AppDynamics, now branded Splunk AppDynamics, is an application performance monitoring product for hybrid and three-tier applications. It links application performance to business metrics and also covers application security, monitoring for SAP solutions and digital experience monitoring. It is aimed at IT and operations teams running applications on-premises, in private clouds and in public clouds. It is part of the Splunk Observability portfolio and can be used alone or with other Splunk products.
AppDynamics was founded in San Francisco, California, and has belonged to Cisco since 2017. After Cisco acquired Splunk in 2024, AppDynamics was folded into Splunk in 2025. The product therefore sits under a US parent company and US law, including the CLOUD Act, which can reach data held by US providers wherever it is stored. The software is proprietary. The vendor pages consulted do not state where monitoring data is hosted or whether an EU region exists, so a European organisation should clarify data location, retention and access terms before sending application telemetry to the service.
