Secure User Messaging
Isode User Messaging products provide end-user access to secure email and military messaging services using open standards.
Isode User Messaging products provide end-user access to secure email and military messaging services using open standards.
Isode’s messaging servers provide access with Internet Standard SMTP and IMAP protocols, so that any modern email client can be used with the servers. The servers provide capabilities useful for military messaging, but can be used for a wide range of email services. Harrier, Isode’s messaging client, has a wide range of military messaging and general-purpose email features.
There are three central components to Isode’s user messaging service, shown in the above diagram.
- Harrier is Isode’s messaging client that can be used for email or formal military messaging. It provides security with S/MIME and security labels, and specialized military messaging handling capabilities.
- M-Box provides Internet message storage and is accessed by Harrier using the Internet Message Access Protocol (IMAP). It is a general-purpose, high-performance message store.
- M-Switch User Server is used by Harrier to submit messages using Simple Message Transfer Protocol (SMTP). It can transfer messages to other message servers using SMTP and provides a wide range of additional capabilities, with options to support additional protocols. M-Switch User Server is monitored and managed with the MConsole tool.
The User Messaging servers use Internet Messaging standards (SMTP and IMAP). Access to other protocols, in particular the ACP 127, ACP 142, and STANAG 4406 military messaging protocols, is provided by M-Switch Gateway, which provides protocol conversion and relay. These protocols can also be provided directly by M-Switch User Server
Underlying the User Messaging Service is Isode’s M-Vault directory service that provides address book and configuration services, supported by Isode’s Cobalt product for provisioning services.
