The icon will represent a header text saying that by using our services you are fully anonymous so I would imagine a server and a user with a connection between them which is being anonymized by the server. Think of a firewall but stick very close to what heroku has there because my page design is based on very related colors (dark design with mint and white colors). I will need a total of 3 icons so maybe the winner will work with me on the other 2 icons.
I want the same colors as in the example I uploaded. Works well with my design bg.
