For a small engineering team, yes. A private Git repository with a control list, policies, exception files and evidence exports can run a real GRC program with review, history and access control built in. It stops scaling when many non-engineers need to collaborate, or when evidence volume outgrows scripts.
What you get for free from Git
- Version history: who changed what, and when.
- Review and approval through pull requests.
- Access control through repository permissions.
- Diffs that an auditor can read.
- Automation through scheduled workflows.
These are the same properties you want from a controlled document and change process.
A minimal layout
grc/
controls/ one Markdown file per control (narrative)
policies/ one Markdown file per policy, with owner and review date
exceptions/ one file per exception, with expiry date
evidence/ dated exports, indexed by control and period
scripts/ evidence collection and checks
CODEOWNERS owners for each folder
What goes in each
| Folder | Content | Check you can add |
|---|---|---|
| controls | Objective, owner, frequency, evidence source | CI fails if a field is missing |
| policies | Text, version, approval date | CI fails if next review date has passed |
| exceptions | Reason, scope, approver, expiry | CI fails if expiry has passed |
| evidence | Exports with run date, hash and query | Script warns if a control has no evidence for its period |
| scripts | Pulls from source control, cloud, identity | Scheduled run and failure alert |
Settings that make it trustworthy
- Protect the main branch, require pull requests and approvals.
- Use CODEOWNERS so each folder needs its owner's review.
- Stop administrator bypass, or record and review it.
- Keep the repository private and limit write access.
- Back it up to a second location.
- Store large or sensitive evidence in a locked-down bucket and keep only an index and hashes in the repo.
Where it stops working
- Non-engineers. Reviewing Markdown in pull requests is awkward for many compliance and HR colleagues. Give them a rendered view or a simple way to comment.
- Volume. Hundreds of evidence files per month need real storage and search.
- Workflow. Tracking approvals across many people and reminders outside engineering can outgrow issues and actions.
- Auditor access. Give read-only access to a defined area, not the whole repository.
When you hit these limits, you can move to a dedicated platform with the structure already in place, since the control list and narratives transfer easily.
Start this week
- Create the repository and the folders.
- Write five control narratives for your highest-risk controls.
- Move your top three policies in with owners and dates.
- Add one evidence script, for access lists.
- Add the CI checks for expired exceptions and stale policies.
Quick check
Will auditors accept a repository as the system of record?
Often yes, if the records are controlled, dated and explained. Ask your auditor early how they prefer to receive them.
What should never go in the repository?
Secrets, customer data and raw sensitive exports. Keep an index and a hash instead.
