As digital acceleration reshapes the global business landscape, cybersecurity can no longer be treated as an isolated function, according to cybersecurity expert Omoshalewa Adeosun. She argues that cloud security and third-party risk must be elevated to core business priorities in 2025, warning that neglect in either area now constitutes an existential threat to organisations.
Adeosun, a consultant with a leading technology firm, believes the convergence of widespread cloud adoption and the increasing reliance on external vendors has created a complex and high-stakes ecosystem. Speaking on the evolving digital environment, she cautioned that negligence is no longer simply risky but potentially catastrophic.
Adeosun’s journey into cybersecurity began with an early fascination for the mechanics of technology, later shaped by years as an IT analyst. Determined to deepen her understanding, she pursued a master’s degree in Applied Cybersecurity in the United Kingdom. Her approach is distinguished by a blend of academic rigour and practical expertise, supported by certifications such as CompTIA Security Plus and ISO 27001 Lead Implementer. Her thought leadership is further recognised through peer review roles with respected journals including IJLTEMAS and IJRISS.
When asked about the most pressing concerns facing businesses, Adeosun pointed to the vulnerabilities inherent in cloud environments and third-party partnerships. “Many businesses falsely assume that cloud service providers bear full responsibility for security,” she said. “In reality, it is a shared responsibility. Client-side misconfigurations or lax access controls can leave systems dangerously exposed.”
Similarly, she highlighted the dangers posed by third-party vendors, noting that even robust internal security frameworks can be undone by weaknesses elsewhere. “You are only as secure as your weakest link,” she warned. “A breach through a third party can be as devastating, if not more so, than an internal compromise.”
Adeosun advocates for strict vetting processes, continuous vendor monitoring, and the full integration of third-party risk management into enterprise-wide security strategies. Her emphasis lies not only in technical solutions but also in translating complex policies into actionable, accessible guidance for employees at all levels.
During her time with her current firm, she spearheaded efforts to reengineer security documentation, demystifying technical jargon to make it relatable and practical. Her initiatives included the development of a dynamic, behaviour-based security awareness programme featuring simulated phishing attacks, microlearning sessions, and real-time threat response drills, resulting in a measurable drop in human error incidents.
Beyond employee education, Adeosun has played a key role in strengthening organisational resilience through advanced threat intelligence and proactive vulnerability management. In one notable project, she led the creation of a continuous vulnerability scanning system, prioritising risks by impact and exploitability, significantly reducing the firm’s exposure window.
Her expertise also extends into multi-cloud security environments, where she has worked to harmonise fragmented configurations and eliminate inconsistencies that often leave organisations vulnerable.
Despite her technical acumen, Adeosun’s driving motivation remains the human element of cybersecurity. She is committed to knowledge sharing, evident in her work training students, reviewing academic research, and promoting a more human-centric approach to security.
Looking ahead, Adeosun envisions a cybersecurity paradigm shift where resilience, adaptability, and intelligence are prioritised over simple prevention. She predicts greater integration of AI in threat detection, refinements in cloud-native security architecture, and a growing expectation that boards of directors will treat vendor risk management as a strategic issue.
“The future of cybersecurity is not just about preventing attacks,” she said. “It is about anticipating them, surviving them, and emerging stronger. Cloud security and third-party risk are no longer optional concerns—they are essential business imperatives.”
In a world where digital trust is a form of currency, Omoshalewa Adeosun continues to challenge complacency, advocate for excellence, and inspire a vision of a safer, more resilient digital future.
