[/vc_column_text][vc_column_text]Apache Unomi is a Java Open Source customer data platform designed to provide personalized customer experience. It can be integrated with CRMs, Applications, CMSs etc. And because of its efficient integration with other critical services, compromising Unomi is an ideal entry point into protected corporate networks.

Modus operandi
