The problem
Every CAD file on Fusion 360’s cloud, every scan on Google Drive, every G-code file on Dropbox — that’s not your storage. That’s a rental agreement with a company that can change terms, raise prices, get acquired, or shut down at any time.
Worse: your files are training data. Cloud providers mine usage patterns. AI companies scrape publicly accessible content. Your life’s work is one terms-of-service update away from feeding someone else’s model.
For defense and aerospace contractors, the problem is existential. CUI on a foreign cloud provider is a CMMC violation. The major cloud providers all have data centers overseas and complex subprocessor agreements that make true data sovereignty nearly impossible to prove.
