BI Intelligence expects 94 million connected cars to be sold in 2021 (with 82% to be connected cars), representing a compound annual growth rate of 35% from 21 million connected cars sold in 2016. Using ISTANA security Connected Cars can share car data totally secured and enable real-time emergency calls, immediate information that facilitates rescue services, and road hazard warnings that allow drivers to be informed and respond quickly. When it comes to convenience, car data can reduce breakdown risk/ downtime with predictive maintenance, concierge services can make light work of routine tasks (such as car washing and refueling) and connected infotainment can provide easy to-access entertainment.

Roman Brunner Chief Revenue Officer WISeKey said, "We are encouraged to witness strong interest for ISTANA for the connected car industry now also ranging across all related industry sectors. WISeKey's integrated Sales approach for IoT in particular opens up more opportunities out of our existing client base from Semiconductor as well as Trust Services. Provided as software or a managed service, ISTANA PKI offers a platform that meets the highest standards needed to issue, manage and validate digital credentials for IoT, and is scalable to support environments with hundreds of millions of devices by leveraging WISeKey's RoT strategy."

"As cars continue to evolve, essentially becoming motorized computers, they are vulnerable to the very same threats and attacks as home computers, laptops and smartphones. Unless appropriate cybersecurity measures are implemented, hackers can remotely access the vehicle's computer system, manipulate the brakes, engine, and transmission. Our technology is designed to help verify legitimate car systems, protect the data they create and avoid malicious hacking," said Carlos Moreira, CEO of WISeKey.
