Extending the Security Stack: Red Teaming, Scenarios, Risks, and Reality
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...
The Open Mainframe Project Has a Trust Problem — And the Mainframe Can’t Afford It
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...

Why It’s Finally Time to Retire Your TN3270 Emulator
For decades, TN3270 terminal emulators have been a staple for accessing mission-critical mainframe applications. However, as cyber threats evolve and legacy systems strain under new compliance demands, it is becoming increasingly clear that traditional...
Why Human Error is the Mainframe’s Biggest Risk
Mainframes have always had a bit of a superhero reputation: rock-solid, ultra-secure, and always up. They’ve powered banks, airlines, and governments for decades without so much as blinking. But I want to share an uncomfortable truth: even the most secure systems in...
