This Is an Industry-Wide Update, Not a CDS/ Best Products Specific Issue

It’s important for ATM operators to understand that Best Products and CDS are not responsible for this change. For one, other processors have announced the same information. Officially, Certificate Authorities (CAs), (the organizations responsible for issuing and managing digital security certificates), are updating their certificate infrastructure to meet evolving industry requirements.

Major technology companies, including Google, Apple, Microsoft, and Mozilla, have been driving changes to publicly trusted certificate systems.

According to DigiCert, one of the world’s leading certificate authorities, these developments include moving away from older certificate structures toward newer, dedicated security systems.

The CA/Browser Forum also maintains industry standards governing publicly trusted digital certificates.

Which ATMs Are Affected?

All ATMs that communicate over the locations internet will need their software updated, the host IP and port updated. 

This is any ATM using atm.columbusdata.net using ports 6963, 6964, or 6965.

If you use a wireless DPL modem, you are excluded from this, as DPL provides its own secure connection. 

If your ATMs process through another company, we recommend contacting your processor to determine whether similar certificate or connectivity updates are required. As of 11/9/2026 we are aware of other processors who are requiring this as well with the same deadline. 

What Happens If You Don’t Update?

CDS has warned that ATMs not updated by this date may experience connectivity problems or transaction processing interruptions. For ATM operators, that could mean downtime, lost surcharge revenue, and unnecessary service calls.
