Firewall Design, Implementation and Management


Network security is more important today than it ever has been in the past. With the advent of more sophisticated methods of network intrusion, you need to be sure that your firewall can handle the task of keeping your network safe.

At RSTG, we have years of experience with network security and network security devices. After utilizing many different devices over the years, RSTG has standardized on Untangle for almost all of our firewall implementations.

RSTG has deployed dedicated firewall configurations for companies and educational institutions ranging from ten users to over a thousand, utilizing both the free and commercial versions of Untangle.
