When Sabur Ajao earned his Certified Information Systems Security Professional (CISSP) credential in 2020, he joined an elite group of fewer than 1,000 Nigerians holding this globally recognised certification. Sabur, who suffers from progressive hearing loss that required cochlear implant surgeries in his two ears, now works as a consultant at McKinsey & Company. He represents one of only a handful of professionals worldwide navigating this unique intersection of experiences and achievements.
According to the U.S. National Deaf Centre, only 55 percent of deaf or hard-of-hearing individuals maintain employment, compared to 70 percent of the general population. For those who do work, median earnings typically trail significantly behind hearing peers.
The challenges are even more pronounced in technical fields, such as cybersecurity, where certifications like the CISSP require hundreds of hours of training, much of it traditionally delivered through audio-based instruction. Combined with the communication demands of consulting, these barriers make Ajao’s career achievements even more exceptional.
Building excellence from Lagos
Ajao’s career journey began at Oando Energy Resources in Lagos, where he led cybersecurity initiatives that achieved ISO certification and dramatically strengthened the organisation’s security system.
His work garnered attention across the Nigerian tech ecosystem, resulting in engagements with major local and international firms.
“What set Sabur apart was his ability to translate complex technical requirements into business value,” recalls a former colleague who worked with him on several transformation projects. “That skill would prove invaluable in his later career.”
Transforming challenge into opportunity
After gaining admission to Northwestern University’s Kellogg School of Management, Ajao faced a critical decision when progressive hearing loss threatened his academic and professional career. Rather than be discouraged, he underwent cochlear implant surgeries in early 2023, testing the new technology during a high-stakes consulting internship.
“I knew that succeeding in consulting, a field that requires the finest listening skills, would help validate not just my decision to have the surgeries, but show others what’s possible with modern cochlear technology,” he explains.
The strategy worked, as Ajao excelled in his internship and subsequently secured a full-time position at McKinsey, where he now leads cybersecurity and technology initiatives for major global clients.
Creating wider impact
Beyond his day-to-day work, Ajao serves as a mentor with Advanced Bionics, a leading cochlear implant manufacturer, after being selected through a competitive process. He supports families across the world who want to access hearing treatment.
His approach fills an important gap in patient care. As Northwestern Medicine’s cochlear implant programme has noted, technical medical information often isn’t enough; patients need to see successful professionals who share their experience. Ajao provides that crucial perspective, helping prospective patients understand what they are getting and how the cochlear implant can improve their lives.
His patient advocacy work recently earned recognition from Poets & Quants, a leading business publication, where his story prompted the editor-in-chief to publicly acknowledge his own hearing challenges for the first time, demonstrating the ripple effects of visible representation.
Bridging continents and communities
In Nigeria, while 6.2 percent of the population is estimated to suffer from disabling hearing loss, according to the Federal Ministry of Health, very few have access to modern hearing technology or treatment. This is why Ajao has maintained strong ties to Nigeria’s tech ecosystem in his advocacy for improved hearing tech access in the country.
He regularly speaks to healthcare professionals about patient-centred care and works to demonstrate the economic returns of investing in disability support.
“In Nigeria and across Africa, hearing technology remains financially out of reach for most,” he notes. “Part of my mission involves showing that supporting people with disabilities isn’t charity, it’s an investment that enables extraordinary contributions.”
Looking ahead, Ajao aims to launch ventures addressing both cybersecurity resilience and healthcare accessibility in emerging markets. His vantage point spans technical excellence, business strategy, and lived experience with disability, positioning him to identify opportunities others might miss.
“Whether securing critical infrastructure or expanding access to life-changing medical technology, the goal remains consistent,” he reflects. “Remove barriers that prevent people from reaching their full potential.”
For Nigerian professionals navigating their own challenges, Ajao’s message resonates: “Excellence isn’t about perfect conditions. It’s about converting every experience — especially the difficult ones — into capabilities that create distinctive value.”
