There is no shortage of managed IT providers in Johannesburg. What is short is any agreed meaning for the phrase. It gets used for a service that monitors and patches every machine you own around the clock, and for a service that answers the phone when you call and bills you a fixed amount for the privilege. Both are legitimate businesses. Only one of them is a managed service, and the difference will not be obvious from either website.
So the useful thing is not another list of features. It is the small number of questions whose answers cannot be faked.
Do you hear from them when nothing is wrong?
This is the fastest test there is. A managed service does its most valuable work in the months when you notice nothing at all: patches applied on a schedule, backups restored and verified, an alert investigated at two in the morning and closed before anybody arrives. If the only contact you have with your provider is you contacting them, you are buying support, not management.
Ask what arrives on its own, and how often. A monthly or quarterly report that shows patch coverage, backup verification and what was caught is the artefact of a service that is actually running. If it does not exist, there is nothing to report on.
Who answers, and do they already know your setup?
The gap between a good and a bad experience is almost never technical skill. It is whether the person who picks up has to be told what you run. A provider with a documented environment starts working on the second sentence. A provider without one spends the first twenty minutes rebuilding an understanding of your network that somebody already had and never wrote down.
Ask who answers the telephone at ten past four on a Friday. Ask how many people would recognise your site by name. If the answer routes through an account manager who will pass it on, you have found the layer where things get lost.
What does the contract actually promise?
Response time is the number everybody quotes and it is the least useful one, because responding is not fixing. A useful agreement distinguishes between the two, and says what happens when the second one takes longer than expected.
Read for three things. What counts as a priority one incident, in your words rather than theirs. What the provider commits to outside your trading hours, which is when most of what matters happens. And what is explicitly excluded, because that list is where the surprises live. A contract with no exclusions has not been written carefully; it has been written optimistically.
Is security part of the service or a line item beside it?
This is the question that has changed most in the last few years. It used to be reasonable to buy IT support and then buy security separately. It is no longer reasonable, because the incidents that hurt a business now arrive through the same channel the support team already administers: the identity that opens email, files and the password reset for almost everything else.
Ask whether the team that patches your machines is the team that would investigate a suspicious sign in, and whether they can show you where your environment sits against a recognised framework. The NIST Cybersecurity Framework 2.0 is the usual yardstick, and it is also the one POPIA’s reasonable measures are most often read against. A provider who cannot say where you stand against something external is describing an opinion.
What happens on the day you leave?
Ask it early, and listen for whether the answer is comfortable. Every password, licence, configuration record and warranty position should be documented somewhere you can be handed. Where that documentation does not exist, changing provider stops being a technical project and becomes an archaeology one, and the cost of that is the single biggest reason businesses stay somewhere they have outgrown.
A provider confident in the service they run has no reason to make leaving difficult. One who hesitates has told you where the value is being kept.
Does Johannesburg matter at all?
Less than the search suggests, and more than nothing. Monitoring, patching, identity administration, backup verification and most incident response are delivered remotely, and it makes no difference whether the person doing them is in Sandton or Ballito. What proximity buys you is the day somebody has to stand in the room: a failed switch, a new office, a server that will not come back up.
So the honest question is not whether the provider is local. It is who attends, from where, and how quickly, and whether that is written down anywhere. LANTEK covers Gauteng from an office in Sandton, and the rest of the country remotely from Ballito, which is the arrangement most businesses in Johannesburg will actually experience: somebody nearby for the things that need hands, and a team that never needed to travel for everything else.
Where to start
You do not have to take any of this on trust. A free IT audit and health check is somebody going through your network, your computers, your Microsoft 365 tenant, your security controls and your backups on site, and handing you a written report with an action plan. It comes with a free dark web exposure scan against your domain, and you keep the findings whether you work with us or not.
If nothing in that report surprises you, your current provider is doing their job and we will say so.
