VERDICT

Should I use secureblue?

A security-focused desktop and server Linux operating system. - secureblue.dev

Depends. It's free, so the only cost is migration time — worth it for Linux-comfortable users with a real privacy or security threat model. Skip it if you need vendor support, easy gaming, or a zero-tinker desktop.

Confidence

Medium. Based on 20+ public sources. Medicare 'SecureBlue' (Blue Cross MN) results excluded — unrelated product.
