Software Developer - Xaptum

What is Xaptum?

Xaptum is a collection of messaging services with federated security, available as a cloud computing platform for the internet of things. It enables IoT device authentication, authorization and auto-configuration for full-duplex messaging over a single TCP connection. The product is a reference implementation of GSS-API [RFC 2743]. Service providers, creating applications and devices for the internet of things can leverage Xaptum’s federated messaging infrastructure for simple, secure and scalable deployment using our open source client libraries.

Say What?!

We are developing the infrastructure required to ensure smooth and secure communications between connected devices and the cloud applications that monitor them. Xaptum then sells the rights to use its technology to third-parties including telecommunications companies and manufacturers of connected devices, allowing them to focus on what they do best: making kitchen appliances, air conditioners, garage doors, or whatever else you can think of.
