The Company

We’re a IoT security company focused on protecting M2M communications for Smart Cities and Mobility. Headquartered in Belfast, with offices in London and The Hague, we have developed solutions that protect devices’ identities. With an increase of inherently insecure networks coming online with the boom of IoT, our solutions safeguard critical machine-to-machine communication integrity and data provenance, creating trusted connections, even in untrustworthy networks.

Since our formation, we have been moving at a high speed. We have been named as the Top Cyber Security company in NI, ranked 4th in NI’s Top 50 Tech companies, and nominated for Start-up of the Year. We’re also one of the Top 3 Hottest Space Tech start-ups in Europe! Our ground-breaking technology has led us to be the only cybersecurity company to win a place on Zenzic’s CAM Scale-Up Programme, and we are proud alumnus of Tech Nation’s Cyber 2.0, Seraphim Space Camp and YES!Delft. We are also the first (and only!) NI cyber security company to be a part of the NCSC Cyber Accelerator.
