We were concerned that Copilot could surface overshared data. Opsin made it manageable by enabling us to focus on the sensitive data that really mattered.

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.

“We had many terabytes of overshared data, and it wasn’t clear how to solve this problem rapidly.”
Roftiel Constantine, Global CISO, Barry-Wehmiller

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 Oversharing Flagged 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.

“Within 3 days, they produced an actionable list of 50 findings: overshared SharePoint sites, OneDrive folders, Teams conversations. It was not just actionable ─ it was manageable.

Opsin’s approach made it easy for me to sell the proof of concept to the IT leadership team.”
Roftiel Constantine, Global CISO, Barry-Wehmiller

➡️ 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.

“We didn’t have to deal with all overshared data ─ just the overshared data that really mattered.”
Roftiel Constantine, Global CISO, Barry-Wehmiller

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.

“Thanks to Opsin’s initial risk assessment and their continuous monitoring of files introduced into our M365 environment, it gave me the confidence to recommend that we move forward and expand our Copilot evaluation.

It gave not just me, but also my company, the confidence that we’re doing this in a very risk-aware and risk-minimization manner.”
