Ferrocene for air-gapped environments

Ferrocene and vetted crates going offline

See it in action at embedded world, Hall 4, Booth 4-402

We at Ferrous Systems are excited to share insights into a new feature in development, designed to enable Ferrocene and Rust crates in high-risk environments requiring maximum security, strong protection against cyberattacks and strict control over infrastructure, data, and compliance workflows.

At embedded world 2026, Ferrous Systems is presenting a demo that shows how the safety-managed Rust compiler toolchain, as well as selected crates, can be accessed offline, thus enabling teams to build any Rust application in isolated environments.

Running the demo installs the Ferrocene toolchain and its manager as well as selected crates. It sets up an example Rust project, builds and runs it—all while being offline.

Going forward, organizations will be able to decide on what they want to grant access to: multiple versions of the Ferrocene toolchain, selected packages and vetted crates. In a transfer zone with internet access, this preselection gets downloaded centrally. When in the air-gapped environment, the files are made available via a server and an offline crates instance, which the users can access to download whatever they need for their respective Rust projects.

1.1 Advantages

• offline availability
• central download
• vetted crates
• full control over what gets passed into air-gapped environments
• compliant with processes for provisioning air-gapped environments
• ease of use
• full functionality remains

Ferrocene for air-gapped environments and the air-gapped crates integration are planned to be included in the 26.08 Ferrocene release.
