The TENS program office has received notification of potential funding cuts from our main funding source, Defense Information Systems Agency (DISA).

Thus, all efforts that fall under the TENS program are in danger of being discontinued. If your agency is interested in continuing these technologies and collaborating with us on funding opportunities, please contact us.

Trusted End Node Security (TENS) technology is developed and managed by the Air Force Research Laboratory (AFRL) Information Directorate. This program began as the Anti-Tamper Software Protection Initiative in 2001 with its flagship products Lightweight Portable Security and Encryption Wizard. The TENS program office offers products that provide network security from the end node perspective while providing user capabilities of remote access, secure web browsing, and file/folder encryption, in addition to other initiatives. The core products sustained by the TENS program are TENS-Public, TENS-Professional, Bootable Media, and various editions of Encryption Wizard. These products are intended to be used by the U.S. Department of Defense and the rest of the Federal government, while also providing Public versions of the software to the open source community, when possible. The Public versions are available for download on our website and are not customized. AFRL has a strong legacy of providing secure end node technology, with a supported user base in the hundreds of thousands.
