Multitenant environments allow Managed Security Service Providers (MSSPs) and multi-divisional organizations to provide security services to multiple client organizations from a single, shared JSA deployment. You don't have to deploy a unique JSA instance for each customer.
In a multitenant deployment, you ensure that customers see only their data by creating domains that are based on their JSA input sources. Then, use security profiles and user roles to manage privileges for large groups of users within the domain. Security profiles and user roles ensure that users have access to only the information that they are authorized to see.
