The Gloucester-based company’s Boundary Encryption service effectively sets up a separate route out of a customer’s email server for messages that will be encrypted. It provides a secure private email network for communication with designated partners, using SMTP over Transport Layer Security (TLS) encryption, without the need for a crypto tool to be deployed on the desktop.
One of the great advantages in applying encryption on a boundary-to-boundary basis is that the corporate policy on securing email can be enforced without the need to involve end users in any decisions, or have them change work practices. Any aspect of the policy is out of the hands of individual users, said Jos White, president of MessageLabs.
White also said that a pre-set encryption policy for certain destinations, with no intervention by the individual users, has the advantage of complying with regulation such as HIPAA and the Gramm-Leach-Billey Act, which best effort encryption cannot.
