A South African software company
Software for the people.
Sentrio Systems builds practical tools for companies whose people work on site and on shift, often far from a desk and a good signal. We start with the industry we know best: security guarding.

What we do
We turn paper, WhatsApp and spreadsheets into one working day
Most frontline companies run on a mix of paper books, message groups and a spreadsheet nobody trusts. We replace that with software their people can use on the first day.
We sit with the people who do the work
Our first product was shaped at the desk of a working guarding company. What they could not follow, we rewrote.
We build for the hard case
No signal, a cheap phone, a night shift, a first-time user. If it works there, it works everywhere.
We keep the record straight
Who was where, when, and what happened: kept so that it can be shown to a client, an inspector or a court.
Our product
Truepost: every post, proven.
Security guard management software for South African guarding companies, from the guard's phone to the payroll sheet.
- Guards book on at the site with their own phone: GPS, a photo and the time.
- A live control room: who is on post, who is late, which report was missed.
- Rosters, posting sheets and timesheets that follow from each other.
- The occurrence book and PSIRA records, kept as the day happens.
What comes next
The same engine fits other teams that work on site and on shift: cleaning, facilities, farm security, driver teams. We build the next product with a company that needs it, the way we built the first.
Tell us what you needOne product, done properly
We are a small company with one product in the market. We would rather do one thing well for the people who depend on it than list ten things we half do.
About the companyHow we build
Four rules we do not break
Our users are standing at a gate at two in the morning with a basic phone and one bar of signal. Everything follows from that.
It works where the work is
On a gate, in a basement, on a farm. Our software saves first and sends later, because bad signal is normal there.
It runs on the phone people own
We test on entry-level Android phones. If it is slow there, it is not finished.
It says things plainly
Ordinary words, big buttons, one thing at a time. A screen should need no training.
It is honest with people
The person on the phone knows what is recorded about them and why. Records cannot be quietly changed.
