Incident Cost by Industry: Which Sectors Pay the Most
Incident cost varies dramatically by industry. Healthcare remains the costliest sector at $6.64M per breach (IBM CODB 2026), about a third above the $4.99M global average, even after a 10.5% year-over-year decline. Finance is second at $6.29M, with industrial and technology tied at $5.50M. Manufacturing's downtime cost per hour exceeds most other sectors because physical production stops when IT systems fail. The healthcare, finance, technology, and industrial figures reflect IBM CODB 2026; energy, pharmaceuticals, education, retail, and public-sector figures below are the 2025 edition, where the 2026 sector figure is not yet separately reported.
Industry Comparison Master Table
| Industry | Avg Breach Cost | Ransomware Risk | Downtime Cost | Primary Regulatory Exposure | Primary Threat |
|---|---|---|---|---|---|
| Healthcare | $6.64M | High | $540K/hr | HIPAA | Ransomware + data theft |
| Finance | $6.29M | Very High | $1.2-4M/hr | GLBA/SEC/FFIEC | BEC + ransomware |
| Industrial / Manufacturing | $5.50M | Very High | $260K-$2.3M/hr | Export control | OT ransomware |
| Technology | $5.50M | High | $1M+/hr | Reputational | Supply chain + insider |
| Energy / Utilities | $4.83M | High | Critical infrastructure | CISA/NERC CIP | OT/ICS targeting |

Healthcare: $6.64M Average Breach Cost
Healthcare has been the most expensive sector for data breach cost for well over a decade per IBM, and it held that position in the 2026 report even as its average fell 10.5% to $6.64M. The figure reflects the convergence of several cost multipliers unique to healthcare: HIPAA Tier 4 notification requirements (strict timelines and individual notifications for each affected patient), the high per-record value of health data, the patient safety dimension that justifies faster ransom payment to restore clinical systems, and the operational impact of taking EHR systems offline during remediation.
The Change Healthcare ransomware attack of February 2024 is the largest healthcare cyber incident in US history, with UnitedHealth Group reporting $2.87B in direct costs including ransom payment, remediation, and claims backlog. The incident disrupted prescription processing across the US for weeks and forced thousands of pharmacies to operate manually. Healthcare ransomware attacks have increased 400% in incidents involving demands exceeding $200,000 since 2020.
Finance: $6.29M and the Fastest-Growing Regulatory Exposure
Financial services is the most regulated and most targeted sector. The $6.29M average breach cost (IBM CODB 2026) is the second-highest of any industry, behind only healthcare. Finance faces mandatory reporting to multiple regulators (SEC, FFIEC, state banking departments, Federal Reserve) with strict timelines. Business email compromise (BEC) is the top financial threat by volume, though ransomware is highest by cost.
The SEC's 2023 cybersecurity disclosure rules now require material incident disclosure within 4 business days, creating rapid market reaction pressure that amplifies reputational cost. Financial services firms also face the highest cyber insurance premiums as a result of their threat profile, averaging $200K-$1M/yr for enterprise policies.
Manufacturing: Downtime Over Breach
Manufacturing's breach cost ($5.50M, IBM CODB 2026) is above average, but the more distinctive cost is downtime: $260,000/hr for average manufacturing, up to $2.3M/hr for automotive assembly lines (Siemens True Cost of Downtime 2024). OT/ICS ransomware incidents that affect production lines create a cost pressure toward rapid ransom payment that other sectors do not face. The Clorox ransomware attack of 2023 cost $356M in total impact including 13 weeks of manufacturing disruption. Multiple auto manufacturers have experienced multi-day production stoppages due to IT/OT ransomware.
Retail: PCI Exposure and Seasonal Risk
Retail breach costs ($3.54M average) edged up year-over-year. PCI DSS creates the primary regulatory exposure: a card data breach during non-compliance triggers both card brand fines and mandatory forensic investigation costs. The seasonal concentration of retail revenue creates asymmetric downtime cost: a 2-hour outage during Black Friday peak can equal a full week's regular revenue. Point-of-sale system compromises remain the top breach vector for large retailers.
