Funk Software's customers included many of the world's largest corporations, institutions, telecommunications carriers, and internet service providers (ISPs); its products are licensed or resold by numerous leading manufacturers of Internet hardware and software.

In 2014, Juniper Networks sold off the business unit that was responsible for the legacy Funk Software enterprise products to New York-based Siris Capital.
