African Businesses Face Rising Cybersecurity Risks from WhatsApp at Work, Survey Finds

A new survey by KnowBe4 has revealed a critical cybersecurity blind spot for African businesses: the widespread reliance on WhatsApp for workplace communication. With 93% of professionals across the continent using the app for work, companies face mounting risks ranging from data breaches to regulatory non-compliance.

The report identifies data leakage as the most pressing threat, with employees frequently sharing sensitive client information, financial data, or login credentials in informal and uncontrolled settings. This “shadow IT” use bypasses corporate oversight, leaving businesses vulnerable.

Other dangers include phishing and impersonation attacks, often triggered by SIM swap fraud, where scammers hijack accounts to trick colleagues and clients. The survey also highlights the blurring of personal and professional boundaries, fueling employee burnout, and the absence of compliance-ready audit trails in regulated sectors such as banking, healthcare, and law.

The problem is amplified by the fact that 80% of respondents use personal, unmanaged devices for work, devices that often lack corporate-grade security protections. Even WhatsApp’s end-to-end encryption is not enough—third-party integrations may still expose data.

KnowBe4 recommends companies establish formal communication policies, adopt enterprise-grade platforms such as Microsoft Teams or Slack, and provide continuous mobile-centric security training. For customer engagement, the WhatsApp Business API offers stronger safeguards and analytics, especially when deployed with official solution providers.

While WhatsApp remains an indispensable tool in Africa’s digital economy, the survey warns that without stronger controls, businesses risk paying the price in scams, leaks, and compliance penalties.
