31## Native sandbox

32 

33The Codex app on Windows supports a native [Windows sandbox](https://developers.openai.com/codex/windows#windows-sandbox) when the agent runs in PowerShell, and uses Linux sandboxing when you run the agent in [Windows Subsystem for Linux (WSL)](#windows-subsystem-for-linux-wsl). To apply sandbox protections in either mode, set sandbox permissions to **Default permissions** in the Composer before sending messages to Codex.

34 

35Running Codex in full access mode means Codex is not limited to your project

36 directory and might perform unintentional destructive actions that can lead to

37 data loss. Keep sandbox boundaries in place and use [rules](https://developers.openai.com/codex/rules) for

38 targeted exceptions, or set your [approval policy to

39 never](https://developers.openai.com/codex/agent-approvals-security#run-without-approval-prompts) to have

40 Codex attempt to solve problems without asking for escalated permissions,

41 based on your [approval and security setup](https://developers.openai.com/codex/agent-approvals-security).
