Summary
In its weekly release published September 10, 2026 (covering the week of September 7), GitHub shipped enterprise-managed sandbox controls for GitHub Copilot in JetBrains IDEs in public preview, letting administrators centrally configure sandbox enablement and govern filesystem, network, proxy, and developer-tool access for Copilot agents.
What changed
GitHub Copilot in JetBrains IDEs gained public-preview enterprise-managed sandbox controls, allowing administrators to centrally configure sandbox behavior and manage filesystem and network access, proxy settings, and developer-tool permissions.
Why it matters
As Copilot agents run and execute code locally, enterprises need to bound what those agents can touch. Central sandbox policy for JetBrains extends Copilot's admin controls beyond VS Code and signals that governance of agent execution is becoming a purchase requirement for regulated engineering organizations.
