email2 is offered both 'on demand', that is Software as a Service (SaaS) and as a 'Self-Host (host it yourself) solution for larger organizations and resellers.

As a service, while we host your Private Email Network, we don’t replace any of the basic e-mail infrastructure you currently have in place. Once sent or retrieved, secure email2 messages are stored behind your firewall as any other e-mail message. Your company retains total and singular control over all of its own data. What we host is a different gateway, instead of using the public SMTP domain, which is unsecure and unstable.

From a security perspective, when you first enable your Private Email Network, we ask you to enter a 'MAster Key' that is used as part of the AES encryption algorithm used to encrypt all your data for storage purposes.

email2 messages are transferred securely across the wire using HTTPS and are server-side encrypted as soon as they reach your Private Email Network. They are stored encrypted for the entire life cycle of your account and only accessible to people that you have sent these messages access to.

The email2 Private Email Network acts as a transit gateway where all email2 messages are stored and exchanged, but NOT as your final email data store such as MS Exchange or your local PST file.
