Secure
Protect the basics attackers reach for first.
IT, security and AI for small South African businesses
IT that is secure, keeps running, and works harder for you.
Sys-Ki is a one-person practice for owner-run businesses. We lock down your email and accounts, keep the office running day to day, and build the automations and AI workflows that save real time. Fixed prices, plain English, and clear limits.
Fixed price, agreed before work starts. Monthly plans available.
Eight services, one practice. Every node links to its service.
Three areas. Eight services. One accountable practice.
Run
Keep the office and its systems working day to day.
Build & automate
Make repetitive work disappear, and use AI where it earns its place.
How we work
- 01
Talk
Tell me what is going on, even roughly. If I am not the right fit, I will say so.
- 02
Plan
We write down what we will do, what we will not do, and a fixed price, before any work starts.
- 03
Do
I do the work and explain each change in plain English, so you know what changed and why.
- 04
Keep it running
Fixed means fixed. Monthly plans are there for the work that never really ends.
Play with how it actually works.
Three short, interactive explainers. Change a setting, step through a process, and see what happens. Built to be used with a keyboard and with reduced motion.
Interactive
How someone sends email pretending to be you
Step through a spoofed invoice and see how SPF, DKIM and DMARC stop it, and how a bad setting can block your own mail.
Interactive
What a well-run small-office network looks like
Switch controls on and off and watch what a visitor, a stolen laptop or a phishing click can actually reach.
Interactive
How an AI workflow handles an invoice
Follow one invoice from inbox to accounting, and see exactly where a person has to approve it.
Free tool
Sys-Ki Health Check
A free, passive check of your domain's email settings, with a plain-English report. A starting point, not a sales call.
From the founder
I am Karim, a security engineer in Johannesburg.
Sys-Ki is my one-person practice for South African businesses that need IT to just work, stay secure and use AI sensibly. You deal with me directly, from the first conversation to the last. I would rather tell you that something is not for us than sell you something you do not need.
More about how Sys-Ki worksTell me what is going on.
A short note is enough. I will reply with what I would do, and what it would cost, before anything starts.
