 In the 1990s CSG introduced the ACSR ( Advanced Customer Service Representative ) system . An extension to ACSR called ProfitNow ! was introduced in 2003 . ProfitNow ! used a consumer 's account data to advise customer service representatives on the likelihood of a caller cancelling their service or buying a new product . It was later turned into an online system with a user interface similar to Microsoft Windows at CSG.net. CSG purchased the Kenan FX software from Lucent Technologies in 2002 . Kenan software managed billing and ordering and provided middle @-@ ware to help various customer service and billing products integrate with each other . CSG NextGen was introduced for international markets , with support for multiple languages . In March 2014 , CSG added a cybersecurity suite to its product portfolio , under the name CSG Invotas . In November 2015 the Invotas unit was spun off into a separate entity . Invotas was acquired by FireEye in a transaction that closed February 1 , 2016 .
