DOT E-Tickets via HaulHub

For those customers who need to send E-Tickets to their state DOT for certain jobs, Keystone uses a third-party service (HaulHub.) This service requires an increased level of data security that is only supported on modern versions of Windows. See the Keystone 5 section below for the minimum Windows versions supported.

Keystone 5 incorporates significant changes related to security and functionality. Many of these changes leverage improvements in Windows that simply did not exist in older Windows versions. Additionally, there have been many improvements in the database engine (InterBase) that provide higher performance and reliability.

Windows Versions

Keystone 5 requires a minimum of one of the following Windows versions:

(Server) Windows Server 2016 or higher
(Desktop) Windows 11 or higher

If you are running any versions of Windows prior to the above (on server and desktops) please ask your IT provider to coordinate Windows upgrades with us as soon as possible so that you can continue to receive updates to your Keystone software. To ensure a smooth upgrade process, we strongly recommend installing the most current version of Windows on a new server or virtual machine. This will allow any upgrade issues to be worked out without impacting your daily operations.

There are other reasons to keep your Windows versions up-to-date:

Microsoft provides regular security updates for current Windows versions to help protect your systems from ransomware/malware/virus attacks.
Keystone increasingly interfaces with third party applications using REST/JSON protocols that require higher levels of security than older Windows versions are capable of.
Keystone uses cloud-based services that also require these higher levels of security.

InterBase

In addition to upgrading older Windows versions, you may need to upgrade the database engine that Keystone requires to a newer version. Please contact support to determine whether this is necessary. If a database upgrade is required we will prepare a quote for you.
