners work by collecting data from network packets, analyzing them for vulnerabilities, and comparing them against a comprehensive database of known security issues. They also allow for seamless integration with existing Qualys solutions, providing organizations with a comprehensive view of their security posture.

Important Points:

Passive scanners are ideal for organizations that cannot afford system downtime or network disruptions.

To enhance the functionality of passive scanning, Qualys offers several deployment options. Below is a comparison of the available deployment methods:
