FESF for Linux

Enterprise Grade Transparent Data Encryption is Coming to Linux

OSR’s popular per-file transparent encryption Solution Framework for Windows will be coming to Linux in 2018.

OSR’s File Encryption Solution Framework (FESF) for Windows makes the development of transparent, on-access, per-file encryption products easy.  The keys to the Framework’s success have been its robustness, the flexible ways that policy can be determined, and the fact that  policy determination is done by FESF-based products entirely in user-mode.  The time to market advantages of using FESF have been proven by multiple commercial products that have been built to date.

Now, OSR is bringing that same cutting-edge robustness, flexibility, and time to market advantage to the Linux platform.

Designed from the ground-up as a native kernel-mode Linux file system, the FESF for Linux Solution will feature compatibility of encrypted files between platforms.  True to the spirit of the original FESF implementation on Windows, the Linux implementation will support flexible policy determination in user-mode by FESF-based products.

OSR is working with a limited number of partners in an “Early Access Program” for FESF for Linux.  These partners get access to periodic builds throughout the development process, and will have the opportunity to provide feedback that can influence the direction of the product.

Yes… we’re very excited about this!

September 2017:

While we have a long way to go yet, we’ve completed some basic prototyping. We have basic on-access transparent encryption and decryption working, with Windows FESF compatibility.  Here’s a very brief (about 3 minute) demo:
