Samsung Knox makes mobile security effortless

From secure hardware to real-time protection, and a comprehensive set of advanced security solutions. All you have to do is turn on your phone and go about your day.

Designed and built secure

Samsung hardware is built secure—from the design to manufacturing to the moment we put it in your hands, and for years of use beyond. We seek to deliver security throughout all steps with our own supply chain, built from the chip up.

Open to evolve

We strive to evolve our security solutions on a spirit of openness and partnership, starting with Android‘s proven multi-layered security and adding best-in-class technologies to address the constantly changing threat landscape.

Tools for your business

We also create a comprehensive suite of cloud-based solutions that extend the value of Knox security for businesses even farther. Fully optimized for Samsung Galaxy devices, they put IT admins in control and let people do their work securely and productively.

Hardware backed

Trust begins with hardware

Samsung security architecture has always been backed by advanced hardware solutions—and always will be. We build security into each device from the ground up to safeguard your most precious data.

Knox Vault

Safeguarding your most important credentials

Protect your most precious information— passwords, biometrics, PINs, crypto keys—from tampering, probing, side-channel attacks and fault injection. Knox Vault architecture is CC EAL 4/5+¹ certified, with a dedicated security chip that only you can access.

Warranty Bit

Access only when trusted

When Warranty Bit detects tampering, access to sensitive apps like Samsung Pay, Samsung Pass, and your Android Work Profile will automatically be blocked to prevent misuse. IT can check Warranty Bit remotely using Knox Attestation, and utilize with other management policies.

Secure Boot

Trusted from the boot up

Ensure device security with on-device, OS-independent integrity checks utilizing TrustZone. If the firmware was rooted or there were changes to system components, they can be found when the device boots up.

Secure Supply Chain

Built by Samsung

Samsung is one of the few companies with strong control over the design and manufacture of its own products.² This can ensure end-to-end security across the supply chain and throughout the product lifecycle.

Permission Manager

Protecting personal data privacy

Data protection

Secured from the inside and out
