Nominum security features currently protect more than 150 million broadband Internet subscribers around the world.  DNS is essential to the proper functioning of the Internet and securing DNS is critical to ensuring the integrity of e-commerce and the billions of other business and social interactions that occur on public and private networks every day.

Nominum has always been proactive in recognizing threats to the DNS and developing features to deter them.   Layered defenses for the Vantio™ caching DNS server lead the industry with superior protection against cache poisoning and other threats such as DoS attacks. The advantages of layered defenses were clearly highlighted in the summer of 2008 when Nominum was the only vendor that could definitively deter the extremely effective Kaminsky cache poisoning attack.  

Leveraging the DNS to protect subscribers as they browse, interact, and transact on the Internet is another area where Nominum is demonstrating leadership.  As the sole resource in the Internet responsible for navigation, the DNS is used by virtually every legitimate IP application; but attackers also depend on the DNS to launch their exploits.  Since the DNS is an integral part of Internet attacks, it must become an integral part of Internet defenses.  Nominum’s TRUE Architecture is the first effective carrier-class solution that implements DNS-based active policy enforcement to protect Internet users from web-based threats in real time on a massive scale.
