Starting with Google Chrome 63, the Chrome web browser will add a feature to detect Man-in-the-Middle (MITM) attack that hijacks the user's Internet connection.
There is some concern that intercepting SSL and performing HTTPS proxy from the ProxySG is going to create an alert and warning in Chrome with the MITM feature enabled.
As long Chrome trusts the ProxySG certifcate by either installing the ProxySG certificate into Chrome's trust store or having the ProxySG's certificate signed by a trusted CA, then there will be no issues with Chrome's MITM detection when using ProxySG.
