Portal for ArcGIS provides you with the same collaboration and sharing tools as ArcGIS Online, but differs in where it is hosted and what content is available to users. Portal for ArcGIS can be deployed behind your organization's firewall or a private instance can be hosted and managed by Esri for your organization.

With Portal for ArcGIS you can

• Manage your organization's geospatial content
• Access a set of common basemaps, tools, and task services
• Create maps and apps
• Share maps and apps with others inside or outside the organization
• Register your existing ArcGIS for Server services
• Form groups to collaborate on projects or common activities

If your organization has highly confidential and proprietary data, conducts confidential research, or has regulated data restrictions, then Portal for ArcGIS is the ideal solution for you.
