# Configuring Talend logging modules with an external Elastic stack with X-Pack

You can deploy Transport Layer Security to the whole Elastic stack (Elasticsearch, Kibana, Filebeat, and Logstash). To do so, refer to the Elastic documentation: [Setting up TLS on a cluster](https://www.elastic.co/guide/en/elasticsearch/reference/7.x/ssl-tls.html).

Information noteNote: If you plan to upgrade your Elastic stack, Talend recommends to verify the upgrade requirements from Elastic, and to check the breaking changes between major versions. For details, refer to [Upgrading Elastic Stack](https://www.elastic.co/guide/en/elastic-stack/7.3/upgrading-elastic-stack.html).
