@Andres_v_Rey Sandboxes are completely isolated from one another, including network. Only the agent using it would have access to it.

If you wish to cut off the internet access for a sandbox, that's configurable and again only the agent using it would have access.

Today, we’re excited to introduce https://t.co/J7xbSEdj6z — the execution layer for the agentic internet.

Run RL agents, computer-use, and untrusted code in secure, isolated sandboxes that scale instantly. Private beta goes live today — we’ll approve waitlist access in batches.
