Mimecast
42,000 organizations. 175+ countries. 27 million people. For over 20 years, Mimecast protected the channel where work was most concentrated. The channel has changed. Today we're a unified platform that secures humans, data, and AI — because the attack surface is no longer a network. It is the workforce itself, now joined by AI agents that act with human permission and move at machine pace. Every employee. Every agent. Every file they touch. All of it protected so the work people do, and the work they do with AI, stays whole. Work Protected.
