About Us


Sirius International is a separately capitalized company within Sirius International Insurance Group Ltd. Decades of stability and the Group's multi-billion dollar capital structure lends further credence to the solid financial strength of Sirius. Sirius International, with its head office in Stockholm, services clients and brokers all over the world, although more than 50% of the portfolio emanates from Europe. We also work closely with the other operating units in the Group, notably with Sirius America.
