from the moment you turn on the device, iOS can provide you with built-in security. IOS has specially designed low-level hardware and firmware functions to prevent malicious software and viruses. At the same time, it is also designed with high-level OS functions, which helps to ensure security when accessing personal information and corporate data. In order to protect your privacy, apps that get location information from calendars, address books, reminders and photos must first get your permission.

you can set a password lock to prevent unauthorized access to your device, and configure it to allow the device to delete all data after many failed attempts to enter the password. This password will also automatically encrypt and protect your stored emails, and allow third-party apps to encrypt their stored data.

iOS supports encrypted network communication, which can be used by app to protect sensitive information during transmission. If your device is lost or stolen, you can use the "Find My iPhone" function to locate the device on the map and remotely erase all data. Once your iPhone is recovered, you can also restore all the data you backed up last time.
