The Transport Layer Security (TLS) protocol is a cryptographic protocol, which ensures communication security. The TLS Protocol provides privacy and data integrity between two communicating applications.The protocol is describt by the Internet Engineering Task Force (IETF) in Requests for Comments (RFCs). It evolves over time to support higher standards.
SAP Cloud Platform uses encrypted communication channels based on HTTPS/TLS. All platform regions launched before 1 July 2018 support all three version of the TLS protocol: 1.0, 1.1, and 1.2.
Following 1 July 2018, future platform regions will support only the more secure TLS version 1.2. Existing regions will continue to support versions 1.0 and 1.1. The timeline for disabling TLS 1.0 and 1.1 on regions provisioned before 1 July 2018 will be announced separately.
We announce the provisioning of new regions using the SAP Cloud Platform release notes. You can use them if you need to check the date when a particular region was provisioned.
Inbound HTTP connections relying on TLS 1.0 or 1.1 will not be possible. Make sure that the HTTP clients in use, such as web browsers, support TLS 1.2. In case TLS 1.0 or 1.1 is still needed, especially in integration scenarios with legacy systems, you may use a custom web domain, and enable TLS 1.0 or 1.1 for it. See Using Custom Domains (section Create an SSL Host part of Configuring Custom Domains).
In case you want to use soley the new standard you have to oppertunity to choose a region which does not support TLS 1.0, for example.
