Which of the following is NOT a Tenable product for vulnerability management?

The reason "Qualys" is not a Tenable product for vulnerability management is that it is a separate company offering its own suite of security solutions, which include vulnerability management among other services. Tenable, on the other hand, provides its own products specifically designed for identifying, assessing, and managing vulnerabilities across various environments.

Tenable's products, such as Nessus Professional, Tenable.io, and Tenable.sc, are developed to offer organizations the tools they need for effective vulnerability assessment and management. Nessus Professional is known for its robust scanning capabilities and is widely used for identifying vulnerabilities in various systems. Tenable.io is a cloud-based solution that focuses on vulnerability management across cloud and on-premises assets, while Tenable.sc provides advanced analytics and reporting capabilities.

Recognizing these distinctions between Tenable's offerings and competitor products like Qualys is essential for understanding the landscape of vulnerability management tools.
