BSD of course

🚀 OpenBSD: Security by default, no sugar‑coating needed.

🔐 Built‑in PF firewall, W^X memory protection, and the legendary pledge()/unveil() sandbox.

🛡️ LibreSSL & OpenSSH were born here—your data stays locked tighter than a vault.

💡 BSD’s permissive license lets you remix, sell, or ship closed‑source products without legal headaches.

Rock‑solid stability (servers that run for years without reboot).

Clean, readable code—perfect for learning OS internals.

A community that tells it like it is, no fluff.

👉 Ready to experiment? Spin up an OpenBSD VM today and see security the way it was meant to be: default‑on.
