It is possible by testing the Kaseya intennet concerning what was reported in the package provided by the service provider of broadband?
You could build a custom field, run a test from speedtest.net, gather the results, then compare.
I can't think of a built in tool to do so though.
Just getting the ISP alone is going to require some kind of database. You probably don't want to pay for that though (either from a third-party or in-house development).
Here are some examples for the ISP part alone.
I think you are asking for the subscribed package based on speed test results which is going to be even more difficult to achieve.
Good luck if you decide to attempt any of this...
As would be the setting for the present situation is Kaseya?
