Teneo is strengthening the integration of cybersecurity within its financial advisory offering through the appointment of Serdar Cabuk, underscoring the growing convergence of cyber risk, transactions and crisis management.
Cabuk joins the firm as a senior managing director in its London-based financial advisory business. In this role, he will focus on expanding Teneo’s cybersecurity advisory capabilities while working closely with leadership teams to address cyber risks across transactions, restructuring scenarios and crisis situations.
The firm’s cybersecurity advisory practice combines expertise from its forensic, risk advisory, and strategy and communications teams, positioning cyber risk alongside financial and operational considerations in complex, high-stakes corporate environments.
In collaboration with the risk advisory team, Cabuk will help develop core cybersecurity capabilities and drive their rollout across EMEA and other regions. He will also support organisations in managing cyber exposures as part of their broader risk landscape.
Extensive experience across consulting and technology
Cabuk brings more than two decades of experience spanning cybersecurity, technology and risk consulting, including senior positions within the Big Four and IBM. His expertise includes cybersecurity strategy, incident response and recovery, as well as navigating regulatory and technological developments.
He has advised clients across sectors such as financial services and energy, with a focus on embedding cybersecurity into M&A due diligence, pre-IPO assessments, complex supply chains and the adoption of emerging technologies.
Prior to joining Teneo, Cabuk served as UK lead partner for risk consulting and energy consulting at KPMG. He has also led Deloitte’s Nordic cyber business and held a senior leadership role within IBM’s European security consulting division. Earlier in his career, he contributed to the development of secure payments systems at Visa Europe and conducted trusted computing research at HP Labs, where he was awarded industry patents.
Part of broader expansion across advisory services
The appointment forms part of a wider series of hires and strategic developments across Teneo’s advisory platform. In March 2026, the firm appointed three senior managing directors to its global forensic practice to enhance capabilities in investigations, compliance and data-driven analysis, reflecting rising demand for cross-border regulatory work.
During the same period, Teneo also expanded its political risk advisory unit with the addition of senior advisers, including former officials from intelligence and defence agencies, highlighting increasing demand for geopolitical insight in corporate decision-making.
Further hires across management consulting, strategy and communications, as well as advisory roles in Asia, signal continued investment across key service lines and regions.
Earlier initiatives include the launch of a financial advisory practice in Australia following the acquisition of PwC’s former restructuring business, adding more than 80 professionals to Teneo’s restructuring platform.
Teneo operates as a global CEO advisory firm, delivering services across five core segments: financial advisory, management consulting, risk advisory, and strategy and communications. Its work spans transactions, restructuring, governance, investor relations and risk management.
