Winterthur Insurance was founded in 1875. It was in its very first year of business that it opened branch offices outside Switzerland. In 1923 it expanded into life insurance business.

Today Winterthur maintains over 28,000 staff in more than 30 countries worldwide. Together with the bank subsidiaries of Credit Suisse Group, it forms one of the world's leading integrated financial services companies. Winterthur focuses on insurance as its core business. It offers private and corporate customers tailor-made insurance and pension solutions at local and international level. In industrial business, Winterthur operates world-wide and is among the world's leading insurers of multinational corporations, while in consumer business it prefers to specialise in selected European markets. Its reinsurance activity is focused on selected market and customer segments.

Its Rechtsschutzversicherung ARAG Schweiz now provides call centre facilities for the domestic market, while its North American interests include link-ups with American Insurance Group and Travelers Property Casualty.
