TLS 1.2 Update

On April 23rd, 2018, the bank will be disabling the Transport Layer Security (TLS) protocol 1.0 and 1.1 on our web applications. In short, please update your Operating System and\or Internet Browser to its latest version to access these applications without issue. 

Transport Layer Security (TLS) is a protocol that ensures that a connection to a remote endpoint is securely encrypted in order to provide privacy and data integrity. Cornerstone Bank web applications and application programming interface (API) connections use TLS as a key component of their security. TLS 1.2 is the most current version and is considered to be the most secure. TLS 1.0 and 1.1 are earlier, now less secure versions. DO NOT DISABLE TLS 1.0 OR 1.1. 

As we enhance our security to align with industry requirements, you will need to verify if your operating systems (OS)  or browsers support TLS 1.2 and upgrade if necessary. If you do not have a compatible OS version or browser after we disable the old versions, you will get a connection warning and\or error when attempting to access our online banking applications. Instructions for enabling TLS 1.2 are below.

How to enable TLS 1.2 in most Internet Explorer Versions:

 In the Tools menu, which is displayed by clicking on the gear icon near the top-right corner of an Internet Explorer 10 window, select the "Internet options" menu item, as depicted below: 

 
 
 
 
In the Internet Options window that appears, click on the Advanced tab at the top of the window. Scroll down to the end of the list and click in the square check boxes next to "Use TLS 1.1" and "Use TLS 1.2" if they don't already have a check mark in them. For additional security, click in the square check box next to "Use SSL 3.0" if it has a check mark in it to remove the check mark. When complete, the screen should resemble the following, where "Use TLS 1.1" and "Use TLS 1.2" both have check marks in the check boxes next to them while "Use SSL 2.0", "Use SSL 3.0", and "Use TLS 1.0" do not have check marks in the check boxes next to them. Press the OK button to save this change.
