This is a good suggestion!
Smart Provisioning was not used for these gateways.
We DO have: 'Enable IPS scheduled updates on the Security Management Server and Security Gateway'
'On Successful IPS update on the Security Management Server, install policy on the Security Gateway'
And I think that you are on the mark!
These lines appear to be the culprit ---> 'Access Control policy installation will be performed for Pre R80 gateways'
'Threat Prevention policy installation will be performed for R80 and above gateways'
All of our SMBs are on R77.20.87 - hence, the access control policy gets pushed. We really only want the Threat Prevention to push automatically, but it looks like we are stuck with it for now.
Thank you!!!
