Managed Email Security
Our award winning email defense technology blocks over 99 percent of unwanted email, with industry-leading low rates of false positives (legitimate email misidentified as spam). This extremely accurate filtering is made possible by a combination of our advanced multi-layered filtering and our sophisticated quarantine management features. These services and solutions are highly reliable and available 24/7 and backed by our redundant message processing centers.
INLINE MESSAGE FILTERING AT THE NETWORK PERIMETER
A strong email defense is essential for every organization - and it's equally important that the service you choose filters your valuable email without the risks of delay and loss. The technology behind DefenderSoft’s in-line message filtering process leverages a proxy-based system that is more secure and risk-free than other services that employ the store-and-forward method of email filtering.
The flow of email makes the difference
While both the proxy-based and store-and-forward methods utilize the domain's mail exchange (MX) record for filtering, they differ in how email flows through the filtering layers.
Using a patent-pending, multi-layer filtering process and redundant processing centers, email messages travel through these filters where spam, viruses and worms and unwanted content are stripped and email attacks are blocked - allowing only legitimate messages to be delivered.
Leveraging proxy-based filtering technology, DefenderSoft’s entire filtering process takes less than a second, is invisible to your organization and is extremely accurate. Conversely, store-and-forward filtering writes and stores all email messages to disk outside the corporate firewall, filters them in succession, and then forwards them onto their intended recipients.
Reduced latency
Our email defense solution acts as a conduit between the email sender and recipient - filtering the message in-stream, real-time as it passes from the sender to the recipient. Because messages are never stored during the in-line filtering process, emails filtered by DefenderSoft experience sub-second delivery - avoiding the latency issues from high-traffic and overburdened queues commonly experienced with the pure store-and-forward method employed by other providers.
Email vulnerability risks are virtually eliminated
Using Intelligent Message Processing technology; this proxy-based filtering virtually eliminates message delivery risks. With the store-and-forward method used in other systems, email messages are subject to loss through systems outages, message interception, or corruption from an infected email base.
Secure Message Delivery
DefenderSoft Email Threat Protection solutions support SMTP over TLS, providing email delivery encryption which allows customers to easily send and receive email over a secure, end-to-end encrypted tunnel. Our data centers accept and filter encrypted inbound and outbound message and then delivers the email across a secure tunnel when recipients are TLS enabled. If a recipient is unable to receive a TLS encrypted tunnel, DefenderSoft ETP will deliver the message via standard SMTP. Messages sent and received via an encrypted tunnel and are still automatically processed by the Threat Data Center, where they are scanned to block spam, viruses, worms, phishing attacks, unwanted content and attachments and other email threats.
Removing the risk of delivery failure
This award winning proxy-based filtering approach also removes the risk of
delivery failure that results from 'network islanding,' which occurs when the
destination server identifies a message as undeliverable and the message becomes
stranded between the originating server and its destination. Our proxy-based
filtering removes this risk by never accepting responsibility for the delivery
of legitimate message traffic. If disaster strikes at the destination message
server, the email will bounce back to the sender normally as mandated by the
Simple Mail Transport Protocol (SMTP).
