Data Fellows Ltd. Media Release For immediate release 28 April 1998 DATA FELLOWS STRIKES A MAJOR DEAL A Prominent Scandinavian Telephone Operator Invests in Data Security Helsinki, Finland, April 28, 1998 -- Data Fellows, a leading provider of Internet security solutions, has made a deal with the largest private telephone company in Finland. Helsinki Telephone Corporation has bought F-Secure SSH to enhance the security of its Kolumbus Internet services over public networks. Kolumbus is one of the largest providers of commercial Internet services in Finland. "Data security is a highly important consideration for us," says Mr. Vesa Perttunen, Development Manager from Helsinki Telephone Corporation, Kolumbus Services. "We evaluated the data security products available on the market, and F-Secure SSH was the best we could find. We particularly appreciated the fact that the source code is available to us." Says Mr. Tatu Vehmas, Sales Manager, from Data Fellows: "F-Secure SSH leaves no room for security compromises. Furthermore, it is the only sensible tool for secure remote systems administration currently available on the market. We are pleased that Kolumbus Services has chosen our unique F-Secure SSH package." The F-Secure SSH Package F-Secure SSH products are based on the SSH security protocol. The SSH protocol is an application level protocol with strong public key authentication and 128-bit encryption. It guarantees the simultaneous authentication of both ends of the connection, the secrecy of the transmitted information, and the integrity of the transmitted data. F-Secure SSH Terminal provides the user with secure login connections over untrusted networks. It acts as a replacement for the telnet protocol. F-Secure SSH Terminal fully supports VT100 terminal emulation. F-Secure Tunnel creates a local proxy server for remote TCP/IP services. The service can be one of the Internet protocols, pop, smtp (used by e-mail software), http (used by Web browsers), etc., or almost any other TCP/IP based service. The local proxy server listens for a socket on the desired port and forwards the request and data over the secure channel. It then instructs the F-Secure SSH Server to make the connection to the specified service on the remote machine. In addition to secure terminal connections and TCP/IP connection forwarding, F-Secure SSH Server provides tools to replace existing rsh, rlogin, rdist, and telnet protocols. These tools enable administrators to carry out all remote systems administration tasks over secure connections.
