If you’re running FTP on z/OS in 2025, you are facing a growing security and compliance problem. We know, FTP has been a reliable tool for decades. It’s simple, it works, and everyone knows how to use it. But that convenience comes with serious risks that can no longer be ignored.
The FTP Security Problem
FTP transmits everything in plaing text, passwords, usernames, and your data. Anyone with network access can see it all. No encryption. No data integrity checks. No security.
For z/OS shops handling regulated data, this creates immediate compliance issues:
- PCI DSS requires encryption for cardholder data
- HIPAA mandates protection for health information in transit
- SOX demands data integrity controls
Recent research shows 83% of organizations reported insider threats in 2024. Even your internal network is not as safe as you think.
Why Migration Seems So Hard
We’ve talked to hundreds of z/OS teams, and we hear the same concerns:
“FTP is embedded in thousands of our batch jobs.”
“We don’t even know where all our FTP transfers are.”
“Rewriting all that JCL would take years.”
“We can’t afford to disrupt our batch windows.”
These are legitimate concerns. Traditional migration approaches are disruptive, time-consuming, and risky.
There’s a Better Way
Modern migration technology has changed the game. Using a SOCKS proxy architecture on z/OS, you can:
- Migrate without rewriting JCL – Transparent FTP-to-SFTP conversion means batch jobs continue using FTP syntax while actual transmissions are encrypted
- Move at your own pace – Migrate specific jobs, users, or partners incrementally rather than all-or-nothing cutover
- Leverage existing OpenSSH – Use the encryption software already included with z/OS
- Gain complete visibility – Know exactly what FTP transfers are running before you start
Our customers report 60-70% faster migration timelines compared to traditional JCL rewrite approaches.
