Secure Shell (SSH) provides an open protocol for securing network communications which is less complex and expensive than hardware- based VPN solutions. Secure Shell client/server solutions provide command shell, file transfer, and data tunneling services for TCP/IP applications. SSH connections provide highly secure authentication, encryption, and data integrity to combat password theft and other security threats. VanDyke Software clients and servers are mature native Windows implementations that offer a range of SSH capabilities and are interoperable with SSH software on other platforms.
