Case Study

Delivering high-quality VoIP. Denying attacks.

Atlantech Online stands out in the fiercely competitive service provider market by delivering high-quality, secure, and reliable, communications services. But to deliver on that brand promise, the company has to ensure that its network is high performance, highly reliable and, of course, secure.

“I hate firewalls . . . but I enjoy working with the SRX Series, because it makes security easier. The security principles and syntax of Junos OS just make sense to me.”

Eric Van Tol, Operations Manager, Atlantech Online


In the fiercely competitive service provider market, Atlantech Online has experienced steady growth since it started serving business and public sector customers in 1995. Based in Silver Spring, Md., the company provides IP phone service, high-speed Internet and data connectivity, website hosting, server hosting, and colocation.

Business Challenge

It’s no secret that security threats are on the rise, but distributed denial-of-service (DDoS) attacks can be an especially ferocious problem. A DDoS attack on a service provider’s voice infrastructure can mean anything from a basic service outages to completely lost business.

Business Solution

Atlantech Online has deployed the SRX3600 Services Gateway in a high-availability cluster to protect its voice services that include its Class 4 soft switch, session border controllers, and voice media servers. It also uses SRX Series gateways to protect hosting, Domain Name System (DNS), and e-mail services.

Business Results

Juniper SRX Series gateways have given the Atlantech Online operations staff greater visibility into potential problems and allowed them to mitigate potential risks, and made troubleshooting easier at the same time.

“Our voice infrastructure is much more protected with the SRX Series gateways than before. And our relationship with Juniper is strong,” said Operations Manager Eric Van Tol.
