Users see a pop-up window requesting credentials when the WSSA is configured with proxy settings to contact to the Web Security Service (WSS). The local proxy is also configured with web authentication and intercepts the initial request to ctc.threatpulse.net. Then the local proxy requests the WSSA to authenticate.
Users receive an authentication pop-up window similar to the following:
Web Security Service
WSSA
To bypass the authentication request pop-up, install the following policy into the proxy Local policy file.
On the ProxySG appliance:
<Proxy>
url.domain=ctc.threatpulse.net authenticate(no) ALLOW
