Our mission
Make powerful parental controls accessible and affordable for every South African family.
Our team
A small team of parents and engineers who use GreenLine at home every single day.
Our reach
Protecting families across South Africa, from Cape Town to Limpopo.
Our Why
The world changed faster than families were prepared for.
Technology moved from being a tool we used… to a force quietly shaping habits, attention, and even values inside our homes. Not because parents stopped caring — but because the systems became stronger than the structures within the family.
I believe parents should not feel powerless in their own homes.
Leadership in a family matters. Guidance matters. Intentional boundaries matter. When those begin to erode, the solution isn't fear or control — it's clarity and structure.
That's why I chose to build.
Not because it was easy.
Not because it was safe.
But because responsibility is more important than comfort.
Families deserve systems that strengthen the home — not compete with it.
How it works
GreenLine uses DNS filtering over a secured VPN connection to filter internet traffic at the DNS level. When a device queries for a blocked domain, our server returns a safe response instead — preventing the content from loading entirely, before any data is transferred.
GreenLine is also based on accountability. When adding a device you enter the email addresses of your accountability partners, who will be notified of all blocked site attempts.
Because filtering happens in the VPN tunnel, it works on Wi-Fi, mobile data, and any network your family's devices connect to.
