A significant new concern highlighted in the report is the AI Oversight Gap, where organizations are rapidly adopting AI without implementing proper security and governance policies.
For the first time in five years, global data breach costs have decreased, according to IBM’s 2024 Cost of a Data Breach report. The average cost of a data breach dropped slightly from $4.45 million in 2023 to $4.41 million in 2024. This decline is largely attributed to the growing adoption of artificial intelligence (AI), automation, and advanced security tools that help organizations detect and respond to breaches faster.
The report highlights that companies leveraging AI and automated security systems significantly reduced breach lifecycle times. Organizations with extensive AI-based defenses detected and contained breaches 108 days faster on average than those without such tools. These faster response times translate into millions in savings. In fact, businesses with fully deployed security AI and automation saved up to $1.8 million compared to those without these technologies.
AI and machine learning are being used to identify anomalies, automate threat detection, and streamline incident response. Automated systems now play a key role in mitigating human error—the leading cause of breaches—while reducing dependency on manual monitoring.
Despite the encouraging trend, the report notes that the overall risk landscape remains volatile. Cyberattacks are becoming more complex, with ransomware and phishing still among the top attack vectors. Healthcare continues to experience the highest breach costs across industries, averaging $11 million per incident.
While data breach expenses remain high, the integration of AI and automation into cybersecurity strategies is proving effective in reversing the cost trend. Organizations that invest in these technologies are better equipped to minimize financial and reputational damage from breaches.
The study also stresses that proactive cybersecurity investment is crucial. Companies that regularly test their incident response plans and adopt a zero-trust security approach experienced lower breach costs.
