What is IoT Security Software?

IoT (Internet of Things) security software is designed to protect connected devices and networks from cyber threats, ensuring the confidentiality, integrity, and availability of data transmitted between IoT devices. These tools monitor and secure devices, applications, and networks that are part of the IoT ecosystem, which includes sensors, actuators, smart appliances, wearables, and industrial equipment. IoT security software includes features such as threat detection, data encryption, access control, device authentication, and vulnerability management to mitigate risks from cyberattacks, unauthorized access, and data breaches. It is essential for industries like healthcare, manufacturing, transportation, and smart cities, where the IoT devices are widely used and often contain sensitive or critical data.
