About Us

Mimecast Is Making Email Safer For Business. Mimecast’s security, archiving and continuity cloud services protect business email and deliver comprehensive email risk management in one fully-integrated subion service. Mimecast reduces the risk, complexity and cost traditionally associated with protecting email. You no longer have to manage an array of disjointed point solutions from multiple vendors. And you mitigate single vendor exposure if you have moved your primary email server to the cloud with services like Microsoft Office 365. Our best-of-breed services protect the email of over 15,000 customers and millions of users worldwide against targeted attacks, data leaks, malware and spam. We give employees fast and secure access to sensitive business information, and ensure email keeps running in the event of a primary service outage.
