Proofpoint is an enterprise email security company — providing AI-powered email threat detection, Business Email Compromise (BEC) protection, security awareness training, and data loss prevention for enterprise organisations. AI-powered Email Threat Detection uses ML to identify phishing, malware, and BEC attempts in email — analysing email sender reputation, content patterns, link behaviour, and attachment characteristics to block threats before they reach employee inboxes. BEC Protection specifically targets the social engineering attacks where attackers impersonate executives, vendors, and finance teams to authorise fraudulent payments or data disclosure — Proofpoint's BEC models detect the subtle patterns in social engineering emails that traditional email security misses. Very Attacked People (VAP) identifies the highest-risk employees in the organisation — the specific individuals most targeted by threat actors, enabling targeted security controls and training investment. Security Awareness Training (integrated with Proofpoint) provides the education component alongside technical email security — phishing simulations and training modules complementing the technical email filtering. Data Loss Prevention (DLP) prevents sensitive information from leaving the organisation via email — identifying and blocking emails containing PII, credit card numbers, proprietary data, and regulated content. Targeted Attack Protection (TAP) provides advanced analysis of URLs and attachments — detonating suspicious links and attachments in sandboxes before delivery. With Fortune 2000 enterprise deployment, Proofpoint validates for organisations requiring comprehensive email security.
Proofpoint AI runs as ml platform software built around text and data workflows. Users typically start with a prompt, upload, or connected data source, and the underlying model handles the heavy lifting before returning a result you can refine or export. It's available on web, api, and email gateway.

High-risk employee identification from threat actor targeting patterns — enabling prioritised protection and training investment for the most targeted individuals.
URL and attachment sandbox detonation before delivery — catching zero-day threats that bypass reputation-based email security filters.
