IoT device management is the ability to remotely access, diagnose and manage the functionality of your deployed IoT devices. Regardless of their number or location, you will need to check on those devices and periodically update their capabilities and intelligence with firmware updates, or download security patches to make sure they are up-to-date, secure and in compliance.The key factors that explain why this capability is critical are:

• The size of your network
• Whether the devices are physically accessible
• How widely dispersed your devices aregeographically?
