USB disk and removable storage devices are very useful when we need to transfer data among different computers. But how to provide better protection to data inside? Of course is to encrypt them with password! Here we will go through about it!

Threats of Data Leak When Transferring Data

When we need to transfer data among different computers, we prefers to make it with removable storage devices like USB flash drive. When considering the data security in office, such behavior is kind of risky because the USB flash drive could be stolen or data inside could be copied without authorization.
If you want to prevent employees from coping data with removable storage devices like USB flash drive, please try the latest software – Renee USB Block which can disable USB ports and provide white-list function which allows users to use the trusted removable storage devices.
Although we could find different encrypted flash drive which can prevent data leak in a better way, it’s so expensive that many users are hesitate to purchase it. Besides, its capacity is limited and can not provide enough protection to files with large size. If you want to provide overall protection to data in removable storage devices, Renee File Protector could be a good choice for you. Encrypt function inside can help you password protect any folder regardless its size before transfer. After saving the encrypted data to target computer, you can decrypt the data. Whole encrypt process is adopted with the advanced algorithm which can not be decrypted with brute-force methods at present. The encrypt and decrypt processes are 100% safe and easy to go.
