UltraTech Resources

About Ultratech

Based in Chesterfield, Missouri, UltraTech Resources is a Microsoft Certified Partner and business solutions provider. As well as providing networking services to small and medium-sized businesses, UltraTech host approximately 75 customer websites and the authoritative name server for over 100 domains.


To manage core IP services, UltraTech relied on DNS management tools built into Windows 2003 Server. However, with only Windows Firewall protecting their two internet facing servers, they were exposed to regular attack.

“We saw constant DDoS attacks on these servers,” recalls Robert Brown, Technical Lead at UltraTech. “At times our Internet connectivity was brought down due to the amount of traffic trying to hit the servers. It wasn’t uncommon for our site to lose Internet connectivity once a month because of an attack.”

Losing access to their websites was affecting customer satisfaction and with every attack diverting staff away from serving customers day-to-day requests, UltraTech’s reputation was just as exposed as their servers.


UltraTech purchased a DNSBOX master, with two slaves to serve external queries. The master was placed on the internal network behind a firewall and the two slaves in the DMZ.

UltraTech got more than an ultra secure easy-to-use DNS appliance. It also got a team of DNS experts who have deployed rock solid DNS solutions for customers of all sizes, all over the world.

Robert Brown agrees. “I can honestly say that working with ApplianSys technical support is consistently the best experience with any technical support that I have had. I always get to talk to a live person who actually knows the product and isn’t reading from a script.”


The new solution has made dramatic changes to DNS management at UltraTech Resources. Core IP services are secure, customers are happier and the administration workload is down.

“ApplianSys has made managing our DNS amazingly simple. Once the boxes were up and running, it was a case of ‘set it and forget it’. Protecting the master from the outside world has helped tremendously with our exposure to the Internet,” comments Robert.

“Our time spent administering DNS has dropped to virtually nothing,” he continues. “We can quickly set up domains or make changes to the master and it automatically updates the slaves. It’s made a real difference to customers who notice instant changes when they request updates to a host or MX record. DNSBOX makes it quick for them and easy for us.”
