Technology Overview
mxSENTRY is powered by the Threat Center - our threat
monitoring center manned 24x7 that tracks spam all over the
world. The mxSENTRY 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
Our 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
mxSENTRY does not require any additional hardware or
software investment on your end. 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.
