Questions, briefly.
What is an AI agent sandbox?
Isolated infrastructure where an AI agent runs code and tools. In kosa8 each agent gets its own microVM with its own kernel, a closed network, and no API keys inside.
How is it different from a container?
A container shares the host's kernel, so one kernel bug can reach every agent on the machine. A microVM has its own kernel and a hardware boundary.
Does it stop prompt injection?
Nothing stops an agent from reading a malicious instruction. kosa8 limits what that instruction can do: no unlisted network, no real keys, approval for risky commands, and a rewind.
Can it run inside our own network?
Yes. The same sandboxes run on kosa8 Cloud, on your own servers or cloud account, or fully air-gapped.
Let your agents work. Keep the keys.
