DNS Defender |
Protect Your DNS Infrastructure, Cut Costs and Drive New Revenues
DNS is the service on which other Internet services depend. Yet DNS protocols and infrastructure were not
architected for security and are vulnerable to an increasing variety of threats, from DDoS (distributed
denial of service) attacks to poison pill and cache poisoning attempts. Such attacks can exact a heavy toll
in network downtime, quality of service, liability, customer satisfaction and support costs.
DNS Defender is the first DNS firewall--designed specifically to safeguard DNS systems. DNS Defender uses
multiple layers of protection to defend against the full range of DNS attacks, preventing costly DNS
outages and maintaining optimal network performance in the face of the heaviest attacks and peak loads. DNS
Defender also improves network efficiency and streamlines network operations, saving substantial costs. And
it enables new and enhanced services, driving top-line revenues.
