Simphiwe Mayisela
Cybersecurity Specialist. Integrity Advocate. Voice for Accountability.
Simphiwe Mayisela was a cybersecurity expert at the Public Investment Corporation when, in 2018, he was instructed to reveal the identity of a whistleblower. Guided by professional ethics and a commitment to protecting the whistleblower's disclosure, he faced public reprimand, dismissal, and significant damage to his professional reputation. Once regarded as a leading candidate in his field, Simphiwe’s career trajectory was abruptly altered, losing his livelihood and suffering psychological distress. Today, he runs his own consultancy — rebuilding, redefining, and continuing his work with resilience. His journey reflects the profound personal and professional cost that often accompanies whistleblowing. Simphiwe Mayisela’s story reminds us that accountability is rarely convenient, and integrity is not without consequence. Yet even in the face of retaliation, his decision to speak out contributed to greater scrutiny and reform. We honour his courage. We acknowledge the cost. We recognise the change his actions helped ignite.
