Defense-grade security available to everyone

At Samsung, we believe that the only person in control of your data should be you.

Because your data holds your secrets, every Samsung device is built to protect it. With defense-grade data security built from the chip up, Samsung Knox secures what matters most. Giving you complete control over your personal information privacy, so you’re free to keep doing what you do, whatever you want to do it on.

Protect your identity

Even if you lose your phone, strong password policies—including biometric authentication—help ensure that your data stays safe. Samsung face recognition technology turns your facial features into a password. And the in-screen fingerprint sensor keeps other’s hands off your data using ultrasonic or optical technology. With Samsung Pass, you become your password, so accessing your devices is not only easier, but more secure.

*Fingerprint Recognition and Face Recognition not available on all devices.

Shield your personal data

Built-in security measures on each Samsung device ensure your data is protected from the start. For extra protection, we’ve added Secure Folder to every handset. Complete with secured apps, storage, and galleries, Secure Folder is a separate space on your device to store your most important, or most secret files with absolute confidence. And because your health is your business, we’ve bundled it all up in your device, safe from the hands of others. Track your activity, nutrition, and sleep with insights based on your progress.

But even things that aren’t built in need security, so we’ve included the ability to encrypt your SD cards. Meaning whether or not it’s in use on your phone, the files and information on it stay safeguarded.

Secure your connections

Keep your incoming calls and network traffic private even in a crowded space on an unprotected network. We’ve created Secure Wi-Fi allowing you to browse safely on public wireless connections without fear of security breaches. All outgoing data will be encrypted to protect you from hackers and malware.

*Secure Wi-Fi feature availability may vary depending on country, carrier, or network environment and not be supported on all Samsung mobile devices. Provided for free under 250MB per month.
