Who is Responsible for this change?

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.

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

It’s important for ATM owners to understand that Best Products and CDS are not responsible for this change. Other processors have announced the same information.

Which ATMs Are Affected?

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

If your ATMs use atm.columbusdata.net and ports 6963, 6964, or 6965 you need to update.

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. 

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.
