Top 10 Industries Where Small Businesses Face the Most Cyber Risk

-

Not all small businesses face the same level of cyber risk.

Some industries are hit harder because they handle sensitive data. Some are targeted because they move money quickly. Others are exposed because they rely on vendors, web portals, email-heavy workflows, or distributed operations that create more ways in.

There is not one single public report that publishes a perfect SMB-only “top 10 industries by exact number of cyber attacks” table. But when you combine the latest verified small-business claims data, breach-pattern data, and sector-specific incident trends, a clear picture emerges.

Certain industries appear again and again.

Here is a practical, data-backed ranking of the industries where small businesses appear to face the most cyber risk.

1. Professional Services

Professional services consistently sits at the top of SME cyber claims data. This category includes law firms, accounting and tax firms, consulting firms, and real estate-related professional services.

In NetDiligence’s SME cyber claims data, professional services accounted for 20% of all claims and 23% of total incident cost above $1,000.

That makes sense. These businesses handle sensitive client information, email-heavy workflows, contracts, invoices, trust-based communications, and often high-value financial interactions. That combination makes them attractive targets for ransomware, business email compromise, and fraud.

2. Healthcare

Healthcare is one of the most consistently targeted sectors because it combines sensitive personal data, time-sensitive operations, payment workflows, and high legal and notification exposure.

NetDiligence’s SME claims data says healthcare accounted for 11% of all claims and 12% of total incident cost. The same report also notes that healthcare is one of the sectors attackers remain especially focused on when data loss is involved.

For small healthcare organizations, one breach can quickly expand into patient-data exposure, operational disruption, legal review, and notification costs.

3. Manufacturing

Manufacturing may not always get the same attention as healthcare or finance, but it remains one of the more costly SME cyber sectors.

NetDiligence reports that manufacturing accounted for 9% of all SME claims and 11% of total incident cost. The top causes of loss were ransomware, business email compromise, and wire transfer fraud.

Manufacturers often depend on uptime, suppliers, project files, distributed facilities, email approvals, and sometimes older or specialized systems. That combination creates both operational and financial exposure when something goes wrong.

4. Financial Services

Financial services is exactly where attackers expect to find money movement, sensitive account data, and workflows that rely on trust and speed.

NetDiligence’s SME claims data shows financial services accounted for 7% of all claims and 7% of total incident cost. The leading causes were business email compromise, ransomware, and hacker activity.

For smaller firms in this sector, even one compromised inbox, fraudulent transfer request, or access-control failure can create outsized damage.

5. Retail

Retail remains highly exposed because it sits at the intersection of payments, customer data, web platforms, and frontline operations.

NetDiligence reports that retail accounted for 6% of all SME claims and 7% of total incident cost. Retail businesses also routinely face risks tied to ransomware, business email compromise, and broader hacker activity.

For SMB retailers, cyber risk does not only mean stolen data. It can also mean payment disruption, downtime, customer friction, and direct revenue loss.

6. Information and Technology Services

Information and technology-oriented firms are especially exposed because they often operate online-first, depend on web applications, manage customer or client systems, and rely heavily on credentials and remote access.

Verizon’s breach data shows that the Information sector is one of the top three industries most affected by Basic Web Application Attacks, accounting for 14% of that pattern.

Small technology firms, SaaS providers, managed service providers, web businesses, and digital service companies all face a version of this problem: if your business runs through internet-facing systems, those systems become a bigger part of the attack surface.

7. Legal, Accounting, and Advisory Firms

This group sits inside the broader professional-services category, but it deserves separate attention because the combination of trust, sensitive documents, payment instructions, privileged information, and client deadlines creates a particularly rich target set.

Coalition’s sector materials for legal organizations specifically call out business email compromise as a frequent cause of claims, and many of the same dynamics apply to accounting, tax, and advisory firms.

These firms are attractive because attackers know clients are used to urgent requests, confidential communication, and high-trust financial or legal workflows.

8. Real Estate and Property Services

Real estate and property-related businesses are another sector where cyber risk is amplified by trust, transaction timing, and high-value financial workflows.

Real estate appears inside the broader professional-services category in NetDiligence’s SME claims study, and Coalition’s real-estate industry materials highlight real cases involving business email compromise, vendor fraud, and ransomware pressure.

For smaller property managers, brokerages, and real-estate firms, a single compromised inbox or payment instruction can quickly become a fraud event with customer-trust consequences.

9. Construction and Field-Service Businesses

Construction and field-service businesses are increasingly exposed because they rely heavily on email, mobile devices, vendor coordination, project files, subcontractor communication, and distributed operations.

Coalition’s industry guidance for construction says the average cost of a cyber claim for construction businesses is about $110,000, the average ransomware loss is about $264,000, and about 80% of attacks originate from the email inbox.

