Which features are included in Mimecast's Targeted Threat Protection?

Mimecast's Targeted Threat Protection is specifically designed to address the risks associated with email-based threats. The features included, such as URL Protect, Attachment Protect, and Internal Email Protect, enhance protection against malicious content intended to compromise the security of an organization.

URL Protect safeguards users from clicking on harmful links by scanning and rewriting URLs in emails. This provides real-time protection against phishing and other web-based threats. Attachment Protect scans attachments for malware before they are delivered to users, ensuring that potentially harmful files are neutralized. Internal Email Protect focuses on identifying threats originating from within the organization, thereby helping to mitigate risks posed by compromised accounts or insider threats.

These features work together to create a comprehensive strategy against a range of targeted attacks, ensuring a robust and layered security posture for organizations that rely heavily on email communication. The other options may include important security components but do not specifically encompass the focused and comprehensive approach of Targeted Threat Protection as articulated in option A.
