Welcome back to Fraudology.
In this episode, I’m joined by someone I have been trying to bring back on the show for years, Holly Sandberg. Holly has led fraud operations, served on the Americas Advisory Board at MRC, and was the former Director of Trust and Safety at Reverb. So yes, when we talk about what AI can and cannot do in fraud, she is exactly the kind of person I want in that conversation.
We are in that very familiar moment where everyone is trying to decide whether AI is going to replace fraud teams, make fraud teams more efficient, or somehow solve all the problems that have been annoying us for the last decade. Right. Because apparently fraud strategy was just waiting for a chatbot.
Not quite.
This episode is really about human-in-the-loop fraud detection, and why the human part is not just a nice backup plan. It is the strategy. AI can help fraud teams move faster, summarize patterns, support investigations, and surface signals. But it does not replace domain expertise. It does not know what your fraud team knows. It does not understand your company’s risk tolerance, your customer base, your edge cases, your past attacks, or the proprietary signals your team has built over time.
That is where things get interesting.
Holly and I dig into why senior fraud leadership still matters in a world full of LLMs, why model drift is not something you can casually ignore, and why fraud prevention strategy has to include people who actually understand how fraud works in the real world. Not just in open-source data. Not just in a model output. In the actual messy environment where fraud operations happen every day.
What you’ll hear in this episode:
- Why Holly Sandberg believes senior fraud leadership cannot be replaced by LLMs
- How human-in-the-loop fraud detection strengthens AI fraud prevention
- Why domain expertise is not found in open-source data
- What fraud teams need to understand about AI hallucinations and model drift
- How fraud professionals can get involved in AI steering committees and cross-functional strategy
- Why the “bias toward certainty” in AI can create risk in fraud operations
- How to think about career resilience, layoffs, quiet rehiring, and proving value in a changing market
You should listen to this episode if you:
- Work in fraud operations and are trying to understand where AI actually fits
- Lead a fraud, trust and safety, risk, or payments team and need a grounded AI fraud prevention strategy
- Are worried about LLMs replacing human fraud expertise
- Want to better understand model drift, AI hallucinations, and fraud model oversight
- Are looking for practical ways to show leadership why your fraud expertise still matters

Episode notes & key takeaways:
Why human-in-the-loop fraud detection matters
Human-in-the-loop fraud detection is not about keeping a person around as a formality. It is about making sure someone with fraud expertise is still interpreting what the tools are producing.
AI can identify patterns. It can summarize activity. It can help teams move through data faster.
But fraud teams still have to ask the harder questions.
Does this signal actually matter? Is this customer behavior normal for this business? Is the model catching something useful, or is it reacting to noise? Is the pattern new, or have we seen this playbook before?
That is the difference between using AI as a tool and letting AI quietly become the decision-maker.
- Human oversight helps teams interpret fraud signals in context
- Fraud prevention strategy still depends on judgment, not just automation· AI can support investigations, but it cannot own accountability
- Human expertise in fraud detection helps teams avoid confident but wrong decisions
Why AI hallucinations create fraud risk
AI hallucinations are not just a chatbot problem.
In fraud operations, a hallucination can turn into bad guidance, a weak investigation summary, a misleading risk interpretation, or a decision that sounds right because the output is written confidently.
And that is the part fraud teams should care about.
A lot of fraud knowledge is not public. It lives inside internal case notes, customer patterns, chargeback data, merchant behavior, trust and safety workflows, and years of hands-on experience. So when LLMs in fraud prevention are asked to reason from incomplete or open-source information, they may not have the context that matters most.
And if they do not have it, they may fill in the blank.
That usually does not end well.
- AI hallucinations can create false confidence in fraud decisions
- LLMs may miss proprietary fraud patterns that are not available in public data
- Fraud teams need to validate AI-generated summaries, recommendations, and risk interpretations
- Domain expertise helps teams know when an answer does not line up with reality
Why domain expertise is still a fraud control
Domain expertise is not just “nice to have.” It is one of the strongest controls a fraud team has.
Experienced fraud leaders know how criminals adapt. They know how payment flows shift. They know when a metric looks stable but the underlying behavior is starting to change. They know when a control is technically working but no longer solving the real problem.
That kind of pattern recognition does not come from a generic model output.
It comes from doing the work.
This is why fraud prevention leadership still matters in an AI-driven environment. Senior fraud professionals are not just reviewing queues. They are making judgment calls about risk appetite, customer friction, escalation, tooling, vendor performance, and where the next exposure might show up.
- Domain expertise helps fraud teams recognize emerging behavior patterns
- Fraud operations leadership connects data to business context
- Model drift requires people who understand what “normal” should look like
- Fraud model oversight works best when experienced operators are involved early
Why fraud teams need a seat in AI strategy
If your company is building an AI roadmap, creating an AI steering committee, or deciding where automation belongs, fraud needs to be part of that conversation.
Not after launch.
Before.
Fraud teams are already seeing how generative AI fraud changes the scale and quality of attacks. Better phishing. Better fake identities. Better social engineering. Faster testing. More convincing stories.
So when companies start using AI internally, fraud professionals bring a perspective other teams may not have. They understand where automation helps. They also understand where automation creates a new blind spot.
- AI risk management should include fraud, trust and safety, legal, product, and engineering
- Fraud teams can identify where automation may create exposure
- Cross-functional AI strategy helps prevent tools from being deployed without proper oversight· Fraud prevention strategy should shape how AI is used in customer and transaction workflows
Why fraud professionals need to show future value
This episode also gets into something very real for fraud professionals right now.
AI is changing the career conversation.
It is not enough to say, “Here is what I have done.” That matters, of course. But the stronger position is to explain what your expertise helps the business do next.
Can you help evaluate AI fraud prevention tools? Can you spot model drift before it turns into losses? Can you translate fraud patterns into business risk? Can you help product, compliance, legal, and engineering understand where fraud exposure actually lives?
That is the value.
Because fraud expertise is not just casework. It is institutional knowledge, operational judgment, and pattern recognition. And companies still need that, even when they are trying very hard to believe a tool can replace it.
Final takeaway
AI is going to keep changing fraud operations. That part is clear.
But the strongest fraud programs are not going to be the ones that remove people from the process and hope the model figures it out. They are going to be the ones that use AI with the right humans in the loop.
People who know the business.People who know the fraud patterns.People who know when something does not feel right.People who can challenge the output instead of just accepting it.
Because in fraud, moving faster is only useful if you are still moving in the right direction.
