It is recommended to use SDC sandbox and driver layer encryption technology. Sandbox encryption is a container, regardless of software type and file size. Files stored in the computer do not need to be set manually, and it is forbidden to take screenshots, copy document contents and print them, so as to avoid spreading text materials through online forums.

The storage interface is also restricted, and it is forbidden to use U-port serial port and network port to spread files. If you need to send a file, it must be approved before it can be sent.

In this way, even if the external storage interface is not blocked, there is no need to worry about data leakage. After all, the sealing of the interface will have a great impact on your usual work.
