This poster illustrates the importance of encrypting email. It is part of a series of posters designed to garner awareness for U.S. European Command's Operation Security program. Eric Steen, a visual information specialist with the Training Support Center, Stuttgart, designed the poster the week of Feb. 8, 2016.

Transmission on private sector communications channels is prohibited.  Non-DOD-controlled electronic messaging services ARE NOT AUTHORIZED to process non-public DOD information, regardless of the service’s perceived appearance of security (e.g. “private” social media accounts or groups, “protected” or “encrypted” messaging applications, such as WhatsApp, Signal, Line, etc.).
