SDS VFTP-SSH Collaboration is a secure file transfer and remote access solution developed by Software Diversified Services (SDS) for IBM z/OS mainframe environments. It combines SFTP (SSH File Transfer Protocol) and SSH capabilities to provide encrypted file transfer and terminal access on the mainframe platform. The product enables organizations to replace legacy, unsecured FTP and Telnet sessions with encrypted SSH-based alternatives, helping to protect data in transit on mainframe systems. It is designed for enterprises that require secure, standards-based file transfer and remote login capabilities within their z/OS infrastructure. Key capabilities include SSH-based file transfers (SFTP), secure shell terminal sessions, and support for industry-standard cryptographic protocols. The product is positioned as a mainframe-native security solution that supports compliance with data protection and security policies by encrypting file transfers and remote sessions. SDS VFTP-SSH Collaboration is a commercial product targeted at mainframe shops needing to secure file transfer workflows and remote access without moving away from z/OS infrastructure. It supports standard SSH/SFTP client connectivity, allowing mainframe systems to interoperate with a wide variety of SSH-compatible endpoints across the enterprise network.
