Extend privacy and security across your hybrid cloud with the new IBM z15

Open architectures drive innovation, but sharing data across ecosystems can be a risky business: 60 percent of companies experienced a data breach caused by a third party.

The new IBM Z® system provides the highest level of data privacy, security and resiliency for your mission-critical applications and extends it across your hybrid multicloud environment.

IBM z14™

The z14 family now includes a dual-frame and single-frame model. Both are made for trusted digital experiences with the highest security, scalability and reliability.

IBM z13®

This earlier generation dual frame offers 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 offers many of the capabilities of the z13 in a smaller footprint. Until z14 arrived, it was the best entry-price mainframe for secure cloud.

Looking to modernize?

82 percent of organizations plan to increase or maintain enterprise data server usage over the next two years. Mainframe modernization may seem like an unsexy challenge, but it could be critical to your business objectives.
