What company sells Pegasus?

I'm curious to know, which company is responsible for selling Pegasus? Is it a well-known tech giant, or perhaps a lesser-known but innovative startup? And what exactly does Pegasus entail? Is it a hardware device, a software solution, or perhaps a service? I'm eager to learn more about the company behind this product and what sets it apart from its competitors in the market. Could you please shed some light on this for me?
