Top 10 Best Business Email Compromise Software of 2026

Proofpoint Targeted Attack Protection is built to counter Business Email Compromise by isolating risky messages, performing impersonation-aware detection, and triggering automated remediation workflows. It analyzes phishing and payment-fraud indicators across inbound and outbound email paths, then rewrites or detours high-risk traffic before user interaction. The workflow design supports operations teams that need consistent enforcement, fast containment, and auditable responses during active impersonation attempts.

A key tradeoff is that aggressive detouring and isolation can increase user friction when legitimate messages are flagged for verification. Target it for environments with high email volume and common spoofing patterns, such as leadership impersonation and invoice or payment redirection scams. It fits incident-response workflows where quarantined and rewritten messages must be handled quickly to reduce downstream compromise risk.

Mimecast Targeted Threat Protection uses impersonation-aware analysis to catch targeted phishing patterns that evade generic filters by comparing identity signals from email content and directory context. The product ties detection to controlled response workflows, which helps teams contain messages fast by isolating emails and guiding users through the right actions. Post-delivery remediation includes message isolation and user-facing steps linked to the specific targeted threat pattern.

A tradeoff is operational overhead from running targeted response playbooks that require mailbox, directory, and user interaction tuning. This is most useful when adversaries use employee-specific impersonation, such as spoofed vendor invoices or executive account lures that rely on accurate role-based context. It also fits organizations that want coordinated containment after the first click to reduce repeat exposure across the same sender or impersonated identity.
