Select the proper TLS version when initiating outbound connections from Pega Platform to external servers and systems, for instance, when configuring authentication services, authentication profiles, and connectors.
TLS is a cryptographic protocol that provides communications security over a computer network. For outbound connections from Pega Platform, consider the following recommendations when choosing the lowest allowable TLS version for communicating with your identity provider or external application:
- For applications built with Pega Platform version 8.7.2 and higher, select TLS 1.2 for outbound connections if the server supports TLS 1.2.
- If you updated to Pega Platform version 8.7.2 or higher from version 8.4.6 or earlier, edit your rule form for outbound connections to use the appropriate protocol supported by your Pega application's underlying Java version. Pega has observed cases where some features, such as customer search, fail to work when the lowest allowable SSL/TLS version is set to 1.0.
