Signal Boost

With massive amounts of the federal workforce moving to telework, NSA released a guide for choosing collaboration services for telework purposes. Rather than evaluate popular platforms like Zoom, WebEx, Microsoft Teams, and others based on their features and functionalities, NSA has assessed the tools based on their security and privacy practices. The full report is available here. See the table below for an overview of the some of the telework tools ESS relies on.

Legend: Y = Yes, N = No; (a) text chat, (b) voice conferencing, (c) video conferencing, (d) file sharing, (e) screen sharing.

Highlighted in this table is Signal, a messaging app for Android, iOS, Windows, MacOS, and Debian based Linux distros. If you’re looking for privacy and security in your personal communications, Signal is the application for you. While Signal wasn’t the first end-to-end encrypted messaging application, it claims the title as the most secure while providing first-class user experience and features. The cryptographic algorithm commonly known as the Signal Protocol has been vetted by several independent organizations and security researchers, is completely open source, and has been adopted in other messaging platforms such as WhatsApp, Facebook Messenger, and Skype.
