TransUnion Net Access (TUNA): System Update - TLS 1.0 Disablement

TransUnion will be delaying the TLS 1.0 disablement originally scheduled this weekend, targeting October 29, 2017 as the new disablement date. We are doing so to better ensure that customers who access TransUnion via TransUnion Net Access (TUNA) are prepared for this change. Please be advised that as of the target date, TLS 1.0 will no longer be enabled for TUNA and it is strongly recommended that you upgrade to TLS 1.1 or TLS 1.2 as soon as possible, if you have not already completed this upgrade. For additional information, see General Announcement #157.

For more information about TUNA, see the TransUnion Net Access Resources page.
