Portal for ArcGIS 10.9.1 system requirements

The system and hardware required to run Portal for ArcGIS are listed below.

If you will license ArcGIS Pro, ArcGIS Pro extensions, or ArcGIS Drone2Map through ArcGIS Enterprise, you also need ArcGIS License Manager 2021.1 or a later release to configure licenses to specify which members can use these apps. See the Portal for ArcGIS administrator guide, License Manager reference guide, and License Manager system requirements for more information.

It's recommended that you review the deprecation notice to determine if your hardware and software components are still compatible with the current ArcGIS version.


ArcGIS Enterprise components require the Microsoft Visual C++ 2015–2019 Redistributable (x86 and x64) minimum version 14.22.27821. Obtain the Microsoft Visual C++ Redistributable for Visual Studio 2015–2019 file from the Microsoft site.

If the required Visual C++ Redistributables are not installed, running the Portal for ArcGIS setup.exe file will install them. Running the Portal for ArcGIS setup.msi file will not install the Microsoft Visual C++ Redistributables (x64). Therefore, if you want to run the Portal for ArcGIS setup.msi file, you must first install the Microsoft Visual C++ 2015, 2017, and 2019 Redistributables (x64).

Microsoft Windows operating system requirements

The following 64-bit operating systems satisfy the minimum operating system requirements. Support is not provided for 32-bit operating systems; the setup only proceeds if the operating system is 64 bit.

  • Prior and future updates or service packs for these operating system versions are supported unless otherwise stated. The operating system version and updates must also be supported by the operating system provider.
  • The Desktop Experience option is required on all versions of Windows Server.
  • Windows 10 and 8.1 are supported for basic testing and application development use only. They are not recommended for deployment in a production environment.
  • Machines with an underscore (_) in their names are not supported. Several widely used internet host name specifications have designated the underscore character as nonstandard. Although Microsoft Windows allows you to use the underscore in a machine name, it can still cause problems when you interact with other servers and platforms. For this reason, the installation will not proceed on servers that have an underscore in the host name.
  • You cannot install on domain controllers. Installing on a domain controller may adversely affect functionality.

Hardware requirements

The following are the minimum hardware requirements to install Portal for ArcGIS:

  • Processor: 2 cores minimum for development and testing, 4 cores minimum highly recommended for production systems
  • Memory/RAM: 8 GB
  • Disk space: 20 GB

All content created by your users will also be stored on disk. Carefully consider how data will be uploaded and created by your users and allocate disk space accordingly. If desired, you can change the location of where the portal stores its content after installing the software.

Firewall settings

Portal for ArcGIS communicates through specific ports. You'll need to open these ports on your firewall before installing the software. For information on the ports Portal for ArcGIS requires for communication, see Ports used by Portal for ArcGIS.

Domain name service and fully qualified domain name requirements

Your organization's domain name service (DNS) must include an entry of the fully qualified domain name (FQDN) of the machine hosting Portal for ArcGIS. Similarly, if you'll be using ArcGIS Server with your portal, it's recommended that you include FQDN entries for each site you intend to federate with Portal for ArcGIS.


Portal for ArcGIS only supports a single DNS.

Optionally, you can configure your DNS to use a friendly name for the portal (for example, instead of When doing this, assign the name to the portal machine before you install the software. Then use the friendly name when setting up the portal. For example, setup activities that require use of the friendly name include the following:

  • Configure ArcGIS Web Adaptor with your portal.
  • Federate an ArcGIS Server site with your portal.
  • Add Portal for ArcGIS to your organization's reverse proxy server. If you're not using a reverse proxy server, it's recommended that you assign a friendly name to the machine hosting ArcGIS Web Adaptor.

If you configure a friendly DNS name after setting up your portal, existing items in the portal may become unusable, as they will include the nonfriendly name. You'll need to manually re-create each item to use them again.

SSL certificates

Portal for ArcGIS is configured with a self-signed server certificate, which allows you to do initial testing of the portal and helps you quickly verify that your installation was successful. You must request a certificate from a trusted certificate authority (CA) and configure the portal to use it. The certificate can be signed by a corporate (internal) or commercial CA.

You should configure each applicable ArcGIS component in your organization with a certificate from a corporate or commercial CA. Common examples include ArcGIS Web Adaptor and ArcGIS Server. For example, ArcGIS Server includes a configured self-signed certificate. If you'll be federating an ArcGIS Server site with your portal, it's very important that you request a CA-signed certificate and configure the ArcGIS Server site and Web Adaptor to use it.

For more information, see Security best practices.

ArcGIS Web Adaptor

ArcGIS Web Adaptor is a required component of Portal for ArcGIS that allows you to integrate your portal with your existing web server and your organization's security mechanisms. You cannot deploy Portal for ArcGIS in your organization without the Web Adaptor.

You can only use the Web Adaptor with port 80 or 443. Using other ports is not supported. See the ArcGIS Web Adaptor documentation for details.

Supported web browsers

For the best performance in the portal website, use the latest versions of the browsers listed below. The website leverages the local storage capabilities (similar to cookies) of the browser. If this storage is disabled, the site will not function properly. To learn how to enable local storage, consult the browser's documentation.

  • Google Chrome
  • Microsoft Edge
  • Mozilla Firefox
  • Safari
  • Android Browser
  • Chrome for Android

Scene Viewer has its own browser and hardware requirements. Some of the apps used with ArcGIS Enterprise have different requirements. See their documentation for details.

External access

If you'll be using services provided by Esri, such as basemaps, ArcGIS Living Atlas of the World content, and data from ArcGIS Online, the machine hosting Portal for ArcGIS must have access to the internet. If your portal will not have access to the internet, you'll need to perform some additional configuration steps to ensure that your portal is pointing to local resources. For instructions, see Configure a disconnected deployment.

The machine hosting Portal for ArcGIS must also have access to the internet to use distributed collaboration with an ArcGIS Online organization.

Supported virtualization environments and cloud platforms

Virtualization and cloud environment support is the same for all components of a base ArcGIS Enterprise deployment. See ArcGIS Enterprise on cloud platforms and Supported virtualization environments in ArcGIS Enterprise system requirements for details.
