Web filtering, described honestly
Categories are blocked at the network rather than on the device, so it applies to every phone that connects and there is nothing to install. Adult, gambling, torrent and — if you want it during lessons — social media, on a timetable. It is a category filter and it is not infallible: a determined sixteen-year-old on a VPN will get past it, as they will past any school filter. What it does reliably is stop the accidental, keep the network clean, and give you a log of what was blocked and when.
Three more for a school
A code per class or per year group, revoked at the end of term without touching a device.
5 Mbps per device keeps four hundred phones from flattening the line during break.
One SSID from the science block to the sports field, no re-login between periods.
Which hardware path
Access points and a router, shipped configured.
One MikroTik goes in front of what you run today.
Dual-SIM routers for vehicles.
Schools nearly always have an estate already, often part-funded, and it stays in place.
What it costs on a campus
Ten access points is the cap for a site and covers a small campus: two blocks, a library and a hall. Larger schools are quoted as several sites.
That is the ceiling — 10 APs, 80 concurrent users, R1,500 a month, whatever the count.
"The students will find a way around it."
Some will. A category filter stops the accidental and the casual — the link in a group chat, the site that autoplays something in a corridor — and it holds against most of what a school actually deals with. It does not beat a paid VPN on a personal phone, and anyone who tells you their filter does is selling. What you get alongside it is a log: which category, which device, what time. That is usually what a conduct conversation needs.
Tell us the blocks and the student count and we will size it.
