The Challenge

The client, a Fortune 500 global investment bank, was operating with a legacy perimeter-based security model that had grown organically over decades. With increasing cyber threats targeting financial institutions and growing regulatory pressure, their existing security architecture was proving inadequate for modern threat landscapes.

The organization faced multiple critical challenges that threatened both operational efficiency and regulatory compliance, requiring a fundamental transformation of their security approach.

Legacy Security Architecture

20-year-old perimeter security model with over-privileged access, insufficient visibility into user activities, and inability to detect lateral movement within the network.

Increasing Security Incidents

Monthly security incidents averaging 150+ events, with 12% requiring significant investigation and remediation resources, impacting business operations.

Regulatory Compliance Risks

Auditor concerns about security controls effectiveness, potential regulatory fines, and inability to demonstrate adequate protection of customer financial data.

Operational Inefficiencies

Manual security processes consuming 40+ FTE hours weekly, delayed incident response averaging 8+ hours, and fragmented security tooling across departments.

Cloud Migration Barriers

Security concerns blocking cloud adoption initiatives, limiting business agility and competitive advantage in digital banking services.
