Additionally, it provides advanced threat-hunting capabilities, allowing security teams to proactively investigate and respond to potential threats.

Microsoft Defender for Office 365 goes beyond email protection and extends its security features to other collaboration tools like SharePoint, OneDrive, and Teams. It scans files and documents stored in these platforms, ensuring that they are free from malware and other malicious content.

Proofpoint Email Protection is a machine learning email gateway that catches both known and unknown threats. Through Target Attack Protection, emails will be analyzed and potentially blocked from advanced threats while users gain visibility around these threats. The technology can also classify various types of email and can be deployed both on premises or as a cloud service. In addition, users can tag suspicious emails to help raise user awareness and track down any email quickly.

Proofpoint Email Protection offers Advanced BEC Defense, which can precisely detect and block different types of emails, even if they don’t involve a malicious payload, such as business email compromise (BEC). Email Protection, which is powered by NexusAI, is a sophisticated detection technique developed to stop a variety of kinds of email fraud from affecting compromised accounts. It’s specifically designed to analyze message components, such as the sender’s IP address (including reputation and x-originating IP), the message header, and the message body. Using machine learning and AI, it will then determine if that message is a BEC threat.
