IoT security is critical due to the rapid growth in connected devices and rising cyber threats.
Leading companies like Armis and Fortinet use AI and automation to protect smart systems.
Both global firms and niche players are shaping the future of IoT security with innovation.
The Internet of Things (IoT) sector is expanding rapidly. Smart devices like cameras, sensors, home assistants, and industrial machines are interconnected to offer streamlined services. This growth has made life easier, but it has also created serious security risks. Hackers are increasingly targeting these devices to access your personal information.
A recent global cyber operation showed that more than 360,000 routers and IoT devices were infected, and this botnet spread across 163 countries. Such incidents have pushed companies to focus strongly on IoT security. Many firms are using artificial intelligence and smart monitoring systems to protect devices.
Below are the top 10 IoT security companies leading this space:
Armis is one of the most important IoT security companies today. It helps businesses find and monitor all connected devices without installing software on each one. Its system can detect threats in real time and stop attacks quickly. Armis became even more popular after a major $7.75 billion acquisition deal by ServiceNow, showing its high value in the market.
Palo Alto Networks is a global cybersecurity leader with strong IoT protection tools. Its platform uses artificial intelligence to study device behavior and detect unusual activity. The company supports more than 80,000 customers worldwide. Its solutions are widely used in healthcare, especially for protecting medical devices.
Fortinet provides a complete security system that protects networks and IoT devices together. Its technology uses automation and AI to block threats and control device access. It is especially useful for large organizations where many devices are connected at once.
