Which of the following is a not a type of scanner under Nessus deployment?

The correct answer is that "SecOps scanner" is not a recognized type of scanner under Nessus deployment. In the context of Nessus, there are several established types of scanning solutions that are officially supported and widely used within the Tenable ecosystem.

Tenable.io is a cloud-based solution that provides vulnerability management services, combining various features of Nessus scanning within a unified platform. This is part of the broader Tenable suite that integrates multiple capabilities into one system.

Tenable Core, when paired with Nessus, forms a powerful local deployment solution that allows organizations to conduct vulnerability scanning and management on their own infrastructure. Nessus agents serve as lightweight alternatives for scanning assets that may be off-network or require continuous monitoring without being continuously connected to a central scanning system.

Conversely, the term "SecOps scanner" does not correspond to any specific product or deployment method recognized within the Nessus lineup, which explains why it is the correct choice in this scenario. This highlights the importance of understanding the specific tools and types of deployment available within the Tenable ecosystem while recognizing that not every term may pertain to their offerings.