That makes construction one of the clearest examples of how operational businesses can still face concentrated cyber risk even if they do not think of themselves as “digital-first.”

10. Restaurants, Hospitality, and Food Service

Accommodation, food service, and restaurant businesses remain important cyber targets because they depend on payments, point-of-sale activity, reservations, customer data, and busy operations with little tolerance for downtime.

Verizon continues to treat Accommodation and Food Services as a distinct breach-reporting vertical, and real-world breach case studies in restaurant environments show how quietly payment-card and operational compromise can spread before the business realizes the scope of the problem.

For a small business in this category, the impact of a cyber incident is often immediate: revenue disruption, customer-trust damage, and potential payment-data fallout.

What this ranking really means

This list is not saying other industries are safe. Almost any small business can be breached.

What it does show is that some sectors combine more of the ingredients attackers like:

  • sensitive data
  • money movement
  • high-trust communications
  • web-facing systems
  • vendor dependency
  • distributed operations
  • limited time for verification

The more of those traits your business has, the more likely cyber risk becomes a real operational issue rather than a background concern.

What the common pattern looks like

Even though the industries differ, the core drivers repeat:

  • stolen credentials and weak authentication
  • business email compromise and funds transfer fraud
  • ransomware and system intrusion
  • web application and remote-access exposure
  • third-party or vendor access risk
  • human error inside fast-moving workflows

That is why the same industries keep surfacing in breach and claims data year after year.

What small businesses should do now

If your business operates in one of these sectors, the takeaway is not panic. It is prioritization.

Start with the controls most likely to change your risk:

  • Use MFA everywhere that matters, especially email, finance, admin, and remote access
  • Review vendor and third-party access regularly
  • Tighten payment and account-change verification
  • Patch internet-facing systems faster
  • Reduce stale accounts and unnecessary privileges
  • Train staff on phishing, impersonation, and unusual requests
  • Improve visibility into what is exposed, connected, and weakly controlled

Small businesses do not need enterprise complexity. But they do need to know when their industry puts them closer to the front of the target list.

Final thought

Some industries attract more cyber risk because they handle more money, more trust, more data, or more operational complexity. Others are hit more often because attackers know that smaller firms in those sectors are busy, exposed, and easier to pressure.

The point is not to obsess over rankings. The point is to understand where your business sits in the risk landscape — and act before attackers make that decision for you.

Your Password Policy Isn't Protecting You. Your Employees' Habits Are.

Thought Leadership Credential Risk May 2026  ·  8 min read 94% of leaked passwords are reused or duplicated. Employees reuse the same password an average of 13 times. And by 2026, nearly half of all successful cyberattacks on SMBs will originate from credential reuse. Most businesses have a password policy. Almost none have visibility into whether anyone follows it. Think about the password you use for your personal email. Now think about whether any of your employees use that same password — or a variation of it — to log into your business systems. You don't know. And that uncertainty is the problem. In 2024, a security researcher analyzed 19.03 billion leaked passwords from breach databases and found that only 6% were unique. The other 94% had been used before — on another account, at another company, in another breach. Every one of those reused credentials is a master key that attackers test systematically...

Thought Leadership Incident Response May 2026  ·  8 min read In 2025, the fastest attacks moved from stolen credential to complete data exfiltration in 72 minutes — 4x faster than the year before. Most businesses discover breaches 292 days later. Here is exactly what an attacker does in that window — and what it means for your business before anyone has noticed. At 11:43pm on a Tuesday, an automated tool tests a stolen credential against your email platform. It matches. A session token is issued. In the next 72 minutes — while you sleep, while your team sleeps, while your IT provider sleeps — a sequence of events unfolds that will take your business an average of 292 days to discover. This is not a hypothetical. The 2026 Unit 42 Global Incident Response Report — Palo Alto Networks' annual analysis drawn from hundreds of real-world breach investigations — found that the fastest 25% of attacks in 2025 reached full da...

Thought Leadership Insider Threat May 2026  ·  8 min read Most small businesses invest in perimeter security and assume the threat is outside. The data tells a different story. The most financially damaging cyber incidents don't break through your defenses — they walk past them, using legitimate access your own employees already have. In May 2025, Coinbase discovered that cyber attackers had recruited a group of their own customer support agents — employees with legitimate system access — and bribed them to hand over customer data. The attackers then used that data to impersonate Coinbase representatives, manipulating customers into sending them cryptocurrency. When the attackers contacted Coinbase demanding a $20 million ransom, the company refused to pay. The total cost — including customer reimbursements, security upgrades, and regulatory response — ran significantly higher. Coinbase isn't a naive startup. They're one of...
