What is the primary benefit of Mimecast's Impersonation Protection policy?

The primary benefit of Mimecast's Impersonation Protection policy lies in its ability to verify sender identity. This policy is designed to protect organizations from impersonation attacks, where malicious actors attempt to pose as legitimate users or trusted contacts to deceive individuals or induce them into performing harmful actions such as transferring money or sharing sensitive information.

By focusing on sender identity verification, the policy inspects various characteristics of email communications to identify potential impersonation attempts. This may include cross-referencing sender information against known contacts, analyzing email content for suspicious requests, and using advanced machine learning techniques to detect anomalies. The result is a layer of security that helps to prevent unauthorized access and fraudulent transactions, significantly enhancing overall email security for the organization.

While detecting phishing attempts is a related area of security, impersonation protection is specifically targeted at verifying the legitimacy of the sender's identity, making it a crucial defense against social engineering tactics.
