I'm very skeptical about the platform and don't have the time to devote to reading the codebase or having conversations as I would like. The TL;DR is that the syscall interception technique seems expensive and I wonder if you will write all sorts of logic bugs in the sentry broker. It seems like you folks care about security, and have some good ideas, but if you really care about hostile multi-tenant containers, why not stick the container in a VM and call it a day?
