Tokio Marine HCC Elevates Gülsah Dagdelen to Lead Cyber Insurance Team
Tokio Marine HCC has appointed Gülsah Dagdelen as the new head of its international cyber insurance team, succeeding Xavier Marguinaud. With nearly two decades of experience, Dagdelen aims to navigate the complexities of the evolving cyber insurance landscape.

In a significant move within the insurance industry, Tokio Marine HCC International (TMHCCI) has appointed Gülsah Dagdelen as head of its international cyber team, a role she officially began on July 1. This change comes after a decade-long tenure of Xavier Marguinaud, who was instrumental in developing TMHCCI's cyber offerings from a singular financial lines product into a comprehensive international practice. Dagdelen's ascension marks a pivotal moment for TMHCCI as it seeks to enhance its cyber insurance capabilities in an increasingly complex risk environment.
Dagdelen's rise to leadership is backed by her extensive experience in underwriting, particularly in the financial lines and cyber sectors. Joining TMHCCI in 2013, she transitioned into cyber insurance in 2019, bringing with her nearly two decades of technical and commercial underwriting expertise. Her appointment is not only a recognition of her capabilities but also a strategic move to maintain continuity within the cyber team, which is poised to address the growing demand for cyber insurance in an era marked by rapid technological advancements.
The Evolution of Cyber Insurance at TMHCCI
Under Marguinaud's leadership, the cyber insurance practice at TMHCCI flourished, establishing a robust foundation that Dagdelen is now set to build upon. Over the last decade, the demand for cyber insurance has surged, driven by escalating threats such as ransomware attacks, data breaches, and cyber extortion. TMHCCI's cyber team has grown to include 22 specialists, including a dedicated cyber security unit, reflecting the company's commitment to addressing these emerging risks.
The company's trajectory aligns with broader trends in the cyber insurance market. According to a report from Munich Re, the global cyber insurance market was valued at approximately $15.3 billion in 2024 and is projected to more than double by 2030. This growth underscores the increasing need for businesses to secure comprehensive coverage against cyber threats.

The Role of Leadership in Navigating Cyber Risk
Dagdelen's leadership style is characterized by a focus on disciplined underwriting and the cultivation of strong relationships with brokers and clients. As the cyber risk landscape continues to evolve, her emphasis on collaboration and communication is critical. In her own words, she expressed pride in the team's accomplishments and excitement about steering the team into its next chapter.
Her approach is particularly relevant as the cyber insurance market experiences fluctuations in pricing and an uptick in claims activity. Recent reports indicate a period of rate softening, which could create challenges for insurers in balancing risk with profitability. Dagdelen's experience and strategic vision will be crucial in navigating these complexities while ensuring the team maintains its reputation for underwriting discipline and specialized knowledge.
Key Challenges Facing the Cyber Insurance Market
The cyber insurance landscape is fraught with challenges that both insurers and businesses must contend with. As Dagdelen steps into her new role, several key issues loom large:
- Ransomware Threats: Ransomware continues to be a leading concern, with attacks targeting businesses of all sizes. Insurers must adapt their coverage offerings to address the unique risks associated with ransomware, including the potential for significant financial losses.
- Supply Chain Vulnerabilities: The technology supply chain is increasingly susceptible to cyber threats, necessitating a reevaluation of coverage options to include broader protections against third-party risks.
- Cloud Concentration Risks: As more businesses migrate to cloud-based solutions, the concentration of data in a few providers presents distinct vulnerabilities that must be factored into underwriting decisions.
- Regulatory Changes: Evolving cybersecurity regulations at both state and federal levels will impact policy requirements and compliance standards, presenting additional challenges for insurers.

The Future of Cyber Insurance
Looking ahead, the landscape for cyber insurance is poised for transformation. The increasing sophistication of cyber threats necessitates that insurers not only provide coverage but also actively engage in risk management strategies with their clients. This paradigm shift requires a deeper understanding of clients' operations and the specific risks they face.
As Dagdelen leads TMHCCI's cyber team, her strategic vision will be critical in fostering partnerships with clients that extend beyond traditional insurance offerings. This involves working collaboratively to implement preventative measures, risk assessments, and ongoing education about emerging threats. By aligning underwriting practices with clients' evolving needs, TMHCCI aims to solidify its position as a leader in the cyber insurance market.
