“A lot of the manufacturing behind IoT devices today feels like the Gold Rush… everyone wants to get there in a hurry,” John Cook, senior director of product management at Symantec, said at the 2018 RSA conference. “You effectively have people staking out a claim in the area without further thought to security.”

What Is IoT Security?

IoT security involves outfitting IoT devices with the latest tools in order to secure the transfer of data, prevent hacking and ensure that privacy standards are maintained. Companies providing IoT security are just as important as the connected devices themselves.

As the Internet of Things expands, threats and potential threats continue to multiply. Fortunately, the market for advanced IoT security is expanding, too, with numerous companies specializing in or at least providing tools to help keep businesses and individuals safe from increasingly sophisticated cyber crime.


What Is IoT Security? 

The reign of smart technology and IoT networks brings increased accessibility and innovation, but it also brings increased cybersecurity concerns. Anything from an Amazon Alexa to a smart refrigerator can be hacked, meaning any IoT devices implemented into your home or business are at risk of cyberattack.

Due to this, companies offering IoT security measures have taken the spotlight.

IoT security involves outfitting IoT devices with the latest tools in order to secure the transfer of data, prevent hacking and ensure that privacy standards are maintained. Ensuring IoT security both protects user personal information and saves costs associated with a breach, making the practice an important initiative.

These 13 companies give a lot of thought to security, be it using IoT to create safer environments or preventing malicious attacks on IoT devices.
