An IoT gateway serves as the first line of defense in an IoT network. It uses built-in security features like data encryption, firewall protection, and anomaly detection to prevent cyber-attacks. By filtering traffic before it reaches the cloud, gateways help keep critical data safe. Some also use AI to identify unusual behavior and block threats. For industries handling sensitive information, investing in a secure gateway is a smart move toward building a safe IoT ecosystem. Visit: https://www.karikala.in/blog/iot-gateway/
