The amount of information being transmitted from things continues to rise. Much of this data originates outside of the enterprise. The scale of security risks in the Internet of Things (IoT) era is therefore much greater than in the pre-IoT environment, and the "attack surface" is much larger. Most sensor-based things have minimal computing resources, and the opportunities for antivirus, encryption and other forms of protection within things are more restricted. Therefore, IoT security products with a variety of capabilities emerged to help dispel some of these challenges.
