Globus uses the Transport Layer Security (TLS) encryption protocol to secure network communications. In keeping with recommended security practices, Globus is deprecating TLS 1.0 and TLS 1.1 and requiring a minimum of TSL 1.2. This security upgrade will roll out across all Globus services and downloads during the week of August 27, 2018.
We expect this change to impact only a very small number of users. If you have any questions or concerns, please contact support@globus.org.
