VERDICT

Should I use Kicksecure?

A secure by default operating system with the latest security research in place. - kicksecure.com

Depends. Worth adopting for Linux users with a genuine hardening threat model who accept self-support and rough edges. Everyday users and businesses should skip it — a mainstream OS with sensible defaults fits better.

Confidence

Medium. Based on 20+ public sources; Kicksecure is free open-source software, not a paid SaaS, so 'buy' means adopting it.
