Support for App Transport Security
Last updated 2018-08-03
Apple uses App Transport Security (ATS) to improve the security of connections between web services and applications installed on devices using iOS 9 or later, as well as OS X 10.11 (El Capitan) and later. Fastly is fully compliant with all ATS requirements. You shouldn't run into any issues supporting iOS or OS X users while using our service.
