Tencent Open-Sources CubeSandbox: Secure Agent Isolation with Rollback
Key Info
Tencent AI has open-sourced CubeSandbox, a secure VM-based sandbox that isolates each AI agent task in its own kernel, keeps credentials in a vault, and enables snapshot rollback when an agent step goes wrong.
Highlights
- Each task gets its own kernel, so untrusted agent code never touches your host data or credentials.
- Credentials are stored in a vault and injected at the gateway, never inside the sandbox.
- Snapshot rollback gives agents an "undo" button, making recovery the other half of safety alongside isolation.
