The speed you notice online is not only about how fast your line is. It is also about latency: how long a signal takes to reach a server and come back. Light in fibre is fast, but not infinitely so, and South Africa is far from Europe, North America and Asia. Every route out of the country runs over long undersea cables along the African coasts.

That is why the choice of VPN server matters more here than in many places. Connect through a server on another continent and South African sites will feel slow, because each request travels out and back again. Connect through a server in South Africa and local banking, shopping and news stay on a short path.

The same logic applies in reverse to South Africans abroad, from London to Perth to Toronto. Their own connection is fine, but South African services decide what to show by checking the IP address of each visitor. Public broadcasting, pay TV, sport and some local shops are licensed or built for customers in the country, and they look for a South African address before anything else.

Privacy is the third piece. South Africa's Protection of Personal Information Act, known as POPIA, sets rules for how companies handle personal data, and it has made people more aware of what is collected about them. A VPN adds a layer of its own: on the free Wi-Fi of a mall, an airport or a coffee shop, everything you send stays encrypted, and the network sees only a connection to the VPN server.

Browsec has more than 8,000,000 users worldwide, and for those in and from South Africa these three reasons, distance, location and privacy, usually come together.
