DigiCert DNS Trust manager vs Google Cloud Performance + Services

DNS doesn't have to be complicated

Learn how DigiCert DNS is more than twice as fast as Google Cloud in performance testing, and how we can work together to build complete redundancy.

Secondary DNS 

Google Cloud: None
Google Cloud DNS does not support traditional Secondary DNS,
which can be problematic for redundancy purposes. *However, you can use Google Cloud as a secondary provider if your primary provider supports Secondary DNS through API calls.

DigiCert DNS Trust Manager: Secondary DNS for Redundancy
DigiCert supports traditional secondary DNS
, which means you can use us as your primary or secondary provider. We work well with Google Cloud DNS, but in order to use them alongside DigiCert, we would need to be your primary DNS provider.

Failover Services

DigiCert DNS Trust Manager operates on its own extensive, bare metal server infrastructure and utilizes its proprietary Peregrine Instant DNS updates (PIDU) technology, which pushes DNS changes to our thousands of authoritative nameservers in less than a second, making our Failover service one of the fastest in the world.

Google Cloud: Failover for Network Load Balancing

Google Cloud provides a configurable failover policy for pools that is based on ratios that tell Google Cloud how to respond to the health status of your endpoint(s)/virtual machines (VMs).

DigiCert DNS: Failover

DigiCert DNS'
Failover solution is powerful, yet refreshingly simple to configure. It is designed to automatically redirect traffic to an alternative endpoint in the event of a failure with little to no downtime. This is achieved via health checks that not only monitor your primary resource but also verify the health of your backup resource(s) before just rerouting traffic there.

Global Traffic Steering vs Intelligent Traffic Steering

Google Cloud: Traffic Director

Google Cloud DNS runs on Google’s infrastructure, which is focused on cloud-based services and not DNS layer services. Google’s Traffic Director deploys your services across VMs or containers (Kubernetes) and can be used for simple load balancing or advanced, percentage-based traffic splitting in multiple regions.

DigiCert DNS: Global Traffic Directory (GTD)

DigiCert DNS' Global Traffic Director lets users create region-specific DNS records that can serve content based on user location. Records can be configured for six regions around the world. GTD intelligently routes traffic for optimal end user experiences and greatly improves performance, resolution accuracy, and speeds.

DNS Analytics

Google Cloud: None*

Google offers analytics for their Private DNS feature, which gives you access to logs of DNS queries received from VMs and inbound forwarding traffic within your own network(s). They also have Smart Analytics for cross-market, cloud solutions.

We offer true DNS-focused analytics
that provides in-depth, real-time reporting on your domain(s) query activity, including query logging and statistics. This solution is invaluable for gathering DNS infrastructure data, comparing trends over time, troubleshooting DNS errors and misconfigurations, researching threats based on historical domain data, optimizing performance, improving SEO, and more.

DNS Speed Comparison
Google Cloud

DigiCert DNS' speed beats Google Cloud on a global scale.
The lower number is better performing and represents faster speeds. The graph shown is based on a world view (4/2023)

1. DigiCert DNS- 16.26 ms
2. Google Cloud- 44.37 ms (more than twice as slow)

DDoS Attack Prevention with Anomaly Detection

Google Cloud: Anomaly Detection
Google’s Anomaly Detection is a statistical technique designed to identify outliers in time-series data. This service learns your traffic behavior over 90 days for daily detection or 32 weeks for weekly detection. Anomaly detection flags anomalies based on statistical significance. Best used for identifying trends and changes that affect your business.

DigiCert DNS Trust Manager: Real-time Traffic Anomaly Detection (RTTAD)
We offer a real-time monitoring service that uses machine learning to analyze and predict web traffic. With Real-time Traffic Anomaly Detection (RTTAD), you can view your DNS traffic in real time, and are instantly notified if any suspicious activity is detected. With RTTAD enabled, you can make proactive decisions rather than reactive ones and stop an attack before it can bring your domain offline. Our network is also engineered to protect against TCP state exhaustion attacks, reflection/amplification attacks, and application attacks. Best used for identifying unusual activity and stopping DDoS attacks.
