Secure Messaging

    Secure Messaging Service for Email


    Secure sensitive email communications

    As too many organizations have learned the hard way, sending sensitive information to third parties via email can lead to data exposure. Yet, the ability to communicate securely with customers and partners is essential. You need a simple, intuitive way for senders and recipients to safely exchange information via email, without burdening IT or relenquishing control of the data being shared.

    The Challenge

    The challenge of secure messaging

    Certain communications or files are so sensitive that delivering them via email using the open, public internet is unacceptable. But because email is still the most relied upon business application, employees generally want to use it to easily deliver and receive all their communications and files, whether sensitive or not. They don't want to learn another application and be forced to switch between systems to conduct business. Furthermore, employers don't want more complexity and cost associated with more third-party services.

    What organizations need is a user-friendly secure messaging service built directly into their email system that provides security and control over-and-above that which is provided using traditional email encryption, such as TLS.

    Our Solution

    Secure Messaging from Mimecast

    Mimecast’s Secure Messaging solution provides secure email communications right from your employees' email client. Administrators can set overarching security policies, which are applied automatically in the Mimecast service. Secure Messaging Service provides:


    A secure, cloud-based messaging service that enables the sharing of sensitive information and files initiated directly from within your employee's email client.


    Easy message and file access via a secure web portal hosted by Mimecast.

    Fully-customizable to ensure brand recognition and enhance recipient confidence.


    Granular message controls, covering message recall, expiration, automated read receipt, print and reply/forward control, which are applied by the sender or enforced using policies.
