Teneo is embedding cybersecurity into its financial advisory operations with the appointment of Serdar Cabuk, pointing to a closer link between cyber risk, transactions and crisis response.
Cabuk joins as a senior managing director in the firm’s financial advisory business, based in London. His remit includes developing cybersecurity advisory capabilities and working with leadership teams on cyber risk in transactions, restructuring situations and crisis events.
Teneo’s cybersecurity advisory practice brings together expertise from its forensic, risk advisory and strategy and communications teams. The firm positions cyber risk alongside financial and operational considerations in high-stakes corporate situations.
Cabuk will work with the risk advisory team to build core cybersecurity capabilities and take them to market across EMEA and other regions. He will also advise companies on managing cyber exposures within broader business risks.
“It is an exciting time to join Teneo as I enter my third decade in cybersecurity, having witnessed its evolution from a technical niche into a core business resilience issue requiring expert, multidisciplinary advisory. I look forward to working alongside my colleagues to support clients through complex, high-stakes challenges – from geopolitics and insolvency to crisis management and cyber incidents – leveraging and growing Teneo’s truly global, borderless team,” said Cabuk.
Cabuk has more than 20 years of experience in cybersecurity, technology and risk consulting, including senior roles across the Big Four and IBM. His work covers cybersecurity strategy, incident response and recovery, and regulatory and technology developments.
He has advised clients in financial services and energy, with experience integrating cybersecurity into M&A due diligence, pre-IPO valuations, complex supply chains and emerging technology adoption.
“Serdar’s appointment marks an important step in the continued expansion of our global business. As cyber risk becomes increasingly central to financial, operational and reputational resilience, his expertise strengthens our ability to deliver integrated, senior-led advice across the most complex client challenges. Bringing cyber strategy, resilience and response capabilities into our global Forensic practice, while deepening collaboration with our Risk Advisory and Strategy & Communications teams, enhances our ability to provide a truly coordinated, end-to-end offering,” said Dan Butters, chief executive of financial advisory at Teneo.
Before joining Teneo, Cabuk was UK lead partner for risk consulting and energy consulting at KPMG. He previously led the Nordic cyber business at Deloitte and held a leadership role in IBM’s European security consulting business. Earlier roles included developing secure payments systems at Visa Europe and contributing to trusted computing research at HP Labs, where he received industry patents.
“We are delighted to welcome Serdar to Teneo. His appointment strengthens our Forensic practice, adding a critical cyber dimension, while building on Teneo’s established cyber and risk capabilities in the U.S. to deliver a truly integrated, global solution. Our Forensic practice is intentionally aligned to today’s most critical issues. As cyber risk continues to rank among the most significant threats facing CEOs and boards, Serdar’s expertise is a natural addition – enhancing our ability to support clients across the full spectrum of forensic matters, from incident response through to investigation, recovery and resilience,” said Christian Butter, head of forensic UK and EMEA at Teneo.
The appointment sits within a broader series of hires and acquisitions across Teneo’s advisory platform. In March 2026, the firm added three senior managing directors to its global forensic practice to support investigations, compliance and data-led analysis, according to company statements. Those hires were positioned around increased demand for cross-border investigations and regulatory work.
During the same period, Teneo appointed senior advisers to its political risk advisory unit, including former senior officials from intelligence and defence agencies, citing demand for geopolitical insight in corporate decision-making.
Additional hires in management consulting, strategy and communications and Asia-based advisory roles have also been announced in recent months, indicating continued investment across service lines and regions.
Earlier developments 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 the firm’s restructuring capability.
Teneo operates as a global CEO advisory firm offering services across five business segments, including financial advisory, management consulting, risk advisory and strategy and communications. Its work spans transactions, restructuring, governance, investor relations and risk.
