2019 Internet Of Things 50: 10 Coolest IoT Security Vendors

IoT 50: Security

When the internet came to a halt for millions of people in fall 2016, the world would soon learn that a massive horde of unsecured Internet of Things devices were the culprit. A malware program called Mirai had been used to take over these devices and launch a large distributed denial-of-service attack against critical internet infrastructure. For the tech industry, this was a wake-up call for the importance of securing IoT devices against a growing number of attacks. With Gartner forecasting IoT security spending to grow to $3.1 billion in 2021, new offerings for protecting and securing devices are popping up on a regular basis, ranging in capabilities from threat monitoring to access control.
