On-Demand: Agent Substrate 101: Not All Sandboxes Are the Same

Agents execute code, call tools, access sensitive systems, and act on our behalf. So yes—you need isolation. But “just put it in a sandbox” leaves a lot unanswered.

In 30 minutes, we’ll break down what a sandbox should actually give you, where different approaches trade off security, performance, and efficiency, and why isolation becomes an infrastructure decision once agents move into production.

You’ll leave knowing:

• What you actually need to isolate—and why
• What to look for in an agent sandbox
• Where security, startup time, density, and cost collide
• How the right isolation model fits into an Agent Substrate

The big question: How do you give every agent a safe place to work without building an expensive neighborhood of empty sandboxes?
