The average cost of a data breach in the United States reached an all time high of 10.22 million dollars, about 2.3 times the global average, according to IBM Cost of a Data Breach research. The figure stands out even as the global average cost fell to 4.44 million dollars, a 9 percent decline and the first drop in five years, driven largely by faster breach containment.

Artificial intelligence cut both ways in the data. Organizations that used AI security tools extensively saved about 1.9 million dollars per breach and detected incidents roughly 80 days faster, the primary reason costs declined globally. At the same time, unmanaged AI created new exposure.

The governance gaps were striking. Among breached organizations that experienced an AI related security incident, 97 percent lacked proper AI access controls and 63 percent had no AI governance policy in place. Unsanctioned use of internet based AI tools, known as shadow AI, added an extra 670,000 dollars to the average breach cost and was a factor in 20 percent of breaches, with 65 percent of those shadow AI incidents exposing personally identifiable information.

Industry differences persisted. Healthcare remained the most expensive sector at 7.42 million dollars per breach, its fifteenth consecutive year at the top. The data describes a security environment where AI powered defenses are lowering costs for prepared organizations while ungoverned AI adoption raises the price of the breaches that do occur.
