Trusted End Node Security (TENS), previously called Lightweight Portable Security (LPS), is a Linux-based live CD with a goal of allowing users to work on a computer without the risk of exposing their credentials and private data to malware, key loggers and other Internet-era ills. It includes a minimal set of applications and utilities, such as the Firefox web browser or an encryption wizard for encrypting and decrypting personal files. The live CD is a product produced by the United States of America's Department of Defence and is part of that organization's Software Protection Initiative.

TENS-Public Deluxe includes the open-source LibreOffice software suite.
