AI agents are getting powerful enough to need their own security layer NVIDIA just open-sourced OpenShell It lets you sandbox agents, control what they can access and monitor what they’re doing Watching an agent work inside these boundaries is pretty wild

we're going to need way more of this as agents get more autonomous

the more capable agents get, the more important this becomes

The network side is where it shows most: with an egress allowlist, a confused agent simply cannot reach anywhere it should not.

the idea of being able to quarantine an agent is wild

giving agents access to computers without proper isolation sounds terrifying

Agents need permissions and boundaries, not just better reasoning.

this is probably one of the least talked about problems with agents

autonomous agents + no restrictions is a scary combination

imagine an agent running for hours without anyone watching it

AI agents needing security layers is honestly a pretty big shift

agent security is about to become its own entire industry

where do the API keys live in this setup? if they're inside the sandbox, a prompt-injected agent can still just read them

sandboxing agents is going to become standard

this is going to matter a lot more sooner than people think

sandboxing might be one of the most important pieces of agent infrastructure

I still keep anything irreversible out of the agent completely, sending and paying go through plain if/then

agents need a security layer, ship them without one first

Sandbox demos look fine until the policy is prompt-only. Tip: put the deny list in the runtime that wraps the process, and make a restart restore the same policy from disk - otherwise a crash is an escape hatch.
