The cloud industry spent a decade convincing us to trust the operator. Then came confidential computing, which asked us to trust the hardware. Caution, a Y Combinator backed startup, is making a bolder argument: don't trust either—verify the entire software stack yourself, down to the compiler. Caution is a hosting platform for "software you can't afford to have hacked." It deploys workloads to secure enclaves in minutes and provides cryptographic proof of exactly what code is running. The pitch isn't just isolation; it's verifiability. In a world where supply chain attacks and insider threats are constant headlines, Caution's thesis is that the only reliable foundation is one you can check yourself.
