Which vulnerability management tool supports internet-wide scanning and internal intranet scanning via an on-premises appliance?

• A. Qualys
• B. Nessus
• C. OpenVAS
• D. Retina

Answer: (A)

Vulnerability management tools that cover both external internet-facing assets and internal networks typically use a cloud platform paired with on-premises scanning appliances. Qualys fits this model by offering scanner appliances that you deploy inside the network to handle internal intranet scans, while the Qualys Cloud Platform takes care of internet-wide scanning for public-facing assets. The data from the on-premises appliance is centralized in the cloud, giving a single view of risk across both internal and external assets. This integrated approach—internal scanning via an on-premises appliance plus internet-wide visibility through the cloud—is what makes Qualys the best fit here.
