ProofPoint TAP Solution: Fixed ARM Template Validation Failures

What Changed

Fixed ARM Template Toolkit (ARM-TTK) validation failures in the ProofPoint TAP solution package. The changes affected the mainTemplate.json deployment template.

Security Impact (Visibility & Fidelity)

Labeled P0 — assess deployment or pipeline breakage risk explicitly.

The ARM-TTK validation failures prevented successful deployment of the ProofPoint TAP solution from Content Hub. Organizations attempting to install or update the ProofPoint TAP solution would encounter deployment errors, resulting in a complete blind spot for ProofPoint email security telemetry.

ProofPoint TAP provides critical email threat intelligence including malicious URLs, file attachments, and campaign attribution data. Failed deployments meant no ingestion of email attack vectors, phishing campaigns, or threat actor infrastructure indicators.
