Overview
What is DigiCert DNS?
DigiCert® DNS is a modern, enterprise-grade DNS management platform that gives infrastructure and platform teams complete control over DNS configuration, security, and operations across distributed environments. With built-in access control, performance optimization, and policy enforcement, DigiCert® DNS centralizes domain management and simplifies 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 modern cloud-native architectures, DNS is more than a naming system—it underpins service discovery, traffic routing, and access control. Every internal and external request relies on DNS to reach its destination, making it both mission-critical and vulnerable to misconfiguration, performance issues, and security risks.
DigiCert® DNS transforms DNS from a static 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 risk misrouting, performance degradation, and downtime. DigiCert® DNS enforces consistent operational discipline across your infrastructure with the tooling, access control, and automation needed to deliver reliable, secure applications at scale.
