Customer Story

Commercial and Retail Bank

Large commercial and retail bank leverages Microsoft Defender to enhance security with help from Hitachi Solutions.

Facing security risks associated with access management resulting from a complex network of multiple endors, tools, and environments, this large commercial and retail bank had no effective way to manage administrative access, exposing them to potential identity and data breaches. To address these critical issues, the bank’s leadership partnered with Hitachi Solutions to enhance their security posture and implement a comprehensive identity management strategy.

Challenge

With great data comes great responsibility.

In our interconnected, digital world, customer data is extremely valuable and simultaneously, there’s a tremendous responsibility to maintain security and privacy. But maintaining that security is only becoming more and more difficult amid increased cybersecurity threats.

Banks have one of the highest levels of security among critical U.S. industries and some of the most stringent regulatory requirements, according to the American Bankers Association. Regardless, there are
thousands of security breaches annually at financial institutions globally and in 2024, the average cost of a data breach in the financial industry, commonly caused by outdated data management systems, was $6.08 million, according to a report by Statista.

In addition to this bank’s complex network of Active Directory systems aging with time, they were also becoming increasingly expensive to maintain. Initially, their security focus was limited to on-premises
systems, with no effective way to manage administrative access. This limitation posed a substantial risk of identity and data breaches, and their slow internal processes made it difficult to implement necessary security measures promptly.

Solution

To ensure compliance with industry standards and to safeguard their business against threats, the bank turned to Hitachi Solutions for help. Hitachi Solutions worked closely with the bank’s leadership to develop and implement a tailored security and identity management solution and roadmap.

A key element of their solution portfolio was Microsoft Defender, a comprehensive suite of security solutions designed to provide advanced threat protection and security management across various platforms and environments.

The bank understood that within their industry, where data breaches can lead to significant financial loss and reputational damage, the value of Microsoft Defender could not be overstated. The platform’s advanced threat protection ensures potential vulnerabilities are swiftly identified and addressed, while supporting stringent compliance. By leveraging Defender, they didn’t just invest in a solution, they protected the sanctity of their customer relationships by laying a bedrock of security.
