BACKGROUND

Strengthening identity security during system consolidation

A large commercial banking organization was undergoing a strategic acquisition that required consolidating applications, systems, and user access across the enterprise. As part of this transition, the organization needed to ensure that account access remained secure, well-governed, and aligned to evolving operational needs. 

THE OPPORTUNITY

The organization had an opportunity to strengthen identity governance by improving visibility, control, and consistency across user accounts during system integration. 

THE CHALLENGE

The organization needed to validate and secure more than 7,000 user accounts across disparate systems while minimizing the risk of credential-based threats during the merger. 

THE CHALLENGE

Managing account risk across fragmented systems

Following the acquisition, the bank faced increased complexity across its identity and access landscape. Systems and applications from both organizations needed to be aligned, creating challenges in maintaining visibility into user access and permissions.

Unmanaged and overprivileged accounts increased the risk of credential-based breaches, particularly during a period of heightened activity and system change. The organization needed to quickly identify, categorize, and remediate account risks while maintaining continuity across critical operations.

 

THE SOLUTION

Delivering structured account validation to improve identity governance

TSG executed a comprehensive account validation program to assess and remediate user access across the enterprise. The team worked closely with stakeholders to verify, categorize, and prioritize accounts, ensuring alignment with security and operational requirements.

Through disciplined execution, TSG identified and remediated unadministered and overprivileged accounts while improving overall visibility into identity governance. The approach strengthened access controls and supported a more consistent and scalable model for managing user accounts.
