Healthcare Data Breach Costs Drop, but U.S. Breaches Hit Record High in 2025
IBM’s 2025 Cost of a Data Breach Report reveals a mixed landscape for cybersecurity costs, with global averages declining for the first time in five years while U.S. breaches reach unprecedented levels. The study, based on data from 600 organizations across 16 countries and 17 industries, found that the global average cost of a data breach fell to $4.44 million, down from previous years. However, U.S. breaches surged to a record $10.22 million, a 9.2% increase from 2024, driven by higher regulatory fines and escalation costs.
Healthcare remained the most expensive industry for breaches, though costs dropped significantly $7.42 million on average, down $2.35 million year-over-year. Despite the decline, healthcare breaches still took the longest to detect and contain (279 days), five weeks longer than the global average of 241 days, a nine-year low.
Key Trends and Findings:
- Initial Access Vectors: Phishing (16%) overtook stolen credentials (10%) as the top attack method, with supply chain compromise (15%) ranking second.
- Ransomware: While attacks persist, fewer organizations paid ransoms 63% refused in 2025, up from 59% in 2024. Ransom demands averaged $5.08 million, but law enforcement involvement (now at 40%, down from 52%) reduced breach costs by $1 million when utilized.
- Operational Impact: Nearly all breached organizations faced disruptions, with most taking over 100 days to recover. Nearly half (49%) planned to offset costs by raising prices, with a third considering increases of 15% or more.
- Cost Drivers: Detection and escalation ($1.47 million), lost business ($1.38 million), and post-breach response ($1.2 million) remained the largest expense categories, though all saw slight declines.
- Mitigation Factors: DevSecOps (-$227K), AI/ML-driven insights (-$223K), and security analytics (-$212K) were the most effective at reducing costs. Conversely, supply chain breaches (+$227K), security complexity (+$207K), and shadow IT (+$200K) unauthorized software or devices drove costs higher. Organizations with high shadow IT levels faced $670K more in breach expenses.
- AI Risks: AI adoption outpaced governance, with 97% of breached organizations lacking proper AI access controls. 13% of organizations reported AI-related security incidents, while 16% of breaches involved attacker-used AI, primarily for phishing (37%) and deepfakes (35%).
- Investment Shifts: Only 49% of organizations plan to increase cybersecurity spending in the next year, down from 66% in 2024, with less than half prioritizing AI-driven solutions.
The report underscores persistent vulnerabilities in healthcare, the financial toll of delayed breach responses, and the growing risks of ungoverned AI and shadow IT in enterprise environments.
