What is the Wall of Sheep?

The Wall of Sheep is an interactive demonstration of what can happen when network users let their guard down. We passively observe the traffic on a network, looking for evidence of users logging into email, web sites, or other network services without the protection of encryption. Those we find get put on the Wall of Sheep as a good-natured reminder that a malicious person could do the same thing we did . . . with far less friendly consequences. More importantly, we strive to educate the "sheep" we catch—and anyone who wants to learn—how to use free, easy-to-use tools to prevent leaks in the future.
