Problems solved by technology

However, while enjoying the convenience brought by the use of USB storage devices, at the same time, due to the lack of security control and auxiliary management tools, it also brings the risk of possible data leakage

For example, in the internal network of an enterprise or department, employees can use USB storage devices to take the internal data of the company or department out of the workplace at will, and the USB storage devices used on the internal network may also be lost or stolen. leak

Moreover, there are millions of USB storage devices on the market today, and all kinds of internal confidential data have been flowing in these USB storage devices-while facing the risk of loss or theft, the loss of sensitive corporate data leads to The potential loss is increasing exponentially every day
