SD-WAN: transforming connectivity for distributed enterprises

SD-WAN, an answer to connectivity challengesThe Software-Defined Wide Area Network (SD-WAN) virtualizes inter-site connectivity by intelligently combining different types of links (MPLS, fiber, 4G/5G, Internet). In Africa, where connectivity is often costly and unreliable, SD-WAN offers a particularly relevant solution.Measurable benefitsWAN cost reductions reach 40 to 60% thanks to the use of Internet links to complement or replace MPLS. Quality of service is maintained through intelligent routing that selects the best path in real time. The rollout of new sites is reduced from weeks to hours.Use cases in AfricaMulti-site enterprises (banks, retail, telecoms) are the first to benefit. SD-WAN makes it possible to aggregate several low-cost Internet links to achieve reliable connectivity. Automatic failover between links ensures service continuity.Choosing the right solutionAssess ease of deployment, built-in security capabilities (firewall, IPS), the quality of monitoring, and support in Africa. Cisco Meraki, Fortinet, and VMware SD-WAN are the most widely deployed solutions on the continent.Source: Zeus Kerravala, founder of ZK Research, Le Monde Informatique, February 2026
