REDWOOD CITY, Calif. -- Nominum, the provider of integrated subscriber, network, and security solutions for communication service providers (CSPs), today announced the launch of its Vantio CacheServe 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 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 size. The release of the latest version of Vantio CacheServe follows the worldwide launch of Nominum’s network security solution Vantio ThreatAvert last month. ThreatAvert combines the power of the Vantio CacheServe and its precision policies with the 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 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.
