The need for better IoT security capabilities is greater than ever before, and that isn’t expected to change any time soon.

This ongoing necessity to monitor and protect against threats to a wide range of connected devices was recently underlined by the U.S. Government Accountability Office, which said in December that the country’s 16 critical infrastructure sectors “face increasing cybersecurity threats.”

It’s not just individual agencies that see the problem. In early March, the Biden administration called for a greater focus on developing secure IoT devices as part of its new National Cybersecurity Strategy, building on previous legislation and other government efforts addressing the issue.

“Too often they have been deployed with inadequate default settings, can be difficult or impossible to patch or upgrade, or come equipped with advanced—and sometimes unnecessary—capabilities that enable malicious cyber activities on critical physical and digital systems,” the White House said in its strategy outline. “Recent IoT vulnerabilities have shown just how easily bad actors can exploit these devices to construct botnets and conduct surveillance.”

As part of CRN’s 2023 Internet of Things 50 list, here’s a look at the tools and vendors leading the way in IoT security.
