10 Things to Put in Your Startup Security Evidence Folder
Security evidence becomes stressful when it is scattered. A customer asks a question, and the team searches email threads, Slack messages, screenshots and old folders.
An evidence folder gives founders one place to collect the documents that support due diligence, readiness reviews and customer conversations.
A startup security evidence folder should hold the proof behind your security answers: policies, access reviews, supplier records, risk register, incident process, backup records, training evidence, system list, data summary and customer questionnaire responses.
Evidence folder sections
- Policies: check whether this is owned, evidenced and reviewed.
- Access: check whether this is owned, evidenced and reviewed.
- Suppliers: check whether this is owned, evidenced and reviewed.
- Risk register: check whether this is owned, evidenced and reviewed.
- Incident response: check whether this is owned, evidenced and reviewed.
10 Things to Put in Your Startup Security Evidence Folder
Use this list as a practical review prompt. Each item is either a visible issue, a gap to close, or a security activity founders should make easier to explain before customer, investor or audit pressure arrives.
1. Policies
Store approved policy documents and note who owns each one. Policies should reflect how the team actually works.
What to do: Keep version dates and owners visible.
2. Access reviews
Include admin lists, access review outputs, leaver checklists and approval evidence.
What to do: Create dated folders for each review.
3. Supplier security
Store supplier register, review notes, contracts or due diligence summaries for vendors handling data or critical services.
What to do: Record supplier owners.
4. Risk register
Keep the current security risk register and any related risk review notes.
What to do: Update after major changes.
5. Incident response
Store escalation contacts, incident process, tabletop notes and any incident records.
What to do: Make the process easy to find.
6. Backups and recovery
Include backup scope, frequency, owners and restore test evidence.
What to do: Record the last restore test date.
7. Training and awareness
Store training completion records, awareness schedule and key guidance shared with staff.
What to do: Track who completed what.
8. System and asset list
Maintain a list of critical systems, owners and what data they hold or support.
What to do: Focus on critical systems first.
9. Data handling summary
Record where customer data is stored, who can access it and key handling rules.
What to do: Keep it practical and current.
10. Customer questionnaire responses
Save completed responses so future answers stay consistent and improve over time.
What to do: Reuse carefully and update before sending.
How to Turn These Issues Into Action
The fastest way to make this useful is to turn each issue into an owner, an action, a review date and a simple piece of evidence.
| Issue / Area | Action to Take | Evidence to Keep |
|---|---|---|
| Policies | Keep version dates and owners visible. | Owner, date, decision and supporting record |
| Access reviews | Create dated folders for each review. | Owner, date, decision and supporting record |
| Supplier security | Record supplier owners. | Owner, date, decision and supporting record |
| Risk register | Update after major changes. | Owner, date, decision and supporting record |
| Incident response | Make the process easy to find. | Owner, date, decision and supporting record |
| Backups and recovery | Record the last restore test date. | Owner, date, decision and supporting record |

What is a security evidence folder?
It is a central place to store documents, records and exports that support your security claims.
Should a startup create an evidence folder before an audit?
Yes. Creating it early reduces pressure when customers, investors or auditors ask questions.
What format should the evidence folder use?
A simple shared folder or workspace is enough if it is organised, access-controlled and owned.
Who should maintain the evidence folder?
Assign one owner, but collect inputs from system owners, operations, engineering and leadership.
