wolfGuard for Tailscale FIPS-Compliant Tailscale Mesh VPN
wolfGuard for Tailscale is a FIPS-compliant implementation of the Tailscale mesh VPN. Built on wolfGuard and powered by wolfCrypt's FIPS 140-3 validated cryptography, it preserves the simplicity of Tailscale while replacing its standard cryptographic operations with FIPS-certified algorithms across the stack. The result is end-to-end FIPS 140-3-compliant mesh networking for government, defense, and other regulated environments.
