The most trusted hardware platform

To compete, enterprises need to be trusted. To be trusted you need to provide the best possible security and resiliency. IBM Z offers pervasive encryption with millisecond response times and is designed for DevOps innovation, a stronger cloud, real-time insights and secure blockchain transactions.

IBM z14

The z14 family includes a dual-frame and new single-frame model and are made for trusted digital experiences – more security, real-time insights, and able to instantly scale.

IBM z13

This earlier generation dual frame offered best-in-class security, real-time insights, high performance, and the ability to scale. It was the best mainframe available until the z14.

IBM z13s

This single frame offered many of the capabilities of the z13 in a small footprint. It was the mainframe for secure cloud and real-time analytics – at an entry price.
