Winterthur Insurance is to start using online trading platform inreon for purchasing reinsurance contracts.
Winterthur is the second major insurer to join inreon - following Axa Corporate Solutions joining last December.
inreon's chief executive Kaj Ahlmann commented: "The backing of such large and prestigious companies is a crucial step in inreon's growth.
"For large insurance groups using the inreon platform enables them to obtain a much better overview of facultative reinsurance purchased. Rates paid and capacity available can all be monitored more effectively," he added.
inreon was founded by Munich Re and Swiss Re in December 2000. It now makes available more than 50% of capacity available from the world's top 25 reinsurers.
