Mimecast (Nasdaq: MIME) is a SaaS/Cloud company focused on enterprise email security and archiving. The story is a little mixed up though. The company focuses on email but is positioned (at least by Gartner Group) as an information archiving company. There are also some misleading statements regarding market opportunity to take into consideration as well. The vast majority (96%) of customers buy their email security add-on for Microsoft Exchange, Microsoft Office365 and Google Apps. Beyond that a good portion (2/3rds) add an "email continuity" service which keeps enterprise email running even when there are problems . . .
