Data breaches in the United States have reached an alarming new milestone. According to IBM’s 2025 Cost of a Data Breach Report, the average cost of a data breach in the U.S. has surged to $10.22 million, marking an all-time high. This increase stands in stark contrast to the global average, which has decreased by 9% to $4.44 million.

Why U.S. Data Breach Costs Continue to Rise
IBM attributes the rising cost in the U.S. to a combination of stricter regulatory fines and increased detection and escalation expenses. As cyberattacks grow in sophistication, more resources are needed to identify, respond to, and contain threats. Regulatory scrutiny also plays a major role, with non-compliance leading to substantial financial penalties.
The Global Landscape: Faster Response = Lower Costs
Globally, organizations are seeing improved outcomes, largely thanks to AI and automation. The average time to detect and contain a breach dropped by 17 days last year, down to 241 days. This faster response saved companies an estimated $1.9 million on average. The key takeaway? Proactive technologies significantly reduce the cost and duration of cyber incidents.
The Hidden Costs: Disruption and Delayed Recovery
Beyond direct financial losses, IBM’s findings highlight the widespread operational impact of cyber breaches. Nearly every organization studied experienced some form of disruption, with most taking over 100 days to fully recover. Alarmingly, 65% of breached companies reported that they still hadn’t fully recovered, underscoring the long-term consequences that can be.
AI in Data Breach: The Next Frontier of Cyber Risk
While artificial intelligence (AI)-related breaches remain relatively rare, they are becoming more serious. IBM reported that 13% of surveyed organizations experienced a breach involving AI models or applications. Most of these were linked to supply chain vulnerabilities, compromised APIs, third-party apps, or plug-ins.
Even more concerning is that 97% of AI-related breaches occurred due to weak or nonexistent access controls. In other words, many businesses are integrating AI without putting basic security measures in place. Suja Viswesan, IBM’s VP of Security and Runtime Products, warned that AI is becoming a “high-value target” and that the lack of proper oversight is opening the door for malicious actors.
The Cost of Shadow AI
One particularly troubling trend identified in the report is the rise of “shadow AI”—AI systems deployed without organizational oversight or approval. These rogue tools contributed an additional $670,000 to the global average breach cost, often leading to the exposure of personal identifiable information (65%) and intellectual property (40%).
Shadow AI also complicates risk management, especially when sensitive data is stored across multiple environments. As IBM noted, “just one unmonitored AI system can lead to widespread exposure.”
