1 - The logo
Since it would be a security company, the client's idea for the logo was to incorporate the concept of Gray Hat (Hacker = it means a hacker that isn't good nor bad, but won't use corporate information for personal gain).
He wanted a gray hat in his logo. So, following his idea, I had the idea of incorporating a hacker with gray hat into the logo in a minimalistic way. Since the Y reminded me a way to represent a person's body, I created the hat and eyes and added them on top of it to create the perception of a hacker there, "hiding".
