leading-edge, either on-site from their location or from the provider's

Although you might hear multiple definitions in the marketplace,
Futurestep defines RPO as a highly customized, fully integrated single-source
solution in which expert consultants manage all of a client’s human
capital requirements, either on-site from their location or from the
provider’s. The goal is to attract the highest-quality talent while also
bringing improved processes and efficiencies to the organization. To do
this, providers leverage brand, leading-edge technology, proven
diagnostic and metrics, and their global reach.

on site - where they are set up; where their place of business is.
leading edge technology - the latest most advanced technology.

Thank you Ronbee.
I understand the words individually but I cannot understand the emboldened parts (either on-site ..........from the providers) together?

Can you explain them in a simple way to me?

It looks like jargon to me. Whatever happened to plain English?

The words "on site" simply refer to their location. The words "from the provider's" refer to the provider's location. (I am not sure what "provider" means in this context, but additional context would probably make it clear.)
