Secure Disk enables you to encrypt the content of local or removable USB/Flash disks. It uses 256-bit AES encryption at the physical sector level to protect your data from unauthorized access. The software works at the operating system level and constantly encrypts/decrypts your data as it is accessed, so even if the drive is removed, your data remains encrypted an inaccessible without the proper passwords. While working on the computer where Secure Disk is installed, you can access the encrypted drive(s) and files just as you would on any other drive, as long as you are logged in from the Secure Disk control panel.
Secure Disk provides the ultimate security standard for encryption at the physical sector level. Based on the most secure technology, AES256, this product is an excellent data security tool.
Another outstanding feature is the support of flash media and USB hard disk drives, so that no one will be able to access your data if you lose it.
AES256 used for data encoding is considered to be one of the most efficient and stable algorithms. This algorithm was ratified by NIST(National Institute of Standards and Technology) and favorably distinguishes our program from other tools. The algorithm was also approved by FIPS(Federal Information Processing Standards), therefore, this product is accepted by US governmental organizations for data security purposes.
The primary function of Secure Disk is hard drive and flash memory encryption. Pre-boot authentication and encryption of the whole drive, including the system files, gives this program superiority over similar products.
The software has a user-friendly interface and doesn't require constant attention. No additional skills are required to use this software.
It takes approximately one minute to create a key, and about 20-40 minutes to encrypt the data.
Secure Disk works as a driver without affecting processing speed. When the software or OS reads the data into RAM, Secure Disk reads and decrypts that data, and than encrypts it when recording on a disk. Data is constantly encrypted and therefore inaccessible even if the disk is removed.
