Do you mean to pass proxy credentials through Qualys TA for Splunk ? If yes, your question can be answered with following steps
It fetches Vulnerability Management (VM), Web Application Scanning (WAS) and KnowledgeBase (KB) data using modular input and indexes it which then can be searched using Qualys VM App for Splunk and/or Qualys WAS App for Splunk.
Once you have installed the TA on your splunk instance, go to Apps -> Manage apps . You see the TA listed as an application. Click on the setup link in the application row.
Add the API Server , user credentials, preferred detection settings and scroll down to the bottom of the page. You see a Proxy Configuration section. Enable checkbox for ' Use a proxy Server for Qualys API requests' and in the textbox below this checkbox add your proxy settings.
Format of the proxy should be as username:firstname.lastname@example.org:8080) if authorisation required. If no user exists for the proxy set as 10.10.10.2:8080 . Once done. save the form on setup page.
Restart your splunk instance and monitor logs at /opt/splunk/var/log/splunk/ta_QualysCloudPlatform.log. From the next run, it will use the proxy settings.
