Ferrous Systems is developing an air-gapped environment feature for Ferrocene, its safety-qualified Rust compiler toolchain. The feature allows organizations to use Ferrocene and vetted Rust crates in isolated, internet-disconnected environments. A transfer zone with internet access handles central downloads; once inside the air-gapped environment, files are served via a local server and offline crates instance. The feature offers full control over which toolchain versions and packages are permitted, supports compliance workflows, and is planned for the 26.08 Ferrocene release. A demo is being shown at embedded world 2026.
