Local sandboxing for GitHub Copilot now generally available
GitHub Copilot has announced the general availability of local sandboxing, which enables developers to run workflows in a secure environment on their own machines. This feature offers a secure execution boundary, limiting the access of tools and commands initiated by Copilot to the filesystem, network, and credentials as per developer-defined policies. Powered by Microsoft eXecution Container, local sandboxing enhances security across Windows, macOS, and Linux while allowing organizations to enforce strict access controls.
