DNS Blast is a purpose-built hardened DNS security appliance designed to protect against volumetric DNS DDoS attacks and a broad spectrum of DNS-based threats. It is available as both hardware and virtual appliances. Key capabilities include: - High-throughput DNS caching, rated at up to 17 million queries per second (QPS), designed for carrier-grade ISP and enterprise deployments - Built-in DNS Guardian, DNS Firewall, DNS Client Query Filtering, and a Hybrid DNS Engine for layered DNS threat defense - Real-time DNS traffic analytics for on-the-fly detection of DNS tunneling and data exfiltration attempts - Patented adaptive countermeasures to minimize false positives while maintaining service continuity - Protection against a range of DNS attack types including cache poisoning, zero-day exploits, data exfiltration, volumetric DDoS/DoS, and amplification/reflection attacks DNS Blast supports decentralized DNS deployment architectures, enabling organizations to place DNS services closer to end users, thereby reducing latency and improving resilience. This approach can eliminate the need for redundant DNS clusters, load balancers, and supplementary firewalls, reducing total cost of ownership (TCO). The product targets ISPs and large enterprises facing extreme volumetric DNS threats, particularly those amplified by unsecured IoT devices, mobile endpoints, and BYOD environments. It is designed to address the limitations of traditional firewalls, which are not optimized for DNS protocol-layer attack mitigation.
