How do you manage and modernize 90+ legacy systems without breaking what already works?
Here’s the scenario: You’re managing millions of transactions daily. Your customers expect digital-first service. Your systems? A patchwork of legacy platforms that need to be managed, integrated, and kept compliant — while delivering seamless service.
CAIXA faced exactly this. As Brazil’s largest government-owned financial institution with 68% of the mortgage market, they couldn’t afford downtime. But they also couldn’t keep running on outdated infrastructure with fintech competitors breathing down their neck.
The technical challenge:
- Manage and integrate 90+ internal systems across mainframe, COBOL, Java, and Microsoft platforms
- Support 8,000 simultaneous users across multiple channels
- Ensure operational excellence while processing 120,000 transactions per minute with zero disruption
- Migrate to cloud while maintaining regulatory compliance
- Do it all without impacting 27.5 million existing contracts
Working with Unisys, CAIXA built a solution that delivered:
- 99% uptime while processing 4,500 daily loan originations
- Seamless integration via 280 APIs
- Significant cost reduction through automation
- Full Azure cloud migration with enhanced security
Same legacy complexity. Different outcome.
