Challenge: Overshared Legacy Data Threatened Secure Copilot Rollout

Barry-Wehmiller, a global industrial and packaging automation and consulting services leader with 150 operating locations internationally, saw huge potential in Microsoft Copilot to unlock productivity. But as the organization looked to expand its rollout, a key issue stood in the way: data oversharing.

With many terabytes of SharePoint,OneDrive, and Teams content accumulated over several years, the security and IT teams did not know how to assess or quantify the risk of deploying Copilot across the broader organization, especially when it came to ensuring sensitive data didn’t fall into the wrong hands.

Initially, the team considered manually reviewing sites that looked like they might contain sensitive content, but that approach quickly proved unrealistic and unscalable given the sheer volume and complexity of the data environment.

Solution: Opsin Helped Prioritize the Risk and Made It Actionable

High-Impact OversharingFlagged in Days

Barry-Wehmiller partnered with Opsin Security to identify the real risk. Instead of sifting through terabytes of content, Opsin delivered a focused view of what was actually exposed and sensitive — prioritizing issues involving PII, financials, and business-confidential IP, which mattered most from a business impact standpoint. This gave the security team clarity, and made it easy to align leadership on the next steps.

Targeted Remediation with Real Business Impact

Opsin didn’t just surface the risk. It helped Barry-Wehmiller quickly remediate the risk. With clear instructions, site-level context, and easy delegation to business units, the team remediated over 70% of oversharing issues identified in the risk assessment within weeks.

From a high-risk score, where over 70% of prompts referenced overshared data, the team brought it down to less than 20% of prompts exposing sensitive data.

Remediation covered everything from public Microsoft Teams sites to broadly exposed OneDrive folders and widely shared files in private SharePoint sites without overloading IT.

Ongoing Impact: Continuous Monitoring and Confidence to Scale Copilot

Today, Opsin helps Barry-Wehmiller proactively monitor Microsoft 365 for oversharing and automate remediation, saving the security and IT teams hundreds of hours of manual effort.

Most importantly, it gave the CISO and executive team the confidence to expandCopilot usage across the enterprise.

Results: Oversharing Controlled, AI Rollout Accelerated

Looking Ahead: A Model for Responsible AI Rollouts

Barry-Wehmiller didn’t just solve a problem. They built a framework for governing AI securely at scale. With Opsin, the company now has the visibility, control, and oversight needed to support Copilot and future AI tools with confidence.

In addition, Opsin now helpsBarry-Wehmiller enforce AI usage policies and ensure ongoing protection against oversharing or misuse as Microsoft Copilot is broadly adopted.
