About Us

our vision is to
build a more secure
wireless world

We are reshaping device identity management for all wireless devices

Our truly innovative technology is pioneering a new form of authentication for wireless devices to prevent hacking, manipulation and deception.

Our services can protect billions of wirelessly connected devices that comprise the Internet of Things across all sectors.

We thrive on solving the unsolvable

We have already successfully developed solutions for many authentication gaps that, up until recently, were deemed unsolvable.

This has attracted influential early adopters and has accelerated our rapid growth into new markets.
