Proofpoint Prime

What it does

Proofpoint Prime is a human-centric email and collaboration security suite that consolidates multichannel threat protection, impersonation defense, and risk-based user education into one platform, built on the Secure Email Gateway (SEG) heritage of Proofpoint's email protection. Its distinguishing approach is the Nexus AI detection stack, which combines threat intelligence, large language models, relationship graphs, behavioral analysis, and computer vision to stop phishing, business email compromise (BEC), account takeover, and supplier fraud both before and after delivery.

How it works

Prime routes inbound mail through its detection stack, applying attachment and URL sandboxing, time-of-click URL rewriting, and anti-spam and graymail filtering, then continues protection post-delivery with automated message remediation and abuse-mailbox triage. It correlates identity and activity signals across Microsoft 365, Google Workspace, and Okta to detect account and supplier compromise, and monitors the internet for lookalike domains while managing DMARC to block domain spoofing. A Human Resilience Workbench scores user risk across behavior, role, and attack exposure, converting real-world threats into targeted simulations and in-the-moment coaching.

Credentials and traction

Proofpoint holds SOC 2 Type II, ISO 27001, and ISO/IEC 42001 certifications, and its Email and Information Protection and Targeted Attack Protection products carry FedRAMP Moderate authorization for U.S. public-sector use.
