Security Notice

Effective December 11, 2017, CharterNet Online Banking will require TLS 1.2 or higher to align with industry best practices for security and data integrity.  To avoid any disruption to your Online Banking access you may need to upgrade your web browser or operating system to support TLS 1.2.

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. TLS ensures that a connection to a remote endpoint is the intended endpoint through encryption and endpoint identity verification. The versions of TLS, to date, are TLS 1.0, 1.1 and 1.2.
