Our verdict on DigiCert UltraDNS
DigiCert UltraDNS is a cloud-based authoritative DNS service for organizations managing mission-critical or high-volume DNS workloads. It supports global query resolution, DNS security, traffic steering, failover, and operational automation. Its audience includes enterprises that need managed Anycast DNS, primary or secondary DNS deployments, geographic and ASN routing, and endpoint monitoring across a distributed environment.
The published Premium plan is built around custom enterprise-scale query volumes rather than a fixed public price. Its included capabilities cover a DDoS-protected global Anycast network, dual DNS redundancy, DNSSEC-enabled DNS, geo and ASN routing, and an automation API. Management is available through both a web portal and REST API, giving DNS teams a choice between visual administration and programmatic control. Primary, secondary, and hidden-master DNS support also allows UltraDNS to fit different authoritative DNS architectures.
UltraDNS stands out when traffic control and resilience matter as much as basic DNS hosting. Health checks and automated failover support continuity planning, while DNSSEC management addresses signed DNS requirements. The service is less suited to smaller teams seeking a self-service DNS product with a simple, publicly priced entry tier, since the Premium plan uses contact-sales pricing and emphasizes enterprise-scale operations. Choose it for managed global routing, redundancy, and automation; consider a simpler alternative if those controls exceed your DNS requirements.
