Bastion SFTP Suite
Both ends of the SFTP conversation.
Bastion SftpClient and Bastion SftpServer, written to talk to each other. The same ideas carry the same names in both — learn one and you know the other.
What is in the Bastion SFTP Suite
2 libraries, one purchase, one invoice. Each is a complete product in its own right — follow the links for the full detail.
Bastion SftpClient
SFTP from your own code: ten lines to a working transfer, post-quantum key exchange, recursive runs and a client that defends itself against a hostile server.
$399 per developer on its own
Bastion SftpServer
An SFTP server inside your application: twenty-six events, two-factor login, a brute-force defender and a hard directory jail.
$449 per developer on its own
What you save
Single-developer OEM prices.
| Library | 1 developer, OEM |
|---|---|
| Bastion SftpClient | $399 |
| Bastion SftpServer | $449 |
| Bought separately | $848 |
| Bastion SFTP Suite | $699 — you save $149 |
Build the client and the server your partners connect to from the same library family, tested against each other and against OpenSSH, PuTTY, Paramiko and SSH.NET.

Try it properly first
A thirty-day evaluation of every library in the pack. Nothing removed and no limits — you evaluate exactly what you would buy.
Because the trial is the whole product, sales are final, and accepting the terms and conditions of sale is part of completing a purchase. The one exception: report a serious defect and, if we cannot fix it and release an update within thirty days, we refund you in full.
