Overview
What is DigiCert DNS?
DigiCert® DNS is a modern, enterprise-grade DNS management platform that gives infrastructure and platform teams full control over DNS configuration, security, and operations across distributed environments.
Built to support complex, multi-tenant architectures, DigiCert® DNS enables centralized management of domain resources. It includes built-in capabilities for access control, performance optimization, and policy enforcement—reducing the operational overhead of DNS management by simplifying tasks such as:
Configuring domains and records at scale
Defining secure access boundaries across teams and services
Routing traffic based on policy, location, or latency
Managing users, credentials, and permissions, either programmatically or through the user interface
Whether you are supporting internal service discovery, public-facing applications, or isolated user zones, DigiCert® DNS delivers the essential tools to make DNS a strategic part of your infrastructure.
Why does DigiCert DNS matter?
In today’s cloud-native architectures, DNS is more than just a naming system—it functions as a foundational control plane for service discovery, traffic routing, and access enforcement. Every request, internal or external, depends on DNS to reach its destination. This makes DNS not only mission-critical, but also a prime target for misconfigurations, performance bottlenecks, and security threats.
DigiCert® DNS addresses these challenges by turning DNS from a static, peripheral component into a secure, observable, and programmable layer of your infrastructure. In dynamic, large-scale environments, centralized and automated DNS control is essential to:
Ensure service reliability and uptime through fast, accurate resolution and resilient nameserver configurations
Enforce security boundaries and policies at the network edge, where DNS acts as a first line of defense
Respond quickly to outages and incidents with real-time visibility and granular record control
Optimize user experience by intelligently routing traffic based on latency, geography, or custom policies
Without secure, managed DNS, even well-designed systems are vulnerable to misrouting, degraded performance, and downtime. DigiCert® DNS brings DNS under the same level of operational discipline as other core infrastructure, offering the tooling, access control, and automation required to deliver modern applications reliably and securely at scale.
