Crowdstrike Plugin for User Risk Exchange
This document explains how to configure the CrowdStrike integration with the User Risk Exchange module of the Netskope Cloud Exchange platform. This integration collects uids and their scores from CrowdStrike’s platform to Netskope. The fetched record types are hosts.

A Netskope tenant (or multiple, for example, production and development/test instances).
A Netskope Cloud Exchange tenant with the User Risk Exchange module already configured.
Your CrowdStrike instance credentials(Client ID, Client Secret) for API Token
A CrowdStrike Real Time Response Administrator role for Put RTR Script action
For each platform (Linux, Windows, Mac), there should be a response policy with Real Time Response (High Risk Commands) enabled.
All the policies under Real Time Response enabled.
