Go to Help > About to see information about the service. You'll see a list of Security Operations Centers (SOCs) identified with the IP addresses for service's external scanners under Qualys External Scanners, that you might need to whitelist, a list of SOCs identified with URLs for scanner appliances must contact under Qualys Scanner Appliances, plus additional service information for your reference.
Tell me about version info
You'll see the current web application version, the current online help version, and the current version of the SCAP application (when this is enabled for your subscription).
Tell me about External Scanners
External scanners are used for perimeter scanning. This functionality is available to all users to protect against external threats. External scanners must be able to access target IPs in order to perform network discovery and security audits on your perimeter. Multiple SOCs (Security Operations Centers) are located in various geographical locations as well as at customer sites with Private Cloud Platforms.
This section lists IP addresses for the service's external scanners located at the SOC where your account is located. Depending on your network, it may be necessary to add the scanner IPs to your list of trusted IPs, so that the service can send probes to target hosts when processing scans and maps.
This section also displays the current version number for the scanning engine and for the vulnerability signatures package.
Tell me about Scanner Appliances
When you have scanner appliances, you'll see a list of the SOC URLs appropriate for your account/location. Your scanner appliances must be able to contact these URLs on port 443. For Private Cloud Platforms, the URLs displayed are appropriate to your local on-site SOC.
What is a cluster?
This is the cluster ID within the SOC (Security Operations Center) where your account is located. Certain SOCs have clusters enabled. The cluster ID appears only when the SOC where your account is located has clusters enabled.
Tell me about identified services
