E-mail over Internet is as insecure as a postcard. MEI's TLSGate creates encrypted connections between selected mail servers for strong security protecting email traffic. When augmented by SpamGate and VirusGate, TLSGate provides state-of-the-art security and defense against mail abuse.

• Email is transmitted in clear text, so confidentiality is impossible exactly where strict confidentiality is required. Furthermore, all of the mail headers ( "MAIL FROM: Sender@SenderDomain", etc) are easily forged.
  
  
• One solution is end-to-end encryption (PGP, S/MIME) where the sender of the message encrypts the message and the recipient decrypts the message. The encryption is secure and popular but it is one-to-one and each "one" (sender/recipient) must manage encryption keys. End-to-end encryption is difficult to implement in a many-to-many environment, say between between two mail domains with 10's or 100's of users in each domain. The end-to-end encryption also prevents virus scanning by mail servers, since the virus scanner does not have the key to decrypt the message.
  
  
• VPN (Virtual Private Network) is another option for securing mail, but VPN is not appropriate in all situations, such as when "inside-to-inside" virtual networks are not appropriate between two different organizations. The organizations only want secure mail transport, not access to each other's internal networks seen as one virtual network.

• Creating a secure mail connection between two TLSGate machines, TLSGate requires no modifications to workstations or the main mail servers. The gateway-to-gateway encryption starts and stops at each TLS gateway and is completely transparent to email users of either domain.
  
  
• While our illustration shows only two Email TLS gateways for graphic simplicity, any number of TLSGate machines can transport mail securely among themselves to create a virtual, secure, "many-to-many" private mail network.
  
  
• A TLSGate server can of course provide standard, insecure mail exchange with other Internet mail servers, switching to secure mode when another TLS presents proper credentials.

• Option: to reduce spam and other email attacks coming from non-TLS servers on Internet, an TLSGate can be augmented with MEI's SpamGate facility.

• Option: to reduce the threat of email viruses arriving from other TLS gateways or from any non-TLS Internet server, an MEI TLSGate can be augmented with MEI's VirusGate facility. While TLSGate protects mail exchanges with other TLS gateways, SpamGate protects the client's mail server from spam and other types of email-based attacks and abuse. SpamGate also delivers client's mail to Internet.
