# Introduction to IQService

IQService, also referred to as the Integration Service, is a native Windows service that enables SailPoint to participate in a Windows environment and access information only available through Windows APIs. It is a lightweight service that must be installed on any supported Windows Server that has connectivity to the target systems you want to manage in SailPoint.

> [!NOTE]
>
> The latest version of IQService is IQService-May-2025.

The following figure shows the communication flow of IQService with various end systems. A single IQService instance can serve multiple sources of the same or different source types. For enhanced performance, SailPoint recommends setting up separate instances for each of the sources. IQService supports setting up multiple instances on the same system, though these instances share the same system resources and it might degrade performance.

Securing all communications coming in and going out from IQService is very crucial to ensure overall security of the solution and data integrity. For more information, refer to [IQService Security Considerations](<https://documentation.sailpoint.com/connectors/iqservice/help/security/index.html>). IQService executable and libraries are digitally signed to ensure integrity of the files.
