As South Africa invests billions in modernising its ports, cybersecurity experts have warned that protecting digital infrastructure is becoming just as important as upgrading physical assets.

South Africa's ports are becoming increasingly digital as operators invest in modern technology to improve efficiency, reduce delays and strengthen the country's logistics network.

However, cybersecurity experts have warned that as ports become smarter, they also become more vulnerable to cyberattacks that could disrupt trade and cost the economy billions.

Martin Fernandes, Business Development Manager for Operational Technology in Africa at Fortinet, said modern ports are no longer simply physical infrastructure but complex digital ecosystems where every connected system plays a role in keeping cargo moving.

"A modern port is now part of a much larger digital trade ecosystem where all systems need to work together. If one part of that ecosystem is disrupted, the impact can move quickly through the supply chain," Fernandes said.
