Mimecast

Mimecast is a cloud-based email security and cyber resilience platform that protects organizations against advanced email threats including targeted attacks, phishing, impersonation, and malware. It provides email filtering, URL protection, attachment sandboxing, and data loss prevention for inbound, outbound, and internal email. 

Mimecast generates detailed logs for all email processing events including delivery, blocking, quarantine, URL click tracking, impersonation detection, and attachment analysis results. These logs provide security teams with full visibility into the email threat landscape, enabling investigation of targeted attacks, tracking of phishing campaigns, and detection of data exfiltration via email.
