Security is a top priority for many smartphone users — especially those who store sensitive data, use banking or business apps, or share devices with family members.

What Is Samsung Knox?
Samsung Knox is a multi-layered security framework built into Samsung devices. It combines hardware and software protections to secure data at rest, in transit, and during use.
