We are trying to integrate Qualys and CyberArk. So far, it seems to work well on our internal network. However, we are having an issue with our Qualys scanner appliance in our DMZ not being able to connect to our CyberArk server on the internal network. I believe it may be a firewall rule and/or switch ACL. Is TCP port 1858 from the Qualys scanner IP address the only port needed to successfully retrieve and use the credentials from CyberArk to scan assets in the DMZ?
Thank you for your help in this matter!
