The security of mission-critical data and transaction processing is now primarily based on legacy systems. This emphasis on protecting this data has led organizations to invest in specialized security controls. The potential for billions of daily transactions and decades-worth of proprietary code adds to the significance of protecting these systems. In addition, there has been a substantial amount of media coverage related to high-profile breaches. Therefore, organizations have increased the difficulty of governing their systems by implementing more stringent compliance regulations. The mainframe security market has transitioned from simple access control to integrated identity, encryption, and anomaly detection solutions over the last several years.
Another prominent global mainframe security market trend affecting the market growth is the convergence of regulatory pressures and hybrid-cloud modernization initiatives. As organizations are moving workloads from on-premises to hybrid environments, they are also exposing their mainframe systems to new threats. Therefore, organizations are increasing their investments in identity federation, privileged access management, and real-time analytics to help them comply with regulatory requirements and maintain operational continuity.
For example, banks that have implemented tokenization of payment rails have reduced the time required to commit fraud while also complying with the various Payment Services Directive 2 (PSD2) and Payment Card Industry (PCI) regulations; similarly, insurers that have implemented immutable audit trails have greatly simplified investigations.
How is AI Enhancing Threat Detection in the Mainframe Security Market?
Mainframe security is seeing improvements in threat detection through the combination of behavioral analytics to detect deviations in the way transactions are processed, anomaly detection and contextual telemetry to identify deviations from established patterns and behaviors. Automated log synthesis and user and entity behavior analytics are additional examples of how AI can enhance threat detection in mainframe security environments. In addition, vendors are integrating AI-based solutions into observability and response tools, which result in improved accuracy for alerts being generated and quicker timelines for investigative root cause analysis. Demand is also driven by the need to protect critical workloads (mission-critical workloads) without impacting availability.
Examples of these AI-based solutions include automated triage of anomalies, adaptive scoring for threats and guided response to make detection supportable for groups tasked with maintaining and operating mainframe systems. IBM introduced z17 on April 2025, which has built-in AI capabilities that enhance anomaly detection by reducing latency between inferring and accessing the data and minimizes the friction associated with operating the mainframe system as a whole. Thereby facilitating wider adoption and utilization of AI-enabled solutions within the realm of mainframe security.
