Proofpoint Email Protection Reviews for 2025

What is Proofpoint Email Protection?

Proofpoint Email Protection is a highly effective email gateway solution that is capable of identifying both known and unknown threats that other solutions miss. It can be deployed as a cloud service or on-premises, and it runs on NexusAI, Proofpoint’s advanced machine learning technology, which can accurately classify different types of emails. This technology is particularly useful for detecting and blocking threats that do not involve malicious payloads, such as business email compromise (BEC), through its Advanced BEC Defense.

The service is unique in its ability to automatically tag suspicious emails, which helps to increase user awareness about potential threats. It also provides users with the ability to track down any email in seconds, giving them greater control and insight into their email security.

Proofpoint Email Protection uses multiple layers of detection techniques, including reputation and content analysis, to protect against constantly evolving threats. This comprehensive approach ensures the dynamic classification of a wide range of emails, including phishing, malware, BEC threats, bulk email, spam, and more.

One of the most important features of Proofpoint Email Protection is its Advanced BEC Defense, which is powered by NexusAI. This defense mechanism is designed to prevent a variety of email fraud, such as payment redirect and supplier invoicing fraud from compromised accounts. It employs a sophisticated detection engine powered by AI and machine learning, specifically designed to detect and prevent BEC attacks. The engine examines multiple message attributes, such as message header data, sender’s IP address, and message body for urgency and words/phrases, to determine whether a message is a BEC threat.
