Android
Android, as a free and open-source mobile operating system, serves as the foundation for CopperheadOS itself. While stock Android may not offer the same out-of-the-box hardening, its open-source nature allows for significant customization and security enhancements for those willing to delve deeper. It's a versatile platform for smartphones and tablets, offering features like ARM support, Google integration, and a Linux-based kernel.
