Why would an organization need to connect additional scanners to Tenable.sc?

Connecting additional scanners to Tenable.sc primarily enhances the organization's ability to cover a large network and conduct faster scans. In expansive environments, a single scanner may not adequately address the needs for comprehensive security assessments across all assets, especially in geographically dispersed locations or networks with significant device counts. By adding more scanners, the organization can distribute scanning workloads effectively, which not only accelerates the scanning process but also ensures that all devices are monitored and assessed for vulnerabilities efficiently and thoroughly. This setup optimizes the scanning infrastructure, leading to a more timely identification of vulnerabilities and better-informed security management decisions.

The other options do not focus on the primary reasons for adding scanners. Enhanced security management, for instance, is a broad concept that could involve various strategies and tools beyond just increasing the number of scanners. Compliance is certainly a consideration, but it is not the sole driving force for adding scanners. Additionally, user management capabilities are related to how users interact with Tenable.sc rather than the number of scanners connected to it. Thus, the need for larger coverage and quicker scanning cycles succinctly encapsulates the rationale for expanding scanning capabilities.
