+
+We're excited to announce that Sumo Logic has fully transitioned to AWS Certificate Manager (ACM) certificates for Transport Layer Security (TLS) communication between your cloud syslog sources and Sumo Logic.
+
+In [a previous release note](/release-notes-service/2025/08/01/collection/), we announced that we are transitioning from DigiCert to ACM certificates.
+
+This change provides the following benefits:
+* **Automated certificate renewal and deployment**. ACM eliminates the need for future manual renewals, reducing administrative overhead.
+* **Simplified infrastructure management for AWS customers**. ACM is deeply integrated into the AWS ecosystem, streamlining your overall infrastructure management. Because Sumo Logic is also on AWS, using ACM provides a seamless experience.
+
+If you use cloud syslog sources to send data to Sumo Logic, download and configure the ACM certificate on your system. For more information and setup instructions, see:
+* [Cloud Syslog Source](/docs/send-data/hosted-collectors/cloud-syslog-source/)
+* [rsyslog](/docs/send-data/hosted-collectors/cloud-syslog-source/rsyslog)
