Openbsd is a solid-style Icon from Simple Icons set.

The OpenBSD icon shows a spiky pufferfish with a rounded face, eye, fins, and dense pointed texture. Drawn in the solid style on a 24px grid so its bold silhouette stays recognizable in compact UI. Use it for OpenBSD branding, operating system references, cybersecurity tools, developer resources, and open-source software interfaces. It belongs to Simple Icons free set in the Brand Logos family.
