Testimonials

“The management of device level certificates is a complicated beast and more complex than anticipated, particularly when scaling to hundreds of thousands. As a relatively small technical team, having a SaaS solution to integrate into was a big deal!”

CISO, Healthcare manufacturer

“KeyScaler provides device security in a constructive manner. We can authenticate the devices remotely, increase efficiency of the services and most importantly secure devices from cyber attacks.”

CTO, Energy Corporation

“Device Authority is a great company to work with. They have worked with us to resolve the issues and challenges we have faced with device security for both on-highway and off-highway implementations. Every curve ball I have thrown at them, they have managed to hit a home run for us.”
