Client Technical Services is updating email address used for customer communications

On 7/02/2024, we are upgrading servers to enhance the performance and security of the Client Technical Services website (CTS Portal). As a result, we are changing the email address we use to communicate with our customers to [email protected]. Please configure your email accounts to receive emails from the new email address and ensure the email address is added to your email program’s safe sender list.

New look for Client Technical Services website

TransUnion has updated the look of the Client Technical Services (CTS Portal) website. You will notice a slight difference in the look and feel of the website, but the organization and functionality of the website is the same. This update will allow us to improve the functionality in the future and better improve your experience.

TransUnion has disabled TLS 1.1 and now requires stronger cipher access

TransUnion is preparing to update the Client Technical Services Portal (CTS Portal) to accept only traffic using version 1.2 of TLS (Transport Layer Security). TLS 1.1 will no longer be enabled. Browsers using TLS 1.1 will no longer be able to access the CTS Portal. This change will allow TransUnion to leverage newer versions of TLS to increase the security of our customer connections. See General Announcement #188 for additional information.

Notice: HTTP GET method will be disabled in TransUnion Net Access (TUNA)

As part of ongoing security enhancements, TransUnion will no longer support the HTTP GET method. TransUnion’s target for blocking all HTTP GET requests, including Production and UAT/Test, is currently set for August 10, 2020. As an alternative, customers can use HTTP POST. This method is used to send data to a server to create and update a resource. Data sent to the server using HTTP POST is stored in the request body of the HTTP request and is more secure than the GET method.

The change to disable the GET method is currently targeted for the following dates:

UAT/Test: July 15, 2020

Production: August 10, 2020

See General Announcement #182 for additional information.

Increase to TransUnion Net Access (TUNA) Availability

Reminder to all TUNA customers who blacklist outbound traffic: you will need to whitelist the IP address range listed below to leverage TransUnion's secondary TUNA platform, which will enhance its current High Availability even further, as well as "future-proof" for upcoming TransUnion products.

IP address range: 66.175.240.0/20
