Configuring a cloud source in Scope is a two-step process.
Generating Mimecast API credentials in the Mimecast Administration Console. Please refer to Section 1 – Mimecast Setup
Setting up the Mimecast cloud source in the Scope application. Please refer to Section 2 – Scope Setup
To get started, you’ll need to generate the following credentials in the Mimecast Administration Console –
Log in to the Mimecast Administration Console.
Navigate to Integrations -> API and Platform Integrations.

Locate the Mimecast API 2.0 tile and click Generate Keys.

After reading the Terms & Conditions, complete the I accept check box to enable the Next button.

Complete the Application Details section:
Provide the application name
In the Category field, select the required category, for example SIEM Integration
In the Products field, select the minimum set of products the application needs to access
In the Application Role field, select Basic Administrator
Note: Mimecast recommend creating a dedicated custom role with only the permissions required for the application to function. Please refer to this [link] for more information on creating a custom role.
In the Description field, provide a description for the created application.

Provide details for a Technical Point of Contact.

Review the summary information for the API application and click Add application.

When the wizard completes, copy and save the Client ID and Client Secret from the pop-up window.
Note: Please make sure to save the API credentials in a secure location, as the credentials won’t be displayed after the pop-up window is closed.

The Client ID and Client Secret are to be configured in Scope Setup: Step 1 for initiating the Mimecast log ingestion.
Once the credentials are generated, they must be configured in the Scope application to establish the connection and enable data ingestion from the Mimecast environment.
In the Scope application, to register a Mimecast cloud source, navigate to the cloud source registration page –
Log into the Scope application
Select the required organization
Navigate to the Side menu -> Administration
Navigate to the Cloud sources tab
Click on the +Add Source button
In the Add Source pop-up, provide the parameters below.

Version: Select Version 2 for registering a Mimecast API 2.0 application. By default, Version 2 is selected.
Client ID: The Client ID generated in Step 1.

Polling Interval: The polling interval for making periodic API calls to the Mimecast API. The user can select the time interval from the dropdown.

Once the required connection parameters are entered, the Mimecast cloud source registration is complete in Scope and is ready for ingestion of Mimecast logs.
