What is one of the reasons for defining different scan zones in Tenable.sc?

Defining different scan zones in Tenable.sc is primarily aimed at enabling coverage for multiple network segments. Scan zones allow you to organize and manage the scanning of distinct areas within your network infrastructure. By segmenting the network into different zones, security teams can ensure that scans are tailored to the specific configurations, security policies, and requirements of each segment.

This segmentation is particularly important in larger organizations where different departments or parts of the network may have various compliance requirements, risk assessments, or operational procedures. By assigning specific scan configurations to these zones, organizations can better manage the resources allocated to scanning and ensure that each zone is adequately monitored for vulnerabilities, ultimately enhancing their overall security posture.

In contrast, while improving compliance documentation, managing user roles, and enhancing data visualization tools are valuable goals, they do not directly relate to the primary function of scan zones, which is to facilitate comprehensive coverage across diverse network segments. This ensures that scans can be optimized according to the unique characteristics and needs of each network area.
