LONDON, 17 February 2005 – Aon Limited, the UK’s largest insurance broking and risk management company, has certified the SOAP  gateway products of three technology suppliers - Innovation Process Technology (IPT), Brixlogic, in partnership with Sun Microsystems, and Web Connectivity - who can provide a simple, cost effective solution to help connect trading partners to its electronic messaging platform, Aon Broking Connections (ABC).

Many insurance companies are eager to reduce costs and time by conducting insurance business electronically but may lack the necessary resources, skills or budget to build their own electronic gateway to ABC. Aon has worked closely with leading specialist providers IPT, Brixlogic-Sun and Web Connectivity to ensure that their solutions will allow insurers to get the full benefits of connecting to ABC without incurring high license or implementation costs. Each of the certified solutions has been assessed to ensure its compliance to the ACORD industry messaging standards and its compatibility with the ABC platform.

Anne Boden, chief information officer of Aon Limited, said: “The appointment of three certified technology suppliers represents the next significant phase in the development of Aon Broking Connections (ABC). Insurers keen to use ABC, but who might not have sufficient resources, skills or budget, now have an easily accessible and cost effective solution to enable them to conduct business with Aon electronically. This can only be good news in the drive to harness the efficiencies that technology can bring to the insurance marketplace.”
