Proofpoint PX is a cloud-based email security solution that detects and filters messages containing threats such as Business Email Compromise, phishing, and malware. The platform provides message quarantine capabilities for analysis and disposition of suspicious content, along with functions to quarantine delivered messages that contain threats. It offers multiple layers of security to detect and block both malware and non-malware threats through automated and manual response processes. The solution ingests threat information from multiple alert sources and integrates with mail servers including Exchange, Office 365, and G Suite to retrieve and move messages. Proofpoint PX is designed for use with external business messaging traffic flowing through Microsoft O365 application instances.
