Telkom

Telkom SA SOC Limited, commonly known as Telkom, is a telecommunications provider headquartered in South Africa. The company delivers essential communication services, including mobile network operations, digital customer service platforms, and voice systems. Its infrastructure supports USSD menus, mobile applications, voicemail capabilities, and call center operations, serving both individual and business customers across its markets. The organization's operations emphasize maintaining critical connectivity services, with digital platforms forming a core component of its customer engagement strategy.

Telkom has demonstrated specialized competency in cybersecurity incident response and infrastructure resilience. During the 2017 WannaCry ransomware attack, the company successfully prevented file encryption across its systems despite sustained malicious traffic overwhelming network defenses. Its technical teams implemented traffic throttling in high-risk segments and maintained continuous monitoring to safeguard data integrity while restoring services. Although the attack caused multi-day service disruptions affecting mobile apps, voicemail, and call centers, Telkom achieved partial overnight recovery through coordinated defensive measures. The incident highlighted the organization's focus on preemptive vulnerability management, with explicit emphasis on patch deployment to counter evolving ransomware threats. This operational approach reflects Telkom's prioritization of maintaining service continuity under sustained cyber attacks within its telecommunications ecosystem.
