since we deal with lots of different customers, and you want to be able to have the trust that no matter what operations you're doing, whatever transactions you have, that you can trust that we're managing your data and also your information. My name is Patricia Voigt, and I am the Chief Information Security Officer at Webster Bank. As the Chief Information Security Officer, I'm responsible for securing all of our assets within the organization. You're talking about all the data, all the systems, all the technology components that are involved in storing data, especially bank transactional data. We've been a Varonis customer for quite a long time. We're initially using it to help us with a challenge that we were having, which was really around visibility around some of our shared drive access. We had a lot of open access to different data sources that were created that may not be necessary to retain over the longer term. It is something that took us from having, say, over a million different files out there across our organization, shared in different types of formats, and being able to take that data and reduce it down to less than 1% of what we have that isn't secure data out there across our organization. We're taking steps into using AI across our environment, and we have gone with the co-pilot, Microsoft co-pilot platform. Varonis has helped us to be able to help manage that environment, including help provide that kind of monitoring and oversight of what our colleagues are trying to do so that we can help to kind of facilitate them from being able to kind of transform the way they're doing business, as well as to be able to keep that a secure process as we move forward. And Varonis is a package that works with a lot of the security solutions we already have in place that we consider the major partners that we have. And so having them in that mix really helps tie everything together easily and succinctly across our organization. ♪♪

TL;DR

  • Webster Bank reduced unsecured file exposure from over 1 million files to less than 1% using Varonis to gain visibility and control over shared drive access.
  • The bank uses Varonis to monitor and secure their Microsoft Copilot AI implementation, ensuring colleagues can innovate while maintaining security and compliance.
  • Varonis integrates with Webster's existing security partners to provide unified oversight across the organization's data security ecosystem.

Summary

Patricia Voigt, Chief Information Security Officer at Webster Bank, explains how Varonis helped the financial institution address critical data security challenges across millions of files. The bank faced significant exposure from overly permissive shared drive access, with more than a million files accessible across the organization without proper controls. By implementing Varonis, Webster Bank gained comprehensive visibility into data access patterns and systematically reduced unsecured file exposure to less than 1% of their total data footprint. The solution integrated seamlessly with Webster's existing security infrastructure while providing the monitoring capabilities needed to support their Microsoft Copilot AI adoption. Voigt emphasizes that in financial services, customer trust depends on demonstrating rigorous data management practices, and Varonis has become a central component in tying together their security ecosystem to protect sensitive banking and transactional data.
