Hardware Security
Secure software requires a foundation of security built into hardware. That’s why Apple devices—running iOS, iPadOS, macOS, tvOS, or watchOS—have security capabilities designed into silicon.

System Security
Building on the unique capabilities of Apple hardware, system security is designed to maximize the security of the operating systems on Apple devices without compromising usability. System security encompasses the boot-up process, software updates, and the ongoing operation of the OS.

Encryption and Data Protection
Apple devices have encryption features to safeguard user data and enable remote wipe in the case of device theft or loss.

App Security
Apple provides layers of protection to ensure that apps are free of known malware and haven’t been tampered with. Additional protections enforce that access from apps to user data is carefully mediated.

Services Security
Apple has built a robust set of services to help users get even more utility and productivity out of their devices. These services include Apple ID, iCloud, Sign in with Apple, Apple Pay, iMessage, FaceTime, and Find My.
