Why Mainframe Security Falls Outside Zero Trust Strategies Disconnected identity controls, overlooked integration paths, and siloed teams can leave mainframes outside Zero Trust strategies. Closing the blind spots starts with shared accountability. Mainframe Zero...
Compare how z/OS and VSEⁿ handle access control, threat detection, and cyber recovery – and what those differences mean for your workloads. A fair comparison of z/OS vs. VSEⁿ security starts with business requirements, operational risks, and recovery needs. ...
The mainframe hasn’t changed. The economics of attacking it have. Encryption, authentication, and access controls deserve another look. In early April 2026, Anthropic published a research preview of Claude Mythos, a general-purpose model whose security capabilities...
Cybercriminals collaborate. Shouldn't mainframe security professionals do the same? At SHARE 2026, I had the opportunity to sit down with Linda McGrath, Sales Director at Vertali, and Andrew Penlington, Channel Partner Development Manager, to discuss Mainframe Shield,...

For years I have told mainframe security newcomers the same thing: If you want to learn how to attack and defend a system, you need to use that system. Unfortunately, z/OS is not something you spin up on a laptop over lunch or throw into your home lab. Mainframe...
Mainframe modernization is often discussed in broad strategic terms, but for the teams responsible for keeping core systems running, the challenge is much more practical: How do you make change faster, safer, and more repeatable without disrupting critical...
In an era defined by AI hype and cloud-first declarations, the mainframe environment, in contrast, appears quiet and refined. Organizations running IBM Z continue to anchor revenue, enforce governance, and modernize on their own timetable. Nothing is happening...
Mainframes hold the heart of the most critical business processes in finance, healthcare, and government. Yet many security programmes still draw a neat line around them, treating z/OS as out of scope for red teaming, scenarios, and cyber risk quantification. This...
Open Mainframe Project Security Concerns I was chatting with a mainframer buddy the other day, and he expressed some concerns about the overall code security of the Open Mainframe Project (OMP), particularly around member vetting. So, I spent a bit of time digging...
