When an organization signs-up for their own corporate, branded Private Email Network (PEN) using email2, they must enter an encryption seedkey, or password called 'Master Key' that will be part of the creation of a unique encryption certificate. This encryption certificate will then be responsible for encrypting all data-at-rest on the server, including attachments (AES 256-bit server-side encryption) stored on on the PEN. This means that nobody else can read, access or tamper with your secure messages along the way.

email2 messages are transferred across HTTPS connections, which are secure channels using a minimum of 128-bit SSL encryption - this is the same security used for online banking.

Form more information please request the email2 Security White Paper.
