We want to do a cleaning in our security policies because we have many rules not being used and many old objects not being used in our policies. My questions are:
-There is any way to know what policies are being used and howmany matches each rule have? in order to delete the rules not used....
-There is any way to know if any object is not being used in any policy?
Thanks a lot....

To know which rule are matched, onthe bottom of secu policy, you have "highlight unused rule", it will show you which rule never have been matched si nce the last palo reboot.
If you want you can create a custome report to knwo which rule are the most used.
for the object, for me there is nothing inside the palo to know if the object is currently used or not (or just try to delete 🙂 if it works, mean not used)
Maybe you can do that easilly but searching object name in your config file. It can be done automatically with small script

We use Firemon exactly for this purpose. There are no "onboard" tools available for your requirements

Unfortunately this is only working on a per Rule basis. What if one object of a certain rule has never been used but all other objects in that rule have been used ? This rule will be marked as "used" Rule which is only the half of the truth.
