Lockton Re has appointed Emily Chillingworth (pictured above) as head of cyber analytics, adding dedicated actuarial capacity to the reinsurance broker's cyber team as it works to close a persistent modeling gap in one of the market's fastest-growing lines.
Chillingworth joins from Gallagher Re, where she spent more than six years in actuarial and analytics roles. She most recently served as head of cyber actuarial, a position she held from June 2024, after four and a half years as an actuary within the firm's analytics specialty team.
Before Gallagher Re, she worked as a consultant at Willis Towers Watson for nearly six years. Her career in the London reinsurance market spans more than a decade.
Ed Le Flufy, Lockton Re's global head of cyber, said the hire will strengthen the firm's cyber analytics capabilities.
"Her experience building and leading dedicated Cyber Actuarial and Analytical capabilities is going to be invaluable as we build out Lockton Re's Global Cyber proposition," Le Flufy said.
The appointment comes as the cyber reinsurance sector contends with a structural data gap. Industry estimates place the global cyber insurance market at between $16 billion and $20 billion in 2025, with projections for 2030 ranging from $30 billion to $40 billion or higher. The sector has recorded a compound annual growth rate above 20% since 2015, occasionally surpassing 30%.
In a September 2025 report, Lockton Re identified three priorities for the next phase of cyber reinsurance growth: improved data quality for understanding portfolio risk, continued investment in granular risk modeling to address systemic threats, and flexible product offerings to reach underserved segments.
Oliver Brew, head of Lockton Re's Cyber Center of Excellence, noted that there have been only "a handful of true cyber catastrophe events," leaving limited data points to understand how a technology incident would affect multiple companies simultaneously.
Chillingworth is expected to develop actuarial approaches to modeling cyber risk exposures — a domain where the intersection of cyber analytics and underwriting is increasingly central to how reinsurance intermediaries price and structure coverage.
She is a Fellow of the Institute and Faculty of Actuaries and holds a first-class master's degree in mathematics from the University of East Anglia.
