ATMC Deploys A10 Thunder TPS to Protect Against
Growing DDoS and Application Attacks
Atlantic Telephone Membership Corporation (ATMC) is a nonprofit cooperative that is
owned by its members, the people of Brunswick County, North Carolina. ATMC not only
offers local telephone service, but also a wide variety of additional services, including
high-speed Internet, cable TV, wireless, business communications and security. ATMC’s
top priority has always been to provide the highest quality communications services and
customer service. It is dedicated to excellence as it delivers value to the customers in the
communities it serves.
Challenges
Distributed Denial of Service (DDoS) attacks are not only occurring more frequently, but
with greater volumes and increased sophistication. As organizations become increasingly
dependent on the availability of their services and on their ability to connect to the Internet,
loss of uptime means loss of revenue. A threat protection system that provides deep traffic
visibility to spot anomalies across the traffic spectrum is needed to protect against multiple
classes of attack vectors.
Faced with its particular security, performance and budget challenges, ATMC wanted a
solution that could handle high volumes of traffic while protecting against a growing
number of application and DDoS attacks. Modern Enterprise Solutions partnered with ATMC
to assist. “Our biggest challenge was finding something to handle the high volume of traffic
without negatively affecting the daily end-user experience,”says Mike Strider, Manager of
Data Services at ATMC.
Selection Criteria
Armed with a set of technical requirements, ATMC evaluated solutions from three different
companies to determine which would be the best fit. “A10 Networks was chosen because it
met all of our requirements,”Strider says. “It just works!”
“With the help of A10 Thunder TPS, disruption of multi-vector DDoS attacks
and the elimination of useless traffic before it penetrates our networks have
made a big difference to our business.“

Solution
ATMC selected A10 Networks® TPS™ line of Threat Protection Systems,
which enables service availability against a variety of volumetric,
protocol, resource and more sophisticated application attacks. Built
on the A10 Advanced Core Operating System (ACOS®) platform,
Thunder TPS delivers high performance and leverages a shared
memory architecture to provide efficient tracking of network flows, as
well as robust multi-vector DDoS protection enforcement for service
providers, website operators and enterprises.
Because ATMC is a service provider offering business and residential
broadband services, its network uses a multi-homed peering
configuration. In this deployment, A10 Thunder TPS has been
configured to protect the subscriber subnet in an asymmetric
proactive manner. ATMC is using Thunder TPS system logging to
establish a baseline alert threshold for its subscriber subnets. It then
creates DDoS events as required when under attack, and manages the
mitigations in effect for each incident.
Results
When asked to describe the single biggest value that ATMC has gained
from its A10 Thunder TPS solution, Strider notes the savings in overall
bandwidth utilization as well as the safety and security of infrastructure
against DDOS attacks. ”Disruption of DDoS attacks and the elimination
of useless traffic before it penetrates our networks have made a big
difference to our business,”Strider says.
Next Steps
Based on this very positive experience, ATMC is planning to explore
other A10 solutions that could help further its mission of providing
excellence and value to the community. Initially, it will be automating
the threat protection process with Thunder TPS.
About ATMC
A nonprofit, member-owned cooperative in North Carolina, ATMC
is dedicated to excellence in customer service and providing
communications services that add value to the communities it serves.
In the early 1950s, the large telephone companies of the day lost
interest in providing service to most of Brunswick County because
they thought it was too rural. A determined group of local people
worked to build their own telephone company, and in 1955, Atlantic
Telephone Membership Corporation (ATMC) was chartered.
Today, ATMC not only offers local telephone service, but also a wide
variety of additional services, including high speed Internet, cable TV,
wireless, business communications and security. Its top priority has
always been to provide customers with communications services at an
excellent value and with outstanding customer service.
