What's New in VersaLex v5.6

What's new in release 5.6

Cleo VersaLex v5.6 is available to all Cleo LexiCom, Cleo VLTrader, and Cleo Harmony customers under current support and is built into all new sales of Cleo software. This new release will provide even greater enterprise functionality within Cleo's family of ecosystem integration solutions.

New Cleo Portal features

Cleo Portal and Unify in Portal supports simple ad-hoc data movement between end users. New features were added to Cleo Portal in version 5.6 to streamline sharing and user management. Sharing features have been expanded to include a replacement for the retired Outlook Connector using anonymous links. Users now also have the capability to move, copy, and rename files in Portal. User management enhancements include shared SAML/Local login, two-factor authentication, and expiration dates for access to certain items.

New Connectors

New connectors have been added in version 5.6, including:

  • Azure Blob: Connect with Microsoft's Azure Blob storage.
  • GCP Storage: Connect with Google Cloud Platform's file storage containers.
  • Router: Route files based on file names and content.

Refreshed Host Tree

The web admin user interface has undergone a transformation to improve usability and responsiveness as well as decrease required resource overhead. In version 5.6, the Host Tree in the web UI is refreshed with a new aesthetic and new options. Users now have the ability to search within hosts, including an advanced search. The Local Listener has been moved out of the Host Tree and can be found in the Administration tile.

Framework enhancements

There have been several enhancements to the framework of the VersaLex product family, including security and performance enhancements. See for more information.

What's new in release 5.5

Cleo VersaLex v5.5 is available to all Cleo LexiCom, Cleo VLTrader, and Cleo Harmony customers under current support and is built into all new sales of Cleo software. This new release will provide even greater enterprise functionality within Cleo's trusted, managed file transfer software.

Ad-hoc file sharing for Cleo Portal

Increasingly, there is a need for end users to be consumers or producers of data movement orchestrations. In an effort to facilitate simpler and ad-hoc file sharing, Cleo Portal now supports sharing files and folders between end users through a separately licensable set of functionality called Unify in Portal. The Cleo Portal UI now includes up to three spaces for sharing - Home, Connections, and Shared with me

  • Users with the Cleo Unify privilege enabled at the host level can initiate sharing from their Home space.
  • Administrator (VLNavigator) users can also initiate sharing from the Connections space.
  • Files and folders that have been shared with other users appear in those users' Shared with me spaces.

Public REST API Expansion

Since their introduction in version 5.4, the Cleo Harmony public REST APIs have enabled users to configure and manage the product in a “lights out” manner. To provide additional flexibility in operating the Cleo Harmony installation, new REST API endpoints for provisioning users and managing nodes have been introduced. In addition, several existing endpoints have been further improved and expanded. Beyond the updates to the endpoints themselves, both OAuth and Basic authentication is now supported by the REST APIs. Support for Cross-Origin Resource Sharing (CORS) is supported in version 5.5. For more detailed information visit the updated developer.cleo.com.

New Web Admin User Interface

Beginning with this release, an updated user interface for the web admin is introduced. The new user interface is designed to improve not just usability of existing functions, but also improve the responsiveness of the user interface and decrease the required resource overhead for logged in users. In this release, the Event Log, Transfers, and Scheduler interfaces have been significantly improved. Additional areas of the user interface will be released in phases in future updates and releases.

What's new in release 5.4.1

Cleo VersaLex v5.4.1 is available to all Cleo LexiCom, Cleo VLTrader, and Cleo Harmony customers under current support and is built into all new sales of Cleo software. This new release will provide even greater enterprise functionality within Cleo's trusted, managed file transfer software.

Real-time Integration with Cleo Clarify and Cleo EEI

You can integrate Cleo Harmony (data movement) and Cleo Clarify and Cleo EEI (data transformation) to seamlessly hand-off between your applications. Any data from your trading partner can be passed through the Cleo Integration Suite (CIS) without the need to dispatch files or use custom programming.

New Cleo Dashboards

Cleo Dashboards offer a single source for viewing end-to-end data transactions in real-time – where it came from, where it is going, and its status. With out-of-the-box functionality to monitor and look up transactions within the Cleo Cloud Integration Suite (CIS), you get a consolidated view of communications and translation processes. In addition, you can control access to Cleo Dashboards, allowing non-technical users to view them.

Cloud and Big Data Connectors

Cleo Harmony now includes several new connectors for integrating with cloud- and big data-based entities to drive your business intelligence and analytics tools.

The HDFS connector enables interaction with HDFS stores for stand-alone, fault-tolerant storage or for purposes of analysis inside Hadoop.

The Amazon S3 connector enables out-of-the-box connectivity to Amazon S3 buckets.

