The security rules functionality of Qlik Sense is far superior to Qlik SaaS. The ability to be able to automatically create rules to automatically assign privilege to users/groups in specific spaces is very useful and should be included in Qlik SaaS. This coupled with the ability to audit objects/users is very useful for sys admins managing the site, or dealing with issues. These functions also help with SaaS migration as currently even user groups require manual privilege administration on a per space basis.
