Samsung Knox is a built-in, hardware-backed security platform available on Samsung mobile devices. It’s designed for organizations that need to protect sensitive data that employees access on the go — whether that’s corporate files, healthcare records, or government information.

Instead of relying only on software, Knox is integrated from the chip level up. That means protection starts the moment the device is powered on and continues as the operating system and apps load. Because Samsung controls the full supply chain — from device design through manufacturing — Knox can help businesses trust that both work and personal data on the device are protected against many common mobile threats.

Knox uses multiple layers of security that work together, starting at the hardware level and extending through software:

• Hardware Root of Trust: This is the foundation of the platform. It provides a trusted starting point for the device, enabling a series of stringent integrity checks every time the device boots. If something looks tampered with, the system can detect it early.
• Real-time Kernel Protection (RKP): Samsung’s patented RKP continuously monitors the core of the operating system (the kernel) in a separate, isolated execution environment. This helps detect and block attempts to compromise the OS while the device is in use.
• Sensitive Data Protection: Data can be marked as “sensitive,” which means it cannot be decrypted while the device is locked. Even if someone gets physical access to the phone, this adds another barrier to reading critical information.
• Enhanced work/personal separation: Knox builds on the Android Enterprise app container to improve separation between work and personal data. This helps IT teams protect business information without taking over an employee’s entire device.

Together, these layers help organizations rethink how they secure mobile access to important data, from the chip all the way up to the apps employees use every day.

Knox is designed to support a “one device for everything” approach while still protecting business information:

• Work/personal data separation: Knox builds on the Android Enterprise container model and strengthens it. Work apps and data live in a managed, secured space, while personal apps and content stay separate.
• IT control over work data only: Corporate policies, such as encryption, app controls, or remote wipe, can be applied to the work container without affecting an employee’s personal photos, messages, or apps.
• Consistent user experience: Employees can move between work and personal profiles on the same device, reducing the need to carry multiple phones while still keeping corporate, healthcare, or government data under tighter control.

This approach helps organizations reimagine mobile security so they can support flexible, mobile work without giving up control over sensitive business data.
