All users with Smart Connect v1.5.x and older must upgrade to Smart Connect latest version.
As of December 7th 2016, Smart Connect agents v1.5.x and older will not longer be capable of authenticating to our service. In such a scenario, the web traffic from the Smart Connect agent will be routed directly to the destination website without any inspection by our Web Security.cloud Service placing them at potential risk from web based malware.
Symantec does recommend to upgrade Smart Connect on users' computers when a new version of the software is released.
If you are provisioned with the Web Security Smart Connect roaming service, you can download the latest version of Smart Connect from the portal by going to the Tools tab > Downloads > Smart Connect Agent. You must uninstall the any previous version of the Smart Connect agent and then install the new version.
For any other software deployment management software, consult the corresponding documentation.
Please make sure to take the necessary measures to make sure that your users have internet connectivity during this upgrade.
