VShell® 4.4 Server

Protect access to your mission-critical servers with:

  • Multi-protocol secure file transfer
  • Secure remote access and administration using SSH2
  • Reliability and robustness: "set it and forget it"

File transfer options include:

  • A robust SFTP server offering a wide variety of encryption algorithms plus support for FTPS and FTP
  • An HTTPS file transfer server allowing browser-based or scripted uploads and downloads (available with the HTTPS Enterprise edition for Windows)
  • The power to lock down users and groups to desired locations in the file system using virtual roots

Perform secure remote access and administration with:

  • Command shell access
  • Remote execution of commands and applications
  • Port forwarding (data tunneling)
  • Fine Grain Access Control

    Grant access to VShell services by authorized users or groups. On an individual or group basis, allow or deny access to VShell services such as shell, SFTP, and port forwarding.

  • Lock Down Users with Virtual Roots

    Virtual root directories let you assign different root directory access points to users or groups. In Windows, assignment can be based on access control lists (ACLs).

  • Automate Processes with Triggers

    Configurable trigger conditions allow automated responses to server events such as login, logout, upload, and download, as well as file/folder create, delete, and rename.

  • Flexible Logging Options

    Selected server messages may be logged in the VShell log file, sent to the Windows system log or a remote syslog/syslog-ng server. Message groups include errors, warnings, informational, connection, authentication, SFTP, port forward, debug, LSA, and FTPS. The W3C extended log file format option allows the use of third-party log tools to analyze VShell activity.

  • See Active Connections with VShell Monitor

    VShell Monitor is a real-time connection monitoring tool that allows an administrator to view active connections to the VShell server. VShell Monitor can be set to start on administrator logon and provides easy access to the VShell Control Panel and Help.

Whether you need file transfer or a wider range of remote access services, it takes reliable, configurable network access software to master evolving security threats and a rapidly changing business environment.

"I downloaded VShell and set it up within a day. It's been very reliable and I haven't had a single bit of down time.  We leveraged the trigger feature to automatically upload files in real time into our production system."

—Jeramie Mercker, Software Architect, Georgia Municipal Assn.

Key Benefits

Provide strong, multi-protocol security for data in transit. The Secure Shell (SSH2) protocol delivers proven, open-standard authentication, encryption, and data integrity that let you provide a wide range of services to your organization with confidence.

FTPS increases your protocol choices (including FTP for support of legacy devices).

The Enterprise edition with HTTPS for Windows allows users to transfer files easily using a web browser.

Control user access to features and files. VShell gives you extensive controls to manage privileges for shell, file transfer, and other services. Examples include access control lists and virtual root directories.

Set up and configure easily. VShell installs and runs right "out of the box". Windows setup and configuration is made easy by the graphical control panel.

Monitor and log events with automation support. VShell triggers help you track and respond to events like failed logon attempts and uploaded files. Event logging supports security monitoring and regulatory compliance.

Use connection-based licensing to your advantage. VShell Administrator, Workgroup, and Enterprise editions allow cost-effective licensing from one user to thousands.

The Enterprise edition with HTTPS for Windows reduces administrative overhead by eliminating the need to purchase, install, and maintain additional software for file transfer.

Our support program includes expert technical support and regular maintenance releases.

New in VShell Server 4.4


VShell 4.4 for Windows introduces a new Enterprise edition with HTTPS support, providing an easy-to-use, browser-based file transfer solution for your staff, customers, and external partners.

SFTP virtual roots allow you to map folders from multiple SFTP servers to a single VShell server, and an improved virtual root user interface makes configuration faster.

An enhanced deny host feature improves the ability to ward off brute force attacks.

Now on all platforms, an internal user database eliminates the need for system user accounts for VShell end users and simplifies migrations.

Here are some of the new features in VShell 4.4:

New edition: Enterprise with HTTPS for Windows
A new enterprise-level edition of VShell with HTTPS allows your staff, customers, and partners to transfer files easily using a web browser, eliminating the need for end-user training. Streamline the administrative cost of secure file transfer – no client software is needed and there are no browser plugins to install. Users connect via HTTPS to view folder contents, upload and download files, and more. Automated file transfers can be scheduled using HTTPS command-line tools such as cURL.

SFTP virtual roots (Windows)
SFTP virtual roots allow you to map folders from multiple SFTP servers to a single VShell server or leverage an external SFTP server by seamlessly transferring end-user connections from VShell to the target server. After authenticating the connections, VShell transparently transfers file operations to a separate SFTP server. Files are uploaded and downloaded without ever being written to the VShell server's disk, assisting with standards compliance and reducing the disk space required by the VShell host machine.

Improved virtual roots user interface (Windows)
The Virtual Roots category of the VShell Control Panel has been completely redesigned to accelerate virtual root configuration and improve usability. See at a glance which users and groups have access to your file system, which folders they can see, and what file operation permissions they have. Edit properties in place without opening a dialog.

Internal user database (UNIX/Linux/Mac)
Eliminate the need to create system accounts for end users when accounts are only needed for VShell access. Simplify future migrations by letting VShell automatically include your users and groups when you move the VShell configuration to a new server.

Now on the UNIX/Linux and Mac versions in addition to Windows.

Specify deny hosts failure time (Windows - SSH2 SFTP and FTPS)
Ward off brute force attacks by specifying the amount of time in which a certain number of authentication failures from a particular IP address will be tolerated. Any further authentication attempts by that IP address will be immediately disconnected. Optionally, re-allow connection attempts from a previously denied IP address after a certain amount of time.

Support for encrypt-then-MAC (EtM) algorithms
Support has been added for encrypt-then-MAC (EtM) algorithms, including SHA2 and UMAC.

Allow or deny specific SFTP commands
Choose whether to allow or deny specific SFTP commands on a per-user or per-group basis, including SETSTAT, FSETSTAT, RMDIR, REMOVE, RENAME, and LINK.
