Trusted End Node Security (TENS)

Prior to the 1.7 release, TENS was known as Lightweight Portable Security (LPS).

The Public Deluxe edition is the same as Public, but with additional software that most people might not need in every session, such as LibreOffice, Adobe Reader, Citrix Workspace, and VMWare Horizon.

If you are unable to download .iso format files, or are getting incomplete downloads, you may wish to try the .zip format instead. Note: the file format contained in the ISO is already compressed, so these ZIP files are not meaningfully smaller (and might even be larger).

Important Restrictions

  • A 650MiB/682MB ("74 minutes") CD-ROM will not hold many of the Deluxe editions. A 700MiB ("80 minutes") or larger CD-ROM must be used along with a writer that properly detects such. For the most recent Deluxe editions, we recommend at least a DVD±R disc.
  • Beginning with 3.0, TENS is a 64-bit-only OS and thus is incompatible with 32-bit hardware. If you are using 32-bit hardware, you must use 1.7.6 or earlier.

Government Edition Requirements

  • Review the description of EW-Govt and check that you fulfill the requirements. Note that EW-Unified may also qualify for use, depending on your circumstances, and is easier to obtain.
  • For the automated download, a DoD CAC and a web browser configured to use it are required. If you do not have both of those but fulfill the personnel requirements, fill out the request form below, keeping the caveats in mind.

Bootable Media (BootMe)

All editions of BootMe are custom built, and typically arrangements for retrieval/delivery are made per-organization. They are also FOUO, and certain parts are not Distribution A, so they are not presently available from the public-facing parts of this site. Some organizations have made their BootMe images available for download via the DoD Portal; this requires a CAC and a browser configured to use it.
