[ ABOUT COYOTE LINUX ]
History
Coyote Linux has been providing firewall and router solutions since 2000. Originally designed to fit on a single floppy disk, it enabled organizations to repurpose old hardware as dedicated network security appliances.
Coyote Linux 4 represents a complete rewrite for modern hardware and security requirements, built on Alpine Linux with an immutable firmware architecture.
Design Philosophy
- > Immutable firmware with safe rollback capability
- > Configuration stored separately from system image
- > Minimal attack surface through reduced footprint
- > Appliance-style deployment and upgrades
- > Ed25519 firmware signature verification