Cleo Portal Self Registration

End users can invite others to register into Cleo Portal. Invitees are immediately added to the Cleo Harmony and Cleo VLTrader applications as users, but are left in a pending status until they self register. The Cleo Portal administrator can control which users are allowed to send out invitations as well as the permissions granted to newly added users.

What's new in release 5.4


A robust set of REST APIs is available within Cleo Harmony or Cleo VLTrader. You can use these APIs to access functionality ranging from configuring certificates to resending transfers.

Samba (SMB) host

For Cleo Harmony and Cleo VLTrader, host connection templates now include a generic SMB host connection. You can use an SMB host instead of the Windows/Unix Folders feature to enable access to a privileged share. It provides the following advantages:

You can configure an SMB host instance as the source or destination of other host transfers by using a URI reference (for example, smb:alias). Cross-host access rules are enforced so that you can restrict SMB share use to a subset of host connections depending on the relative positioning within the host tree folders. You can associate transfer logging through an SMB URI with the referencing host, which allows sends and receives through LCOPY commands to be "first-class citizens" in the transfer report.

Standalone Actions

Standalone JavaScript actions are not tied to a specific host or user. Instead, they exist beside, not within, hosts or users. Standalone actions are available only in Cleo Harmony.

You can use them for any of a number of purposes, including:

  • Incoming file filter
  • Log listener
  • Scheduled or event triggered tasks

A standalone action is allowed to access in-scope hosts and their incoming payload using new methods within the ISessionScript class.

A host and its payload is considered in-scope when it is in the same host tree folder (or within a nested folder) as the standalone action.

Antivirus Scan

A canned standalone action specifically for antivirus (AV) scanning is included with Cleo Harmony. If the AV scan action is activated, it will run at VersaLex startup and register an incoming file filter. Each incoming file that is in-scope is then scanned while it is being received and written. If the scan fails, the incoming file is removed and the file transfer fails, alerting the sending client that the file was not received.

A file is considered in-scope when it is in the same host tree folder (or within a nested folder) as the AV scan standalone action.

AV scanning uses the ICAP protocol to stream content from VersaLex to the AV server. A Generic ICAP host connection is also now included and would need to be activated and configured as part of VersaLex antivirus setup.

Protocol Security

Added TLS elliptical curve (ECDH) algorithms to the list of supported SSL/TLS cipher suites.

For the SFTP client, added capability to retrieve the host key using the Set Key button on the new host-level SSH FTP tab. The host key is used to verify subsequent connections are to the same server.

Added support for the SFTP diffie-hellman-group-exchange-sha256 key exchange algorithm.

For the WebSphere MQ client, added support for AES ciphers when using a secure connection.

Cleo Portal

Single Sign On (SAML)

Cleo Portal now supports the Security Assertion Markup Language (SAML) for purposes of web browser single sign on (SSO) and single logout (SLO). Within the SAML protocol, VersaLex is the service provider (SP) and supports interfacing with a single identity provider (IDP). LDAP must be used for user provisioning in conjunction with SAML.

Folder Maintenance

Previously users were able to upload, download, and delete files, but only had access to the inbox, outbox, and other folders allocated to them by their administrator. Now, users can create and delete their own folders.

Deep Links

Cleo Portal now supports deep linking to files and folders. That is, if a user has a link to the full path of a folder in Cleo Portal, rather than being sent to their Home view when they log in, they are sent directly into that folder. If they have the link to the full path of a file, they are sent into the folder that contains that file and a download starts immediately.

Folder-level Download

Cleo Portal now allows you to download an entire folder at a time as a .zip file.

Password Reset

With release 5.4, Cleo Portal supports two different ways for users to reset their passwords:

1. If a user forgets their password, they can click a link that will email them a randomly generated token that will send them to a password reset page. This will only work if the administrator has set up an email address for the user.

2. Users can reset their password from within Cleo Portal. If they click on the profile icon at the top right, a drop down menu with a Password option appears. Selecting the Password option displays a dialog box where they can reset their password.


You can configure Cleo Portal to lock out users after a number of unsuccessful login attempts you specify. When locked out, the user receives an email informing them of the lockout, provided an email address has been set up for the locked user. If the user resets their password, the lockout status is cleared, and the user can log in again.


In addition to the logos on the log in page and at the top left of the application, you can now customize the top banner color.

Cleo Unify

Multi-file download

With version 5.4, you can select multiple files and download at the same time as a zip file.

Software updates are sent to Cleo customers directly through the software and are included with current support. For more information on release features, please contact Cleo Support at 866.444.2536 (U.S.), +1 815 282 7894 (International) or support@cleo.com.
