Tamper Proof, Auditable and Secure Data

When email data is required for litigation or regulatory purposes it is essential that its evidential quality is provided and with Mimecast strong chains of custody are maintained through the whole lifecycle of an email.

Key information retained include:

• which mail server the message was accepted from and delivered to
• the data transmission timestamps
• final acknowledgments issued from and to these servers 

Without this information you may not be able to conclusively prove that a message was delivered by you to your intended recipient, or indeed that a message was delivered to you from from the claimed sender.

Access to your data is only possible by your authorized administrators via a secure authenticated log-in to your Mimecast account. All access to your data by your administrators is logged in a comprehensive access audit trail. Each file is encrypted uniquely and receives a unique checksum on entry. Mimecast can therefore certify that your data has not been tampered with since it entered the Mimecast archive should it be required for legal or regulatory investigations.
