Digital excellence isn’t optional in today’s financial landscape, it’s the standard.
When one of the largest U.S. financial institutions needed to modernize more than 110 mission-critical internal applications, they partnered with Prolifics to turn years of tech debt, fragmented workflows, and compliance challenges into a scalable, secure, and future-ready ecosystem.

The Client: A Top U.S. Financial Institution Ready for Change

This institution serves millions of customers through extensive retail, commercial, and investment banking operations. But behind the scenes, over 110 internal applications were built on outdated platforms, including:

  • Microsoft Access
  • Visual Basic (VB)
  • Excel VBA
  • ASP
  • Lotus Notes

These legacy systems had become:
❌ Costly to maintain
❌ Difficult to update
❌ Misaligned with IT & security standards
❌ Bottlenecks to compliance and release management
❌ Barriers to innovation and business agility

The Challenge: Outdated Applications, Growing Operational Risk

The bank’s critical systems were creating:

  • Release management delays
  • Compliance inconsistencies
  • Integration issues with modern platforms
  • Rising maintenance costs
  • Increased operational risk
  • Limited scalability
