The challenge

Email is the most-used communication channel—and the top threat vector—for most organizations. Phishing, ransomware, and business email compromise (BEC) attacks can lead to financial loss, data breaches, and reputational damage. As threats grow more sophisticated and compliance requirements tighten, businesses need more than basic spam filters. They need intelligent, adaptive email security that protects every message—before, during, and after delivery.

What is email threat protection?

As a multi-layered filtering tool, OpenText Core Email Threat Protection guards inbound, outbound, and internal email messages from email-enabled threats such as ransomware, phishing, impersonation, and spam. It’s designed to protect organizations from sophisticated email threats and reduce risk across all stages of email communication, while ensuring secure delivery of legitimate messages.
