London, 2 February 2026: Tokio Marine Kiln (TMK), a leading specialist insurer, today announces it has appointed Ben Sitki as an Underwriter within its Cyber Reinsurance Solutions team. He takes up his new role with immediate effect and will report to Cesar Silvestre, Head of Cyber Reinsurance Solutions.

Sitki brings nearly two decades of (re)insurance experience to his new role, with particular expertise in developing cyber solutions for businesses in the Middle East and Africa. He joins from Guy Carpenter where he served, most recently, as Senior Vice President, and has previously held roles at Willis Re and Canopius.

The appointment follows the launch of TMK's cyber reinsurance offering in November, with Cesar Silvestre joining to lead the department, and builds on the introduction of its flagship cyber insurance product TMK Cyber Ctrl and its market-first product Enterprise Ctrl.

Cesar Silvestre, Head of Cyber Reinsurance Solutions at TMK, said:

"We're delighted to welcome Ben to the team. His extensive cyber experience, and proven ability to build client relationships and develop new markets, makes him an excellent addition as we continue to grow our cyber reinsurance capabilities.
