ArcGIS Enterprise is Esri’s comprehensive, on-premises or cloud-based GIS platform that enables organizations to create, manage, analyse, and share geographic information securely within their own infrastructure. It is the enterprise-grade deployment of the ArcGIS system, designed for organizations that need full control over data, users, security, and system integration beyond what ArcGIS Online offers.
In simple terms, ArcGIS Enterprise allows you to build your own private ArcGIS Online, installed and managed within your organization’s servers or preferred cloud environment.
