Securing the Engineering Sandbox in Air-Gapped Networks

Why Cloud Software Fails the Engineering IP Test

Engineering IP is the lifeblood of high-tech manufacturing companies. Standard SaaS offerings rely on uploading raw STEP, IGES, or SOLIDWORKS files to third-party servers. For companies working on aerospace components or proprietary automotive drivetrains, this is a non-starter.

The Architecture of an Air-Gapped Sandbox

Building a secure sandbox requires software that can execute entirely on-premises or within a client's private cloud. Digiladder's offline-first architecture uses a three-pillar security model:

1. Local Execution: Code is compiled to WASM/JS, executing inside the user's local browser context.
2. Local Storage: Temporary session files and analytical logs are saved to an encrypted local SQLite database.
3. Signed Licensing: License verification uses asymmetric cryptography certificates validated locally, requiring zero external server pings.

AS9100 and ISO 27001 Readiness

By keeping all files local, manufacturing organizations can easily meet the strict compliance requirements of aerospace (AS9100) and defense (ITAR). There are no external endpoints to audit, no firewall exceptions to configure, and no risk of data breach.
