Proofpoint

Proofpoint is the enterprise email security leader, protecting more Fortune 100 companies from advanced email threats than any other vendor. The platform specializes in detecting and blocking the sophisticated threats that bypass standard email security — targeted phishing, business email compromise, credential harvesting, and zero-day malware — using a combination of machine learning, behavioral analysis, and the world's largest threat intelligence network.

Advanced phishing protection goes beyond simple URL and attachment scanning. Proofpoint analyzes the behavioral characteristics of emails — writing patterns, sender authentication anomalies, display name impersonation, and conversation context — to detect social engineering attacks that contain no malicious links or attachments. This behavioral analysis catches the business email compromise attacks that trick employees into transferring funds or sharing sensitive data.

Business Email Compromise (BEC) detection specifically targets the fraud technique that costs organizations billions annually. By analyzing email headers, authentication records, domain reputation, and communication patterns, Proofpoint identifies impersonation attempts where attackers pose as executives, vendors, or business partners requesting financial transactions.

The Targeted Attack Protection (TAP) module provides advanced sandboxing for attachments and URL analysis. Suspicious attachments are detonated in isolated environments to observe their behavior before delivery, and URLs are analyzed at the time of click rather than just at delivery to catch time-delayed attacks.

Threat intelligence drawn from protecting tens of thousands of organizations provides visibility into emerging attack campaigns, allowing Proofpoint to deploy protections against new threats before they reach your organization. This crowd-sourced intelligence creates a continuously improving defense network.

Pricing is custom and enterprise-focused, typically requiring engagement with Proofpoint's sales team. The platform is designed for medium to large organizations where email security is a board-level concern.
