Modernizing mainframe resiliency for AI-ready scale

Broadridge Financial Solutions sits at the center of global capital markets, where mission critical workloads must meet strict standards for security, governance, and continuous availability. Clients now expect real-time experiences, stronger resilience against cyber risk, and tangible AI outcomes. To meet these expectations, Broadridge engaged IBM to extend its modernization strategy around IBM Z® without disrupting market critical processes.

The objectives were clear. Evolve the high performing mainframe core. Provide governed access to trusted data. Prepare for hybrid AI that can scale. IBM sets modernization as a continuous, platform level program that protects past investments while enabling new capabilities across infrastructure, operating system, middleware, security, automation, and AI services. This direction keeps reliability and compliance intact as change accelerates.

Broadridge and IBM advanced a Z first modernization that retains IBM Z as the secure, high-volume backbone for regulated processing. IBM Z Cyber Vault was added to create isolated, integrity checked copies that support clean recovery without reworking the integrated stack. The key modernization step introduced a unified data and API layer, giving governed, high confidence access to foundational data on IBM Z. This enables secure integration with cloud-based services on AWS, while regulated data remains protected on IBM Z.

The hybrid architecture now supports AI driven capabilities for pre-trade discovery and post trade operations, anchored to accurate and trusted data on IBM Z, a resilient infrastructure at market scale. This is modernization delivered as a sustained, platform level program, not a one-time code exercise.

Following this work, Broadridge continues to run between 10 and 12 trillion dollars in U.S. Treasury flows per day on a strengthened IBM Z core, delivering secure and always on operations at market scale. IBM Z reliability also supports about 1% of all U.S. mailers, underscoring proven throughput for regulated communications.

The environment extends IBM Z strengths in security, availability, and transaction integrity, and adds cyber resilience with IBM Z Cyber Vault for SLA based recovery.

A unified data and API layer now enables governed access for on-prem, and cloud aligned AI, simplifying integration with AWS services and reducing onboarding friction. The result is steady modernization with IBM that adds new services while protecting reliability, compliance, and prior investments.
