Seacom — enterprise fibre and connectivity provider in South Africa
Seacom launched in 2009 with the first broadband subsea cable along Africa’s eastern seaboard, and now runs a pan-African network of roughly 35,000km of fibre reaching eight countries. Its South African office sits in Anslow Office Park, Bryanston, and the business sells enterprise connectivity rather than consumer packages: IP transit, carrier Ethernet, dark fibre, private lines, cloud services, cyber security and managed networking. Seacom operates across six subsea cable systems and 38 international points of presence.
Key facts

| Network assets | Capacity across six subsea cable systems: the Seacom cable, WACS, TEAMS, EASSy, Main One, Equiano and PEACE |

Infrastructure, not a retail package
Seacom sits a layer below the ISPs most South African buyers deal with. It owns and operates capacity on six subsea systems and a large terrestrial footprint, which means the question is not whether your suburb is covered but whether your site can be reached on-net and what the route looks like. That distinction changes the conversation entirely: you are buying a circuit with a defined path, latency profile and service level rather than a monthly speed tier. Businesses with multiple African sites, or with a real need for international transit, are the natural fit here. Ask for the route map and the restoration path, because on a subsea network those two answers decide what happens on a bad day. Retail-scale alternatives are listed in the fibre provider directory.
Who Seacom is a fit for
- Enterprises with sites in more than one African country
- ISPs and carriers buying IP transit or wholesale capacity
- Businesses needing dark fibre or private lines with a defined route

What does Seacom actually sell?
Enterprise and wholesale connectivity: IP transit, carrier Ethernet, dark fibre, private lines and enterprise access, with cloud and security services layered on. It is not a consumer fibre package provider.
When was Seacom founded?
Seacom launched in 2009 with the first broadband subsea cable serving Africa’s eastern seaboard. The network has since grown to roughly 35,000km of fibre across eight countries.
Which countries does Seacom reach?
South Africa, Kenya, Uganda, Tanzania, Mozambique, Rwanda, Mauritius and Djibouti, with onward routes to Europe and Asia through 38 international points of presence.
Can a small business buy from Seacom?
The offering is built for enterprises, carriers and ISPs. A small business is usually better served buying from an ISP that rides this kind of network, since the commercial minimums and the contracting model are built for scale.
What does Seacom cost?
There is no published rate card. Circuits are priced by route, bandwidth, contract term and service level, so a quote is the only meaningful figure.
How many subsea cables does Seacom use?
Six systems carry its capacity: the Seacom cable itself plus WACS, TEAMS, EASSy, Main One, Equiano and PEACE. Multiple systems matter because they give the network more than one way around a cable break.
