During deployment of Advanced Threat Protection (ATP) Platform in an environment with a proxy, or after adding a proxy in an environment where ATP Platform is already deployed, the system status begins to show "ATP is Critical" in red.
ATP does not support the interception of its SSL communication to and from the Symantec licensing servers. This behavior is by design.
Provide a network route between the ATP platform's MGMT interface and the internet where SSL traffic is not intercepted.
For proxies not published by Symantec, please consult with your manufacturer or vendor for a workaround. You may need to consult Appendix D of the Symantec™ Advanced Threat Protection 3.2 Administration Guide, available here:
To workaround this behavior within Symantec ProxySG
IP_OF_ATPis the actual IP address of the ATP appliance.
To add the ATP server IP as a source IP to the proxy bypass list within a transparent ProxySG
To add a TCP Tunnel service for ATP to a transparent ProxySG
To disable the Network Proxy settings within the UI of the ATP Platform
