Alfa Corporation provides file encryption and file protection products as well as custom programming and consulting services in file system development for Windows platforms. We specialize in file system filter driver development, such as file audit, security and privacy.
Our products provide programmers with:
- NEW: Device Blocking driver is in the works! Alfa Device Block will provide fine tuned access control for all system devices.
- On the fly file encryption (OTFE). Alfa Transparent File Encryptor provides strong security for file data. It works on a per-file basis and does not use in-file headers, but headers in ADS streams. No decryption data is recorded or written to the disk (only files, in encrypted form). Data is decrypted only when in memory, and never on the disk. The process is seamless to both users and applications.
- File system activity monitoring down to the finest details. Alfa File Monitor is used in software with purposes ranging from disk cataloging to complex document indexing systems.
- File protection and security on any file system and platform and extend that of the NTFS and Windows NT/2000/XP/2003/Vista/2008/7 platform. Alfa File Protector not only secures files, but also truly hides them. This file protection component is used in many (DRM) Digital Rights Management solutions, desktop/laptop/enterprise file security and even internal application data storage security.
