Set Up GitHub Copilot Enterprise for Your Team

Enterprise adds codebase-wide understanding, security scanning, and policy controls to Copilot.

Prerequisites

• GitHub Enterprise or GitHub Team plan
• Admin access to the organization

Step 1: Enable Copilot in org settings

Go to your GitHub org → Settings → Copilot. Enable Copilot for all members or select specific teams. Set policies: which models are allowed, what Copilot can suggest.

Step 2: Index your repos

In Enterprise, you can index specific repos for codebase-wide understanding. Go to Copilot → Knowledge Bases. Add the repos you want Copilot to understand deeply. Indexing takes time on large repos.

Step 3: Install in VS Code or JetBrains

Developers install the GitHub Copilot extension in their IDE. Sign in with GitHub. Copilot is immediately active. No per-user setup needed beyond authentication.

Step 4: Configure security scanning

Enable Copilot security review in GitHub Actions. Add to your workflow: github/copilot-security@v1. It scans PRs for vulnerabilities and suggests fixes inline.

Step 5: Measure adoption

In org settings → Copilot → Metrics, view: acceptance rate, lines suggested vs accepted, active users. Use this to understand adoption and ROI. Low acceptance rate signals the model needs tuning or developers need training.
