Technology
[INSERT EMAIL DEFENSE SERVICE NAME]’s service is
powered by MX Logic and the Threat Center. The
service architecture inherently provides a highly available and distributed
pre-processing email filtering network which has the following unique
characteristics:
In-line Message Streaming
Our service architecture creates a proxy gateway for inbound email to the
enterprise or destination mail host. The service never actually acknowledges
receipt of an email message. Instead, it accepts the inbound email traffic with
the Simple Mail Transport Protocol (SMTP) and immediately opens a connection to
the destination recipient email server. Messages are then passed through the
preprocessing filtering layers as they are streamed to the recipient SMTP
server. Once the recipient messaging platform signals the acceptance of the
inbound email, the accepted protocol message is then passed back to the
originating SMTP sender. Legitimate messages are processed in a network stream
environment and are never stored to disk by a third party.
High Availability and Zero Latency Message Delivery
By leveraging a "pod" (N+1) architecture we provide carrier-class availability
of filtering and delivery components. Messages traverse the network and
transparently pass through complex filtering layers without latency. Sub-second
processing provides for almost no delay, as messages are "proxy-streamed".
Component-based Filtering Layers Email Defense Service has several
layers of filtering technology that provide component-level integration within
the messaging stream. A single event channel provides for universal and
distributed configuration for enabling cross-filtering layer communication.
Modules and components subscribe and publish related data through the event
channel, which provides native application distribution capabilities. Modules
may be upgraded and revised without service interruption.
No Additional Hardware or Software Required
EMAIL DEFENSE SERVICE does not require any
additional hardware or software. You simply point your MX record located within
your DNS records to our inbound Message Transfer Agent (MTA). Recipient
auto-discovery technology provides for a seamless method of managing end-user
filtering data and policies with no additional integration.
