LPS and its successor TENS was developed and publicly distributed by the United States Department of Defense’s Air Force Research Laboratory[3] The live CD is designed to serve as a secure end node.

[6][7][8] LPS turns an untrusted system (such as a home computer) into a trusted network client.

As of September 2011 (version 1.2.5), the LPS public distribution includes a smart card-enabled Firefox browser supporting DoD's CAC and Personal Identity Verification (PIV) cards, a PDF and text viewer, Java, a file browser, remote desktop software (Citrix, Microsoft or VMware View), an SSH client, the public edition of Encryption Wizard and the ability to use USB flash drives.

[12] UEFI Secure Boot is used to protect the operating system installed on the computer's hard drive.

[14] LPS came with Encryption Wizard (EW), a simple, strong file and folder encryptor for protection of sensitive but unclassified information (FOUO, Privacy Act, CUI, etc.).

Without installation or elevated privileges, EW ran on Windows, Mac, Linux, Solaris, and other computers that support the Java software platform.

With a simple drag and drop interface, EW offered 128-bit and 256-bit AES encryption, SHA-256 hashing, RSA signatures, searchable metadata, archives, compression, secure deleting, and PKI/CAC/PIV support.

The official web site, offering the public versions of TENS, was hosted on Department of Defense servers.
