How to Review Access Controls in a Startup
An access controls review helps you understand whether people, contractors and service accounts have the right level of access — and whether risky permissions are still justified.
Quick Verdict
A startup access controls review should check who has access, what level they have, why they need it, whether it was approved, whether it is still required and whether admin or sensitive access is properly restricted.
Without letting permission gaps scale quietly as the team grows.
For founders, security becomes commercially important when it affects trust, sales, procurement, investor confidence or operational control. The goal is not to build an enterprise security programme too early. The goal is to know what matters now, what can wait and what needs evidence.
The NCSC small organisations guidance focuses on practical areas such as protecting accounts and devices, backups and spotting scams. Cyber Essentials is also described by GOV.UK as a set of standard technical controls designed to protect organisations against common online threats.

Access review checklist
Use this section as a practical founder checklist. It is designed to turn vague security concern into a clearer set of questions, decisions and next steps.
| Review item | What to check | Risk if ignored | Evidence to keep |
|---|---|---|---|
| User access | Active users, roles and business need. | Old or excessive permissions remain. | User export and review notes. |
| Admin access | Who has owner/admin/superuser rights. | Compromise has greater impact. | Admin list and justification. |
| Leavers | Former staff, contractors and dormant accounts. | Ex-employees retain access. | Removal records. |
| Shared accounts | Generic logins and shared passwords. | No accountability or clean removal. | Shared account register or removal plan. |
| Service accounts | Machine identities, API keys and integrations. | Hidden access persists unnoticed. | Owner, purpose and review date. |
How to approach it
Export users from key systems
Start with the systems that hold customer data, financial data, production access or sensitive company information.
Mark admins separately
Admin access needs more scrutiny than standard user access.
Ask managers or system owners to confirm need
Do not rely on IT alone. Business owners should confirm whether access still makes sense.
Remove, reduce or justify access
Every unnecessary permission should be removed, reduced or documented with a reason.
Keep review evidence
Save exports, decisions, removals, exceptions and review dates so you can show the process happened.
Use this when...
- A customer asks how you review access
- You have not reviewed permissions recently
- Leavers and contractors may still have access
- Admin rights are unclear or too broad
Choose your next security step
If you are still unsure where the biggest gap is, start with the quiz. If the issue is already affecting customers, evidence or leadership decisions, book a consultation.
Frequently asked questions
What is an access controls review?
It is a structured review of who has access, what permissions they have, whether access is still needed and whether risky access is controlled.
What systems should startups review first?
Start with email, cloud storage, code repositories, production, finance, CRM, HR and any tool containing customer or sensitive data.
How often should access be reviewed?
High-risk systems should be reviewed more often. At minimum, review access when roles change, people leave, systems change or customer scrutiny increases.
What should I do if access is messy?
Start by documenting current access, removing obvious leavers, restricting admin rights and creating a repeatable review process.
