Case Study: Leading Banking & Finance Institute achieves zero‑downtime SFTP encryption for mainframe file transfers with SSH.COM's Tectia SSH Server for IBM z/OS

Leading Banking & Finance Institute - Customer Case Study

Leading Banking & Finance Institute, a major Australian banking and financial services provider with 10k+ employees and 15+ LPARs, faced the need to replace legacy FTP with secure, encrypted transfers on its IBM mainframe to protect sensitive financial transactions, support huge daily file volumes with zero downtime, and meet strict regulatory requirements. To address this, the customer selected SSH.COM and its Tectia SSH Server for IBM z/OS solution.

SSH.COM deployed Tectia SSH Server for IBM z/OS, using FIPS-certified cryptography and PKI/X.509 to automatically encrypt data-in-transit (including user IDs and passwords), with optional IBM Crypto Express Card offload to reduce CPU usage and accelerate cryptographic operations. The installation required no system shutdown, completed in weeks, cut firewall complexity (one SFTP port vs. two for FTP), supported compliance (PCI DSS, SOX, HIPAA, etc.), and delivered seamless, reliable SFTP operations with long-term infrastructure and cost benefits.
