You can do it using any SCM/ECM (software configuration management / enterprise configuration management tools) e.g. CFEngine, Puppet, Ansible or if even you can use MS SCCM. If IBM then BigFix is best.

In our environment we are using multiple tools with our own scripting to make get more and detailed results.
