December 18, 2013

REDWOOD CITY, California, December 18, 2013 /PRNewswire/ –

VantioTM CacheServe 5.4 introduces precision policies to rate limit DNS traffic in the
event of a denial of service attack

Nominum [http://www.nominum.com ]TM, the provider of integrated subscriber, network,
and security solutions for communication service providers (CSPs), today announced the
launch of its Vantio CacheServe [http://nominum.com/infrastructure/engines/caching-dns ]
5.4 software, which introduces ground-breaking rate limiting technology to allow CSPs to
minimize the effect of DNS amplification attacks on network performance.

Nominum’s Vantio CacheServe [http://nominum.com/infrastructure/engines/caching-dns ]
5.4 introduces industry-leading precision policies which can be used to rate limit DNS
traffic based on specific criteria, including by type of query, by client IP or response

The release of the latest version of Vantio CacheServe
[http://nominum.com/infrastructure/engines/caching-dns ] follows the worldwide launch of
Nominum’s network security solution Vantio ThreatAvert
[http://nominum.com/infrastructure/engines/vantio-threatavert ] last month. ThreatAvert
combines the power of the Vantio CacheServe
[http://nominum.com/infrastructure/engines/caching-dns ] and its precision policies with
the Global Intelligence Xchange
[http://nominum.com/infrastructure/global-intelligence-xchange ] (GIX) platform, a
real-time database of malware threats, to provide a foundational security layer to protect
CSPs from threats emanating from within networks.

Vantio CacheServe [http://nominum.com/infrastructure/engines/caching-dns ] DNS
software has a proven track record of defending against multiple attacks including botnet
related activities, malware exploits, DNS amplification, DoS / DDoS, and outbound spam.
The latest version of the software includes upgrades allowing:

        - Improved broadband subscriber experience during an attack by increasing
          bandwidth availability and decreasing the response time of DNS infrastructure
        - Increased protection of server and bandwidth resources
        - A reduction in the number of customers impacted by attacks, resulting in fewer

Hari Krishnan, Director of Product Management, Nominum, says: “Sophisticated DNS
amplification attacks are becoming an increasingly common problem for CSPs, who have a
responsibility to their end-users to deploy the most advanced protection for network
infrastructure to minimize impact to customer experience.

“Nominum is committed to developing ground-breaking security solutions to help CSPs
protect themselves, and their customers, by leveraging the expertise derived from our rich
heritage in developing the DNS architecture used by CSPs around the world.”

Craig Sprosts, VP of Product Management, Nominum, says: “The new precision policies
that have been applied to Vantio CacheServe
[http://nominum.com/infrastructure/engines/caching-dns ] and Vantio ThreatAvert
[http://nominum.com/infrastructure/engines/vantio-threatavert ] provide the only way to
stop the latest DNS amplification attacks using the DNS itself, without blocking
legitimate traffic. Only a month ago we launched Vantio ThreatAvert, which combines
precision policies with the unique capability of Nominum’s GIX platform to detect attacks
days, or even hours, before alternative solutions. The additional precision policies
available in this release, plus the real-time threat updates delivered by GIX, provide
unmatched protection against this critical threat to our customers worldwide.”
