The correct answer is A. To automate the containment and remediation of email threats . Proofpoint’s Threat Response product description says that it removes manual labor and guesswork from incident response and helps organizations resolve threats faster and more efficiently. It provides actionable context and enables teams to quarantine and contain threats automatically or with minimal manual action. That aligns directly with automation of containment and remediation.

This is distinct from basic pre-delivery spam filtering or universal message encryption. CTR is not intended to manually inspect every email before delivery, and it is not just another spam engine. Instead, it is a response platform used after or alongside detection to orchestrate investigation, quarantine, and follow-up remediation actions for dangerous messages and associated affected users. In the Threat Protection Administrator course, Threat Response is positioned as the operational bridge between detection and action: once a threat is identified, CTR helps administrators and analysts contain it efficiently, especially at scale. That is why the product’s primary function is best summarized as automating the containment and remediation of email threats . Therefore, the verified answer is A
