Who can see what
in your business?

A login is not enough. Here is a plain-English guide to making sure each person sees only what they should, for medical practices, law firms, franchises and financial firms.

Who should be able to see what in your business system? Each person should see only what their job needs, and every change should be written down. A login on its own does not do that. A login only proves who someone is. It says nothing about what they are allowed to open once they are inside.

// Chapter 01 — The problem

A login is a front door, not a set of locked rooms

Most business systems start small. A few staff, one login each, and everyone trusts everyone. Then the business grows. A second branch opens. A bookkeeper joins. A new client needs a portal. Nobody stops to ask what each of those people can now see.

Usually the answer is: more than they should. Nobody means any harm. It is simply that access was handed out one request at a time, and nobody went back to tidy it up. The risk is not a villain. It is an ordinary mistake, such as a franchisee opening the wrong branch's numbers, or a former employee who still has a working password.

A login proves who you are. It does not decide what you are allowed to see.
// Chapter 02 — What good looks like

Four simple parts

Proper access control is not complicated to understand. Think of an office building.

01Door
The login: proves who you are
Everyone gets their own login. Nobody shares one.
02Rooms
The permissions: decide what you can open
Each person can only open the rooms their job needs. Reception, billing, practitioners and managers each see something different.
03Logbook
The record: who opened or changed what, and when
If something goes wrong, or someone simply asks, you can look it up instead of guessing.
04Off switch
The off switch: remove someone's access in one step
When a person leaves, or a partner relationship ends, their access ends the same day.
// Chapter 03 — Who this is for

Any business that holds other people's information

Medical practices hold patient records. Reception, practitioners and billing should each see what they need and nothing more. Law firms hold confidential client files, and each matter should only be open to the people working on it. Franchise networks should let each franchisee see their own branch while head office sees the whole picture. Financial firms and bookkeepers hold one client's numbers next to another's, and those should never mix.

The details change from business to business. The question is always the same: who can see what, and can you prove it?

// A login on its own
Hope nothing goes wrong
  • Anyone logged in may see too much
  • The rules live in people's heads
  • Nobody can say who looked at what
  • People who left may still have access
// Proper boundaries
Know who can see what
  • Each person sees only their own part
  • The rules are built into the system
  • Every change is recorded
  • Access is removed in one step
// Chapter 04 — How it is built

Built in from the start, not added later

The safest way to do this is to build it into the system from day one. That means the system itself refuses to show information to the wrong person, so it does not depend on someone remembering to switch a setting on. It also means the rules are written down in one place, so you can see them and change them.

Forge Vertical builds these systems on established cloud infrastructure, including Google Cloud, Firebase and Cloudflare. Our own marketplace, TripSpace Global, runs on this approach. Partners are individually approved, each sees only their own dashboard, and payment details are kept in a locked, separate place.

A note on the law. South Africa's Protection of Personal Information Act (POPIA) expects organisations to take reasonable, appropriate steps to protect the personal information they hold. Controlling who can see what is one of the clearest ways to show you have done that. It is not a guarantee, and it is not legal advice, so speak to your attorney about what applies to your business.

You do not have to work it out alone

You know your business. You do not need to know the technical side. Tell us how your business runs and who needs to see what, and we will show you, in plain language, what the access should look like and what it would take to build. You decide once you have seen it. If it is not right for you, you will still know what good looks like.

// Questions answered

What does 'who can see what' mean for a business?

It means each person who logs in can only see the information their job needs. A franchisee sees their own branch, a receptionist does not see billing, and a client sees only their own documents. Every change is recorded, so you can see who did what and when.

Is a password enough to protect business data?

No. A password only proves who someone is. It does not decide what they can see once they are inside, and it does not record what they do. You also need permissions for each person and a record of activity.

Is this relevant for medical practices and law firms?

Yes. Both hold highly sensitive records. Each person should see only what their role requires, and there should be a record of who opened what. Check with your professional body about any extra rules that apply to you.

Does this help with POPIA?

It helps. POPIA expects organisations to take reasonable steps to protect personal information, and controlling and recording access is one of those steps. It is not a guarantee of compliance, and you should ask your attorney what applies to your business.

How do I get started?

Get in touch by WhatsApp, email or the free quote form. Tell us how your business runs and who needs to see what. We will show you in plain language what the access should look like and what it would take to build, and you decide after that.
