The Challenge

The company is one of the world’s finest banks (among the Fortune 500 companies) situated on the west coast of the United States. Its core activities include retail banking, investment banking and wealth management.

The company’s current IT infrastructure lacked innovation and was posing severe security threats, impacting its business excellence and growth. Some of the key challenges faced by the client include:

Legacy IT cost controls and rigid practices slowed innovation and agility.

High business complexity exposed gaps in the IT support model.

Reactive IT management addressed issues only after outages, causing productivity loss.

Absence of a proactive IT strategy led to recurring issues and downtime risks

Weak network security failed to support growing business needs.

Limited technology consulting hindered alignment between IT and business goals.

Overreliance on basic managed services reduced focus on long-term digital transformation.

Our Solution

To sustain its competitive edge in the market, while ensuring prompt banking services to thousands of its customers, the client needed a solution that can streamline and strengthen its current IT infrastructure and network security. After exploring a couple of vendors, the client finally partnered with ACI Infotech to take this initiative forward.

As part of this engagement, ACI Infotech engaged key stakeholders to understand the client’s business goals, technology needs, and strategic priorities while assessing existing risks and recurring vulnerabilities. ACI’s evaluation revealed a reactive IT model dependent on temporary issues and cost-centric staffing, which affected stability and enhanced security exposure.

By implementing a comprehensive root cause analysis, ACI identified network instability as the primary issue and designed a targeted transformation roadmap focused on performance, security, and cost efficiency. It deployed cloud-managed switches and firewalls, migrated email from an on-premises Exchange system to Microsoft Office 365, and took up the responsibility for first-line support and infrastructure maintenance.

This proactive approach delivered a more stable, secure, and scalable IT environment that resulted in minimized long-term costs, thereby helping the client to focus on core business objectives.
