Migration Planning Guide for Email Security Transition

This planning guide outlines the process for migrating from legacy secure email gateways (SEGs) to Proofpoint's human-centric security platform. It is designed for organizations currently using Barracuda, Cisco, Forcepoint, Symantec, Trellix, or Trend Micro. The guide provides step-by-step instructions to evaluate the effectiveness of existing email security, calculate operational costs, and choose an appropriate migration path. It details the importance of assessing current defenses, understanding the costs associated with legacy systems, and selecting from three migration options: augmenting with API-based protection, transitioning from API to SEG, or fully replacing the legacy system with Proofpoint SEG. Additionally, it emphasizes the need for a controlled pilot to validate results before full deployment, ensuring that organizations can modernize their email security without disruption. The guide concludes with recommendations for building a migration timeline that aligns with organizational needs.
