SSH COMMUNICATIONS SECURITY CONTINUES TO ENHANCE ITS FILE TRANSFER SOLUTION FOR IBM MAINFRAMES BASED ON CUSTOMER DEMAND


SSH Tectia Server 5.4 for IBM z/OS Adds Additional Support for MVS Dataset      
Types, IBM z/OS Systems Management Features and Enhanced Cross-Platform         
Interoperability Features Within and Between Windows, Unix, Linux, and IBM      
Mainframe Environments                                                          

HELSINKI, FINLAND and WELLESLEY, Mass. - April 18, 2007 - SSH Communications    
Security (HEX:SSH1V), a world-leading provider of enterprise security solutions 
and end-to-end communications security, today announced that SSH Tectia Server  
5.4 for IBM z/OS is generally available with new usability features and         
increased integration into the IBM mainframe environment.                       

SSH Tectia Server for IBM z/OS is a cost-effective file transfer solution       
supporting direct MVS (Multiple Virtual Storage) file system access and hardware
acceleration for secure cross-platform file transfers and secure TN3270         
connections.                                                                    

SSH Tectia products are increasingly being deployed for use in internal networks
with thousands of Unix, Linux and Windows computers.  Responding to increased   
customer demand, SSH has now introduced a set of new features that makes it     
easier and faster to introduce secure file transfers for IBM mainframes in a    
heterogeneous computing environment. Some of these include a Key Distribution   
Utility for automated distribution and setup of server host keys and user public
keys, which makes the management of keys considerably less time consuming and   
error prone. Also included is support for the OpenSSH key format, enabling easy 
integration of security between the IBM mainframe and Linux or Unix systems that
use OpenSSH.  This new version also supports GDG data sets, giving users direct 
access to MVS files without unnecessary staging or without intermediary file    
conversion.                                                                     

With the introduction of new usability features it now easier than ever for     
users to securely transfer files to and from the mainframe. Using SSH Tectia's  
graphical user interface or command line interface, users can access mainframe  
data without having to be mainframe experts.   Also included is the FTP         
compatibility feature, which eases the transition to SFTP. Finally, the new     
version introduces improved logging and auditing of file transfers due to its   
support of IBM's Systems Management Facility (SMF) allowing companies to meet   
corporate auditing policies.                                                    
                                                                                
“During the past years our customers have come to realize that data transfers   
over their networks are increasingly vulnerable and subject to misuse” said Arto
Vainio, CEO of SSH Communications Security Corp. “Most companies have for years 
transmitted passwords and data files as clear text, not just in their internal  
networks but also with external customers and partners. While this may have been
acceptable in the past, it is no longer a viable solution. SSH Tectia, with its 
IBM mainframe and extensive platform support enables organizations to easily and
cost-effectively secure their file transfers without expensive development or   
integration projects.”
