In the past, firewalls were fairly simple.
They determined whether data
would pass from one computer to another based on a set of rules that looked at
the source or destination address and the communications port they were
transmitting on. If there was a rule allowing data to pass for a particular set
of characteristics, the two computers could communicate. This strategy worked
well in the beginning, however, over time, people who design and write
malicious software developed tools to work around these basic features. In
fact, the overwhelming majority of companies connected to the Internet have a
firewall, yet thousands experience losses due to a variety of attacks each
year. If your firewall technology is older than 2 or 3 years, it is likely that
it is incapable of stopping most of the latest threats.
ZeroThree Security has chosen network security solutions from SonicWALL.
SonicWALL has developed the most advanced and cost effective security solutions
in the industry. The following is a list of some of the key features available.

Unified Threat Management
SonicWALL's Gateway Anti-Virus, Anti-Spyware and Intrusion Prevention
Service examines all traffic passing through the firewall. It compares the data
to a signature database of thousands of known threats. In the event there is a
match, the traffic is stopped before it can do any harm. The database is
automatically updated every few hours protecting you against frequently
occurring zero-day threats. It can also be used to control non-business related
internet use such as streaming media, Peer-to-Peer networks, Instant Messaging,
etc. Traditional firewalls can't provide this protection because they do not
examine the data as it passes.

Content Filtering
It may be important for your company to be able to control what sites
employees can view on the Internet. Having an Internet use policy isn't very
effective if you don't have a way to enforce it. SonicWALL's Content Filtering
Service allows you to decide what categories of sites you want to block. With
CFS, you can choose to block access to sites with pornography, violence, drugs,
etc. In the end, you can increase productivity and reduce the legal and
financial risks associated with inappropriate Web browsing.

Virtual Private Network (VPN)
SonicWALL has long been one of the leading providers of Virtual Private
Network technology. If you have more than one location and you need the support
and reliability of a managed network, ZeroThree Security's VPN solutions will
help you connect your remote locations securely over the Internet.

Remote Access
SonicWALL allows you to connect securely to your corporate network from
anywhere in the world where you have Internet access. Utilizing a VPN client
solution, you can allow users to connect to corporate computer resources
without compromising security. You can choose who has access to which systems.
WAN/ISP failover
As companies become more and more dependent upon the Internet for their
business, an outage becomes a greater risk to their success. No high speed
connection is completely reliable. Even if your network is 99.9% reliable, that
means that during the course of a year you may be down for 8 hours or more. Now
you can dramatically reduce the risk of downtime by utilizing a second
connection to the Internet and SonicWALL's firewall can take care of managing
the connections. When your primary connection fails, the firewall automatically
detects that failure and begins routing traffic over your secondary connection.
When the primary comes back on line, the firewall returns everything to normal
operation. In addition, you can use the bandwidth of the second connection to
improve your overall network performance. Even if you have public servers, DNS
information can be automatically updated so that your Web or Email services are
not disrupted.

Secure Wireless
Many companies have been reluctant to deploy wireless because of concerns
over security. SonicWALL wireless solutions are secure because they use the
latest encryption technology. In addition, ZeroThree Security security
professionals are experts at deploying secure wireless solutions. SonicWALL
also has additional wireless features not found with typical SOHO solutions
such as wireless guest services that allow your visitors to use your wireless
network for access to the Internet without exposing your trusted network.
