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

Table of contents

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

The Real Risks
No visibility or logging
No control over data movement
All the risk of AI none of the benefits
Employees needed AI. The ban wasn’t stopping usage, it was just making it dangerous.
