Features
Anti-Spam Technology
TetherFilter incorporates custom algorithms designed
to determine the source of electronic mail messages and,
with a high degree of accuracy, judge whether they are legitimate.
By using
content-free technology, TetherFilter does not exhibit
the same false positive characteristics of most current
anti-spam solutions. And clearly, improperly
marking legitimate messages in the electronic equivalent
of a garbage can can render a spam worthless to an organization.
Specific methods include:
- Email format checking
- Real-time black lists
- Algorithms for detecting automated bulk e-mailing software
TetherFilter also allows system administrators and individual
users, who are enabled by the system administrator, to define
a sequence of rules to customize TetherFilter behavior.
System Administrators can extend default behavior to look
for inappropriate, confidential, or potentially dangerous
electronic mail messages on the network. The open architecture
defined in TetherFilter gives system administrators the
ability to dynamically change behavior when high priority
emergencies emerge. And throughout the simple and clean web
based interface, Tethernet has produced a compelling and
powerful tool to remove unwanted mail from your e-mail server.
There is no longer any excuse for unwanted electronic mail
messages.
Anti-Virus Technology
TetherFilter and TetherScan use advanced virus scanning
techniques to keep harmful viruses out of your network. Free automatic
updates ensure you always have the latest virus definitions.
Hardened Operation System
Tethernet appliances use a customized version of the
Linux operating system. This operating system is optimized
for our application and is secured to prevent attacks from
the Internet. By only running the necessary system services
many
potential points of attack are eliminated.
Onboard Spam Storage
Tethernet appliances store all quarantined email on
the appliance itself. This takes load of of the primary
mail server's storage systems, keeping it from being overloaded
with junk email. This feature is not available on the TetherFilter 50.
Appliance
By combining the hardware and the software in one package
Tethernet can provide the tightest integration possible between
hardware and software. Since the system comes pre-installed
you avoid the time and trouble of configuring the hardware,
installing an operating system and the application. No compatibilities
issues, no worries
Easy Administration
Tethernet products are designed from the ground up to be the easiest systems to set up and install into your network.
By providing intelligent defaults these systems are nearly ready to go out of the box. Our software walks you through
the basic configuration and gets you up and running fast. Within 15 minuets of taking the system out of the box
you can see the flow of viruses and spam into your network come to a halt.
Additionally, we realize that one of the most costly parts
of any system is the ongoing system administration required.
That is why Tethernet systems require almost zero on-going
maintenance. Automatic user account creation, automatic virus
definition updates and software updates keep your system running
smoothly without your interaction. A simple to use web interface
lets you offload time consuming tasks, such as special exception
rule creation, to the end users themselves. They have the
control they want, and you don't have to be involved in every
change, unless you choose to.
