Our Why
South Africa's family internet filter, built by parents.
GreenLine was born out of a simple conviction: every family deserves safe internet, without needing a degree in networking to set it up. We are a South African company, building for South African families.
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.
How it works
GreenLine uses DNS filtering combined with a WireGuard VPN to intercept and 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.
Because filtering happens in the VPN tunnel, it works on Wi-Fi, mobile data, and any network your family's devices connect to.
