C&N Online Banking System Requirements

Important notice regarding your Online Banking system requirements


C&N's Online Banking System will no longer support TLS 1.0 security protocol in order to align with industry best practices and ensure that your data continues to be highly secure.

What is TLS?

TLS stands for “Transport Layer Security.” It is a protocol that provides privacy and data integrity between two communicating applications. It’s the most widely deployed security protocol used today, and is used for web browsers and other applications that require data to be securely exchanged over a network.

When does this change take place?

On May 1st, we will begin to disable the TLS 1.0 encryption protocol, which may prevent those who still use it from using some or all of your online and mobile banking functionality. This means that you may need to upgrade your browsers to disable TLS 1.0 and use TLS 1.1 or higher, but this change will not affect you in any other way.

How do I know if I will be compatible?

You can test your TLS “score” by visiting this website, and you can see if your browser has already disabled TLS 1.0 by visiting this website.
