# Vercel：无网络边界的沙箱只是半个沙箱

Vercel 博客发文指出，安全运行不受信任的代码，不仅需要将其与主机隔离，还必须控制代码能访问的网络资源。随着 AI 智能体能够读取文件、执行命令、安装包和生成程序，这一限制愈发重要。微虚拟机可以防止代码访问主机，但若没有网络边界，恶意代码仍可能横向移动或外泄数据。文章强调，完整的沙箱方案必须同时包含计算隔离和网络隔离。

## English Version

**Vercel: A Sandbox Without Network Boundary Is Only Half a Sandbox**

A blog post from Vercel argues that safely running untrusted code requires more than host isolation—you also need to control network access. As AI agents gain abilities to read files, execute commands, install packages, and generate programs, network boundaries become critical. A microVM prevents host access, but without network restrictions, malicious code could still move laterally or exfiltrate data. The post emphasizes that a complete sandbox must include both compute and network isolation.
