What is Mimecast's strategy for protecting against ransomware through email?

Mimecast's strategy for protecting against ransomware through email is focused on the ability to detect and block ransomware payloads effectively, as well as providing incident response procedures for when such threats are identified. This approach is important because it addresses both the preventative and responsive aspects of security attacks involving ransomware.

Detecting and blocking ransomware payloads ensures that emails containing malicious attachments or links are intercepted before they reach the user, thus minimizing the risk of infection and subsequent data loss. Furthermore, the incident response procedures are critical in guiding organizations on how to act quickly and effectively if a ransomware threat is detected, allowing them to contain and mitigate the damage.

While other strategies such as encryption and filtering with artificial intelligence play important roles in email security, they do not specifically target the unique characteristics of ransomware threats or address the need for immediate action as part of an incident response plan. Allowing users to report suspected ransomware is beneficial for gathering intelligence but does not constitute a proactive security measure against ransomware attacks in the same way that detection and blocking do. Therefore, the comprehensive approach embodied in the correct answer emphasizes the need for both preventive tactics and defined responses tailored to combat ransomware through email communication.
