Ensuring the Availability of the Authoritative Nameserver

In the face of the ever increasing size and frequency of DDoS attacks, it is critical to build a secure DNS infrastructure, beginning with a strong nameserver. Secure64 DNS Authority is an authoritative nameserver appliance that is always available, even during high volume network attacks. This self-defending server incorporates built-in DDoS protection and a secure operating system to defend against attacks on DNS servers and it needs no security appliances to protect it - it can stand alone on the internet.

In addition, DNS Authority is not based on open source BIND, so it is immune to the many critical security vulnerabilities found in BIND each year. It is a high performance, highly available and secure nameserver.

Always Available. Never Compromised.


Secure64 DNS Authority provides built-in DDoS protection that instantly engages to identify and block TCP or UDP attack traffic from packet flood, reflected and amplified DNS attacks while it continues to respond to 100% of legitimate queries. It provides real-time alerts and attack characteristics through syslog and SNMP traps so remedial action can take place, but the DNS will continue to function throughout the attack.

High availability means more than just attack protection. DNS Authority also remains available during restarts. In large DNS infrastructures, these restarts can leave servers dark for many minutes, creating challenges for organizations that are trying to achieve 100% availability.

Authority also can be easily anycasted in any data center in the world, even without access to the routing infrastructure. The administrator can insert and withdraw servers without requiring router changes or deploying dedicated router hardware.

Authority is a different kind of nameserver, but it is still compatible with existing IT infrastructure. Authority directly reads existing BIND configuration files and is interoperable with nameservers running BIND, NSD, or Microsoft Windows DNS software.
