Vendor installation instructions

Note

This connector uses Azure Functions to connect to Proofpoint TAP to pull its logs into Microsoft Sentinel. This might result in additional data ingestion costs. Check the Azure Functions pricing page for details.

(Optional Step) Securely store workspace and API authorization key(s) or token(s) in Azure Key Vault. Azure Key Vault provides a secure mechanism to store and retrieve key values. Follow these instructions to use Azure Key Vault with an Azure Function App.

STEP 1 - Configuration steps for the Proofpoint TAP API

Log into the Proofpoint TAP console
Navigate to Connect Applications and select Service Principal
Create a Service Principal (API Authorization Key)

STEP 2 - Choose ONE from the following two deployment options to deploy the connector and the associated Azure Function

IMPORTANT: Before deploying the Proofpoint TAP connector, have the Workspace ID and Workspace Primary Key (can be copied from the following), as well as the Proofpoint TAP API Authorization Key(s), readily available.
