Cloud Exchange System Requirements

This section describes the system resources and software requirements required for the Netskope Cloud Exchange installation. Please note that an installation using Amazon ECS is slightly different. For more information, refer to the Install Netskope Cloud Exchange with AWS ECS Fargate.

Netskope Cloud Exchange uses a setup script to verify that the host system is ready to run the Cloud Exchange platform. In addition to compute and storage size, permissions, and some software versioning on the host, Cloud Exchange needs access to GitHub, Docker Hub, a Netskope tenant, AWS, and other 3rd-party platforms you want to integrate. Evaluate your system readiness to help the setup complete successfully.

For Cloud Exchange containers on the same host to communicate with the RabbitMQ container, ensure that the host has port 15672 open for sessions originated from the same host.

  • 4 CPUs. From Cloud Exchange v4.1.0 onwards, only x86 architecture with Advanced Vector Extensions (AVX) is supported. x86 architecture is supported on Cloud Exchange v4.0.x and older releases.

  • 4 GB of Memory

  • 40 GB of Free Storage (recommend you provision at least 40GB of host storage). Refer to System Sizing Recommendations.

  • Ubuntu 20.04 LTS, CentOS 8, or Red Hat Enterprise Linux 7.9 and 8.0 (the only ones Netskope continuously qualifies).

  • The machine running the browser accessing the Cloud Exchange UI must be able to load fonts from and

  • Refer to System Sizing Recommendations for sizing requirements for different deployments.

The Netskope CE platform needs access to GitHub, Docker Hub, a Netskope tenant, partner's platforms, and the other 3rd-party platforms that you wish to integrate with. Do evaluate network configurations, like HTTP Proxy setup, Firewall rules, etc., to ensure the connectivity is available.

Here is the list of Public URLs that CE needs. While the setup script will check for all of these, it will not successfully complete installing CE unless these requirements are met. Firewalls, web proxies, gateways, and routers must be configured to allow CE to communicate with multiple services as described below.

For fetching third party plugins, confirm the system has access to:


For fetching alerts and events from Netskope tenant, confirm the system has access to:

  • https://*


If conditional access is enabled with vendors or SaaS apps for Netskope solutions or need to SSL Allowlist by IP instead of domains, your systems will need to ensure reachability to this list of Netskope consolidated IP addresses (for tenant access from Cloud Exchange in case firewall does not support FQDN based rules).

For pulling docker images from Docker Hub (connectivity to additional hosts may be required since the docker images will be behind a CDN), confirm the system has access to:







If you are behind an HTTP or HTTPS proxy server, for example in corporate settings, you need to add the proxy configuration in the Docker systemd service file. Refer to for details.

Refer to Required Network Connectivity for 3rd-Party Plugins for additional network connectivity requirements based on the plugins.

For extracting web transaction event streaming logs, confirm connectivity to (for US customers) and (for EU customers). Alternatively, ensure Cloud Exchange can access * (wildcard).

For CE usage reporting, confirm connectivity to

For connectivity to Cloud Exchange, ensure that the administrator can access the command line interface for Cloud Exchange via SSH (port 22)

For browser and API-based connectivity to Cloud Exchange, ensure users have access to Cloud Exchange via port 80 or 443 (by default) or via any alternative, non-standard port (recommended) configured during the setup.

The user running the setup script should have at least the following permissions:

  • Either the user should be part of the docker group or should have permissions to run docker commands. (Ignore for installations on RHEL OS)

  • You need to have sudo permissions.

Below are the prerequisites required for setting up Cloud Exchange on Linux distributions other than Red Hat.

  • Linux System capable of supporting release of docker and docker-compose.

  • docker (minimum version 19.0.0): Refer to for installation instructions. Verify the versions with this command. Setup script will confirm.

    $ docker version

  • docker-compose (minimum version 1.29.0): Refer to for installation instructions. Verify the version with this command. Setup script will confirm.

    $ docker-compose version

  • Python 3 (for the setup script): Refer to for installation instructions. Execute this command to ensure you have the 3.x version of python installed. Setup script will confirm.

    $ python3 --version

  • Zip (For the diagnose script): Execute this command to verify if the command is available. If available, the command execution will output the path where zip commands are available.

    $ which zip

  • Git: Refer to for installation instructions. Execute this command to verify it is available.

    $ which git

Podman is a prerequisite to installing the Cloud Exchange platform on Red Hat Enterprise Linux (RHEL). Ensure these commands are available:

  • Zip (For the diagnose script): Execute this command to verify that the command is available. If available, the command execution will output the path where zip commands are available.

    $ which zip

  • Git: Refer for installation instructions. Execute the command mentioned below to verify that the command is available.

    $ which git

This section provides recommendations and guidance for selecting the memory/storage/CPU based on the expected volume. Factors include:

  • Total number of Indicators expected to be stored in the database. This factor defines the storage requirements.

  • Netskope Cloud Exchange has a “worker-based” scheduling mechanism to cater to the data pull/push for multiple data sources. The number of workers determines how many data sources will be actively fetching data/sharing data concurrently. The total number of worker processes should be equal to the number of cores. If the expectation is to fetch data frequently with multiple data sources, consider increasing the number of cores.
