Case Study: How We Eliminated Shadow AI Usage in 30 Days

Executive Summary

A $50B+ financial services company faced a widespread shadow AI problem, over 2,000 employees were using unauthorized AI tools on personal devices, risking customer data, compliance violations, and operational efficiency. Within 30 days, WeAreQuest eliminated shadow AI exposure, improved productivity by 31%, and delivered a 3,415% ROI.


The Crisis Call

"We have a problem."

That’s how the CISO of "Atlantic Financial" opened our call. His team had just discovered multiple customer PII entries in ChatGPT logs, from accounts they didn’t even know existed.

Despite a company-wide ban on external AI tools, employees had created risky workarounds to stay productive.

The Discovery:

  • 2,000+ employees using unauthorized AI tools

  • 47 confirmed data exposure incidents

  • 28% productivity decline in tech departments

  • Zero visibility into AI interactions

  • Compliance violations across multiple frameworks

The ban meant to protect the enterprise had created a bigger security nightmare.


Shadow AI: Hidden, Costly, Widespread

Our audit uncovered the true extent of the issue.

Usage Snapshot

  • 72% of employees (2,247/3,100) were using shadow AI tools

Top Workarounds:

  • Personal ChatGPT on work machines – 34%

  • Photographing documents with personal phones – 28%

  • Emailing files to personal inboxes – 23%

  • Using VPNs to bypass restrictions – 15%

Data at Risk:

  • Customer financial info: 89 incidents

  • Strategic documents: 156 incidents

  • Code/specs: 203 incidents

  • Legal documents: 67 incidents

Departmental Impact

  • Software Dev: 31% productivity decline

  • Legal & Compliance: 26%

  • Ops: 22%

  • Customer Service: 19%

The Real Risks

  1. No visibility or logging

  2. No control over data movement

  3. All the risk of AI none of the benefits

Employees needed AI. The ban wasn’t stopping usage, it was just making it dangerous.
