Trust as a Concept:
Open Source

Trust is more important than ever before in today's data-driven world. Especially now, in the post-PRISM landscape, open source software delivers a crucial benefit: transparency. Security against back doors. Open source interoperability and customizability ensure that service providers do not get locked-in to proprietary models that limit choice, flexibility and trust from the people that matter most: their customers.

These principles apply to OX App Suite™, our provider-grade customer engagement platform, which enables service providers to improve customer retention, thus freeing them up to drive new revenue streams with their customers.
