Gallagher Bassett: From Mainframe to Modern Data Capabilities and a New Business Model

Gallagher Bassett, a leading insurer, serves 4,800 organizations across various industries and manages claims in over 60 countries. We helped Gallagher Bassett add modern data capabilities to their existing mainframe legacy infrastructure without a single legacy system restructuring effort.

The result of this effort allowed customers access to their data and aggregated analytics faster than ever before and provided a new value-added revenue stream for Gallagher Bassett.

Modern capabilities, legacy infrastructure

With all of Gallagher Bassett’s claims processing data in a mainframe environment, it was impossible, due to systems limitations, to create raw data feeds and analytics in a short period of time.

As part of our strategy, we established a hybrid Azure cloud and on-premises solution that allowed our client to provide modern and fast data capabilities on top of their current legacy environment. No significant changes were made to their existing environment. 

The boost in performance, reliability, and scalability enabled Gallagher to continue to grow at a non-linear rate without worrying about the technical limitations of their data reporting and analytics platforms.


A new data revenue stream

Gallagher’s business objective was to make aggregate claims available to customers and make it as easy as possible to consume them.

As a result of our work, we enabled clients, via a secure API, to request information for thousands of claims and insurance policies at an unprecedented rapid refresh rate of four times per day, exposing the data for on-demand data consumption. 

This new rate of processing information resulted in a new revenue model (and SaaS product), which continues to grow. Clients are now able to receive their claims data in an unprecedented time, with the new ability to quickly aggregate claims data as part of an additional offering.


A pragmatic approach with big outcomes

A common misconception is that modernization always involves replacing legacy systems, hiring a ton of tech resources, and engaging in a multi-year digital transformation project. That’s not correct.

The migration to the cloud enables Gallagher Bassett to continue with their business innovation without legacy systems acting as a limiting factor. Additionally, their new cloud infrastructure and API framework allow Gallagher to add new tools and services on top of this platform without worrying about their current legacy systems. 


A (tech) look behind the scenes

We created a hybrid solution that joined Gallagher Bassett’s on-premises data centers with Azure Cloud. We leveraged the Azure Data Warehouse as the main platform and created data pipelines using the Azure Data Factory to transfer data from on-premises systems to their new Azure cloud.

To make the transition possible, we went through a cloud provisioning and enablement process that met strict security requirements and ensured that the internal operations team was ready to manage the new cloud environment.
