Patterns tell a story. After decades of casework, one thing becomes clear: fraud does not strike every industry equally. Some sectors call for a fraud investigation far more often than others, and the reasons are rarely random. Where money moves fast, oversight is thin, or trust is assumed rather than verified, fraud follows.
The numbers back this up. The Association of Certified Fraud Examiners (ACFE) estimates that a typical organization loses roughly 5% of its annual revenue to fraud, and its 2024 study of 1,921 real cases documented more than $3.1 billion in losses worldwide. On the consumer side, the Federal Trade Commission reported that people lost more than $12.5 billion to fraud in 2024, a 25% jump over the prior year, climbing again to a record of about $15.9 billion in 2025. When we look at which industries reach out to us most, those figures stop being abstract. They point directly at where risk concentrates and why certain organizations keep landing in the crosshairs.
Here is what the demand for a fraud investigation reveals about risk across the sectors that need it most.
Banking and Financial Services: Where the Money Lives
It is no surprise that financial institutions top the list. The ACFE’s 2024 data recorded more cases in banking and financial services than in any other category, with 305 documented cases. When your core business is moving and holding money, you become the natural target for both insider schemes and external attacks.
The risk drivers here are structural. High transaction volumes make anomalies easy to hide, complex products create room for manipulation, and employees often have direct access to accounts and payment systems. A single fraud investigation in this sector frequently uncovers layered schemes involving falsified records, unauthorized transfers, or collusion between staff and outside parties.
What this says about risk: proximity to money multiplies exposure. The closer employees sit to cash and payment controls, the more rigorous your segregation of duties and monitoring need to be.
Healthcare: Complexity Breeds Opportunity
Healthcare consistently ranks among the highest-demand sectors for investigative work, and it is one of the areas we handle directly through our healthcare fraud investigation practice. The ACFE documented 117 healthcare cases in its 2024 report, but the real story is the complexity that makes this industry so vulnerable.
Billing systems are dense, third-party payers add layers of separation, and the sheer volume of claims makes individual review nearly impossible. Common schemes include:
- Billing for services never rendered
- Upcoding to higher-reimbursement procedures
- Kickback arrangements between providers and suppliers
- Phantom patients and duplicate claims
What this says about risk: when the person paying the bill is not the person receiving the service, oversight breaks down. Healthcare’s payment structure practically invites a fraud investigation, which is exactly why proactive auditing matters so much in this space.
Government and Public Administration: Spending Under Pressure
Government entities accounted for 171 cases in the ACFE’s 2024 study, and public-sector work makes up a meaningful share of our own caseload. Procurement fraud, bribery, false invoicing, and contract misappropriation are recurring themes, and the stakes are high because the money at risk belongs to taxpayers.
Public spending moves through bidding processes, grants, and vendor relationships that can be gamed by insiders or contractors. The pressure to disburse funds quickly, especially during emergencies, often outruns the controls meant to protect them. Our work on government corruption cases shows how a single compromised approval chain can cascade into millions in losses.
What this says about risk: speed and volume without verification is a recipe for abuse. Independent oversight is not bureaucratic overhead; it is the safeguard that keeps public money honest.
Manufacturing and Corporate Enterprises: The Insider Problem
Manufacturing logged 175 cases in the 2024 ACFE data, with a median loss notably higher than many other sectors. Corporate environments in general, from mid-sized firms to large enterprises, generate steady demand for a fraud investigation because they combine valuable assets with layered management structures where accountability can blur.
This is the territory of embezzlement, asset misappropriation, and executive-level deception. In our own casework, patterns repeat: trusted employees exploiting weak controls over long periods. We documented this in our analysis of how long theft went undetected across 50 embezzlement cases, and again in the Jaragosky case, where $642K was stolen from a contractor. The common thread is time: the longer a scheme runs unnoticed, the larger the loss.
What this says about risk: internal trust without internal controls is fragile. The businesses that get burned are usually the ones that assumed “it could never happen here.”
What the Patterns Teach Every Organization
Across all these industries, the same risk factors surface again and again. The ACFE found that more than half of occupational frauds trace back to either a lack of internal controls or the override of existing ones. Tips remain the single most effective detection method, responsible for 43% of cases, roughly three times more than any other method. Organizations with anonymous reporting hotlines catch fraud faster and cheaper.
You do not have to be in a high-risk sector to act on these lessons. Practical steps any organization can implement now:
- Establish an anonymous reporting channel. Tips catch more fraud than audits, management review, and IT controls combined.
- Enforce segregation of duties. No single person should control a transaction from start to finish.
- Run surprise audits. Predictability is a fraudster’s friend; unpredictability is yours.
- Monitor behavioral red flags. Living beyond means and reluctance to share duties are recurring warning signs. Our breakdown of the red flags in almost every case we’ve worked covers these in detail.
- Use data analytics. Duplicate payments, unusual vendors, and off-pattern transactions surface fast when you know where to look, as our duplicate payment case demonstrated.
Conclusion: Risk Is a Pattern, Not a Surprise
The industries that hire us most are not unlucky. They are structurally exposed, and the demand for a fraud investigation in banking, healthcare, government, and corporate settings maps almost perfectly onto where money, complexity, and weak oversight intersect. The encouraging part is that these patterns are visible and manageable. Fraud thrives in the dark, but it leaves a trail every time.

Frequently Asked Questions
1. Which industry has the highest fraud risk?
Banking and financial services consistently record the most fraud cases, according to ACFE data, largely because employees work in close proximity to money and payment systems. Healthcare, government, and manufacturing also rank high due to complex billing, large spending flows, and layered corporate structures.
2. When should a business call in an outside fraud investigator?
Bring in an independent investigator when you notice unexplained financial discrepancies, receive a credible tip, or find that internal review has reached its limits. An outside fraud investigation adds objectivity and produces documentation designed to withstand legal and regulatory scrutiny, which internal teams may struggle to deliver alone.
3. How is occupational fraud most often detected?
Tips are by far the leading detection method, accounting for 43% of cases in the ACFE’s research. This is why organizations with anonymous reporting hotlines tend to catch fraud earlier and limit their losses.
4. What does a fraud investigation actually involve?
The work typically begins with initial intelligence such as tips or flagged transactions, moves into forensic analysis of records and digital trails, and ends with a clear, evidence-based report. The goal is to establish what happened, who was responsible, and how, in a format suitable for boards, regulators, or courts.
5. How much does occupational fraud cost organizations?
The ACFE estimates the typical organization loses about 5% of revenue to fraud each year, with a median loss per case that rose 24% between 2022 and 2024. Because much fraud goes undetected or unreported, these figures are considered conservative.
6. Can smaller businesses reduce fraud risk without a big budget?
Yes. Low-cost measures like an anonymous tip line, segregation of duties, and periodic surprise audits deliver outsized protection. Many devastating frauds in smaller organizations succeed simply because basic controls were missing, not because the scheme was sophisticated.
