email2 is offered as SaaS, on-demand, hosted solution. While we host your Private Email Network (PEN), we do not replace any of the basic e-mail infrastructure you currently have in place. Once sent or retrieved, 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.
To sign up for a corporate branded Private Email Network, visit http://www.email2.com/get_your_own.
From a security perspective, even we can’t read your email2 messages or attachments. When you first enable your Private Email Network, we ask you to enter a Master Key (encryption seedkey) 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 PEN. 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 PEN acts as a transit gateway where all email2 messages are stored and exchanged, but NOT as your final email data store such as Microsoft Exchange or your local PST file.
