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 always need, like LibreOffice and Adobe Reader.

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).

Beginning with the next major release, TENS will be a 64-bit-only OS and thus will be incompatible with 32-bit hardware.
