# The V8 Sandbox · V8

**[V8](https://daily.dev/sources/v8)** · 10 min read · 2 upvotes · 0 comments

## Summary

The V8 Sandbox is a security mechanism designed to prevent memory corruption in V8 from impacting other memory in the process.

The sandbox isolates V8's heap memory and replaces data types that can access out-of-sandbox memory with sandbox-compatible alternatives.
