Email Boundary Encryption Service

Communicating with email involves risks; confidential or sensitive information may be intercepted and then read, deleted or altered before it reaches its intended destination.



MessageLabs Email Boundary Encryption Service ensures the complete confidentiality of email communications and all the information they contain. It achieves this by setting up secure private email networks linking our clients with their nominated partners. Every single email sent or received via these networks is fully and securely encrypted, with the application of encryption remaining totally transparent to both sender and recipient.

The service is based on TLS encryption to encrypt the whole email connection, between your mail server and your partners’ or clients’ mail servers. Enabling you to define and manage a completely comprehensive and automatically enforced encryption policy. Our email encryption service works seamlessly with leading email servers including email encryption for Exchange, Lotus Domino and Sendmail.

Easy to enable and requiring minimal management, MessageLabs email encryption service not only provides a high level of protection but also permits the scanning of all encrypted email (incoming and outgoing) for viruses, spam and other inappropriate content for clients taking those specific services.

Our encryption service sets up a completely secure private email network that connects your employees with the clients and partners you specify.

How Boundary Encryption.cloud works

Our email encryption service eliminates the need to set up, configure or maintain in-house appliances, gateway systems or software plug-ins. It requires no changes in user behavior and the maintenance of only one encrypted channel with Symantec.cloud.



  • Clients designate which of their mail domains they want encrypted and identify the partners with whom they want to exchange encrypted email communications
  • Symantec.cloud sets up a secure private email network that uses TLS encrypted tunnels
  • All emails sent between the clients’ mail server, our infrastructure and the clients’ designated partners travel via this network
  • Symantec.cloud authenticates mail server certificates, ensuring messages are only sent to authenticated servers
  • If a secure TLS connection cannot be established end to end, the email is not delivered and the sender is notified – there is never any ‘fall-back’ to unencrypted delivery.
