The IronMail Privacy Architecture lets users choose among three distinct types of encryption and sending options for secure e-mail messages. The IronMail appliance comes with support for TLS (Transport Layer Security) enabled by default.
The second option is sending messages via the S/MIME (Secure Multipurpose Internet Mail Extensions) protocol, which uses the RSA encryption algorithm. Users also have the option of sending e-mails using PGP (Pretty Good Privacy).
All of the PGP and S/MIME operations are performed on the IronMail box.
Using the new architecture, the appliance is able to cycle through all of the sending options until it finds one that works for both the sender and receiver of a given message. That kind of usability is something that was conspicuously absent from earlier secure e-mail solutions, many of which required fairly advanced levels of security knowledge.
But now, with regulations requiring enterprises in some vertical industries to encrypt large amounts of their e-mail communications to ensure privacy and integrity, strong encryption is becoming a necessity.
"Were really seeing encryption become one of the main drivers with mail security," said Matt Anthony, director of product marketing at CipherTrust, based in Atlanta.
As part of the new architecture, CipherTrust also has formed partnerships with PostX Corp. and Voltage Security Inc. Both PostXs Envelope Server and Voltages Identity-Based Encryption Server can encrypt messages without the use of certificates, and neither solution requires a software download for recipients. Depending upon each customers policy requirements, the IronMail appliance will funnel messages to one or the other server accordingly.
The IronMail IPA is available now.
