About Cisco pxGrid Cloud

Cisco pxGrid Cloud is a cloud-based solution that enables you to share contextual information between on-premises applications such as Cisco ISE and cloud-based solutions such as Cisco Secure Access without compromising the security of your network. It is secure and customizable, enabling you to share only the data that you want and consume only the contextual data that is relevant to your application.

Cisco pxGrid Cloud offers the following benefits:

  • Plug-and-play deployment without requiring infrastructure changes to your network.
  • Cisco ISE as a single source of truth for endpoint identity by delivering consistent context exchange with on-premise and cloud partners.
  • Enrichment of Software as a Service-based (SaaS-based) security analysis with real-time endpoint context from Cisco ISE.
  • Threat containment by isolating endpoints from the network through actions initiated from the security SaaS solutions.

Cisco pxGrid Cloud Terminology

The following are some of the common terms that are used in the Cisco pxGrid Cloud solution and their meaning in the Cisco pxGrid Cloud environment:

  • Offer—A set of capabilities packaged together and offered as a solution.
  • Subscription—An instance of an offer being consumed by a tenant is a subscription.
  • App—You can create and register applications for your product based on your requirements. For example, you can create an app that can retrieve the session and endpoint data from Cisco ISE.
    Applications with a cloud offering can be onboarded to Cisco pxGrid Cloud. After an application is onboarded, you can share data between your Cisco ISE deployment and the application.

Prerequisites

  • Complete information about Cisco pxGrid Cloud and Cisco ISE Integration can be found in the Cisco pxGrid Cloud Solution Guide.
  • Ensure that you have installed and activated the Advantage license in your Cisco ISE deployment.
  • The pxGrid Cloud agent creates an outbound HTTPS connection to Cisco pxGrid Cloud. Therefore, you must configure Cisco ISE proxy settings if the customer network uses a proxy to reach the internet. To configure proxy settings in Cisco ISE, navigate to Administration > System > Settings > Proxy.
  • Ensure that port 443 is open for outbound connection from Cisco ISE to Cisco pxGrid Cloud portal. If firewall or proxy settings are configured, ensure that the following URLs are not blocked:
  • You must have administrator privileges to Cisco ISE and Cisco pxGrid Cloud to perform the activation.
  • Cisco pxGrid Cloud was introduced with ISE 3.1 Patch 3. It is generally recommended to use the latest patch for your ISE release.
