The stunnel program has been designed to provide security in network traffic. It creates a kind of tunnel, a layer that guarantees confidentiality and integrity of connections. It has its position and recognition in the world. The program’s sign was created earlier than the full logotype.

The client expected a project associated with the tunnel and a good 16 x 16 pixels (0.56 x 0.56 cm) square. It’s really a small space to exist with a clear message and interesting aesthetics. Managed to. The logo is intuitively associated with the description of the program and looks good in every size. Colors (green, blue, red) inform you about readiness, job and installation errors.
