PCI Security and Browser Support

Last Updated: Jan 06, 2016 12:41PM EST
IMPORTANT NOTE - Support for Internet Explorer Versions 10 ends on January 12, 2016 because Microsoft will no longer support it after that date.
All connections to Click & Pledge payment pages use a secure web connection as indicated by the "https" and/or Green Padlock in the address bar. There have been different communications configurations (Protocols) used over the years to create a secure connection. Unfortunately, some of the older ones are no longer secure.
SSL 2.0 and 3.0, and TLS 1.0 are vulnerable to "Man-in-the-middle-attacks". This vulnerability is known as the "POODLE" vulnerability, which was a major topic in the media in the last quarter of 2014. At the time only affected SSL 2.0 and 3.0. It was later determined that TLS 1.0 was susceptible to a similar means of attack.
In order to maintain a secure connection for our customers, Click & Pledge disallowed SSL 3.0 on all systems in November 2014. We have also phased out the use of TLS 1.0 over the last few months as the percentage of browsers that can use TLS1.1 and above reached an acceptable level.  
Many browsers now update encryption settings automatically. A notable exception, however, is Microsoft's Internet Explorer. IE 9 and below are not supported. IE10 does not allow TLS1.1+ connections by default but the user can change those settings. See this help article for information on setting up IE10.
Since affected browsers do not provide appropriate error messages, Click & Pledge suggests you add a warning near the donation form link (or above the frame) that states that "The donation form uses modern secure encryption technology: older browsers may not be able to view the page (frame) at all. If you cannot see the form, please choose another browser to view"

Below is a list of the minimum version that supports TLS1.1 and above for each of the major browsers.
