Driverware provides I/O control at the driver level for more reliable security than application level control. It limits the use of software and devices and provides real-time encryption and decryption for storage devices, optical media and networks using the AES-256, Blowfish (56-bit) or other encryption format. Driverware not only prevents security breaches caused by user mistakes, but also provides effective control system security, insider threat detection, targeted threat protection and ransomware prevention.
