Email Server to Server Encryption for cost-effective email encryption
The key features of Google TLS are:
Encrypted messages from Email Server to Email Server:
TLS uses Public Key Infrastructure (PKI) to encrypt messages from mail server to mail server. This encryption makes it more difficult for hackers to intercept and read messages.
Authentication of sending and receiving servers:
TLS supports the use of digital certificates to authenticate the receiving servers. Authentication of sending servers is optional. This process verifies that the receivers (or senders) are who they say they are, which helps to prevent spoofing.
Policy based encryption and authentication:
TLS supports the use of digital certificates to authenticate the receiving servers. Authentication of sending servers is optional. This process verifies that the receivers (or senders) are who they say they are, which helps to prevent spoofing. Google TLS can be configured to require a TLS connection for specific domains to enforce security if required.
Mail Flow Diagram
Transport Layer Security (TLS), a protocol that encrypts and delivers mail securely, helps prevent eavesdropping and spoofing (message forgery) between mail servers. TLS connections are available for both inbound and outbound mail traffic. TLS is a standards-based protocol based on Secure Sockets Layer (SSL). TLS is rapidly being adopted as the standard for secure email.
The protocol uses cryptography to provide endpoint authentication and communications privacy over the Internet. TLS is the email equivalent of HTTPS for web communications and has similar strengths and weaknesses. Ask us for more details.
Domain Based Policy Enforcement
Google Transport Layer Security allows policy to be configured to use TLS either "opportunistically" - i.e. if the receiving mailserver is configured for TLS itself or on an "enforced basis" - requiring TLS to be used when receiving from certain domains or when sending to certain domains.
There are additional configurations possible and advanced certificate validation options. Ask us for more details.

Google Message Security, costs from £6 per user per annum; it provides virus detection, content and attachment policy management, TLS security and outbound email filtering and disclaimers.
Google Message Discovery, costs from £12.50 per user per annum ” adds archiving as a fully managed service for both external and internal email** and provides comprehensive search and audit facilities. This includes unlimited storage for a year's worth of message-data retention.
Retention periods can be increased up to 10 years from £22.50 per user per annum.
