SilverSHielD is a SSH (SSH2) and SFTP server for Windows. Below you can read some of its features:
Additional security settings
Ability to set the maximum number of concurrent connections (Pro edition only)
Ability to force a delay upon new connection, for anti-hammering
Put the client IP in tarpit after a definable number of failed authentication attempts
Functions and subsystems
Secure Shell/Command (SSH2)
SFTP (Secure File Transfer)
Administration is performed though a modern Management Console, included in the download package, which establishes a secure channel with the SilverSHielD server and allows remote configuration of one or many servers
Unlike many other competing products, SilverSHielD isn't loaded with tons of (often useless) features; instead it's focused on simplicity and ease of use, and of course on security and reliability.
And it's free of charge if a single client connection at a time is sufficient for you. If you need to allow more than one client connection at a time, you can purchase the Pro edition. Anyway your free edition will never expire and all our free edition users are entitled to lifetime updates and upgrades.
