Due to a series of vulnerabilities in Secure Sockets Layer (SSL) and Transport Layer Security (TLS) over the past few years, as well as to meet the PCI Council’s requirements, GuideStar released security upgrades to our website and hosted platforms. We will only support TLSv1.2. Support for older versions of certain browsers may be dropped.
The browsers in question are:
- · Any version of Internet Explorer earlier than v11
- · Any Safari browser earlier than v7
- · Any Android browser earlier than v5
