## Executive Summary

Mimecast is a long-running email-security company that serves more than 42,000 customers and reported $501.4 million in fiscal-2021 revenue before Permira took it private. It has been acquiring across insider risk, collaboration governance, and adjacent human-risk products to reposition toward what it calls human risk management, and it named Ranjan Singh chief executive in 2026. Mimecast pursues that move while overlaying the cloud mailboxes Microsoft and Google operate, and it concedes in an SEC filing that those owners offer functions similar to its own in their core mailbox services. It suits organizations consolidating email security, archiving, and training with one vendor, and it is easier to displace where a buyer treats mailbox-native protection as enough.
