Splunk AppDynamics On-Premises solution is for customers who want to maintain full control over their deployment of the software. With this type of implementation, Splunk AppDynamics has no access to the software or the data it collects and processes. Customers subject to strict regulatory requirements for data security may want to consider an on-premises solution. On-premises customers are responsible for encrypting their data by either using self-encrypting drives or other non-product solutions.
