Samsung Knox is a security platform designed for mobile devices, particularly Samsung Galaxy devices. It provides real-time, end-to-end protection by securing devices from the chip level up. This means it not only protects software but also hardware, ensuring that sensitive data such as PINs and biometrics are safeguarded against sophisticated attacks.

Samsung Knox employs a multi-layered security approach that includes hardware-based protection through Knox Vault, which acts as a safe for sensitive data. It also features Real-time Kernel Protection (RKP) to prevent unauthorized changes to the device's operating system. Additionally, Knox collaborates with industry leaders like Google and Cisco to enhance security and address potential vulnerabilities proactively.

Real-time protection is crucial because mobile devices are often in use 24/7, making them vulnerable to attacks at any time. Samsung Knox ensures that devices are continuously monitored and protected against threats such as malware and unauthorized access, which can lead to data breaches. This proactive approach helps maintain the integrity of user data and device functionality.
