You can use security information and event management (SIEM) integration to forward Zero Trust Branch events to your organization's SIEM platform for centralized security analytics. The integration supports real-time event streaming over syslog to platforms such as Splunk or other compatible SIEM engines. Within the Zero Trust Branch architecture, branch gateways securely stream events directly to the configured SIEM engine. Depending on your organization's requirements, you can deploy the SIEM engine either on premises or in the cloud.
