Clients will be able to run IBM's growing catalog of assistants and agents, based on IBM's Granite models, natively on z17 without taking on the added risk associated with moving data or sensitive business logic off platform. Together, these solutions are engineered to form an optimized stack, to enable clients to drive more productivity with security and scale.

Built for Resiliency: Security and Cyber Defense at the Core 

IBM z17 furthers the platform's history of strong security and resiliency capabilities. New developments in AI have enabled the deployment of added intelligence across this ever-growing area of importance for clients as new threats appear every day. This includes several new capabilities, including:

  • Secrets Management – Capabilities from HashiCorp, an IBM Company, announced in March are now available on IBM Z to help standardize secrets management across hybrid cloud. IBM Vault uses identity-based security to authenticate and authorize access to secrets, certificates, keys, tokens and other sensitive data. With the addition of IBM Vault, clients can have a single solution to help protect critical workloads by managing the entire secrets lifecycle across their full IT estate.
  • AI-powered Data Security – IBM intends to deliver new capabilities for discovering and classifying sensitive data on the platform. This would tap into Telum® II and utilize natural language processing so mission-critical data can be identified and protected. Additionally, our latest AI-driven security solution, IBM Threat Detection for z/OS, is designed to detect and identify potentially malicious anomalies that might be the result of a cyber-attack.
