Centralized DNS management, good traffic routing capabilities, and significantly improves DNS response times
Pros and Cons
- "We find that the low latency access to DNS queries has a direct effect on the customer experience. Visiting a site, whether it's an AdTech-based solution or marketing tech, the fact that whatever we're rendering on a page can be rendered better than the industry standard, in terms of time, ensures a better user experience."
- "We would really like them to become a DNS registrar."
What is our primary use case?
How has it helped my organization?
We needed to have the fastest and most secure and resilient DNS possible, and that's what we got. We don't worry about denial of service attacks on the DNS, as we've seen other large vendors go through. We have access to a significant and forward-thinking feature set that allows us to use things like DNSSEC fairly easily.
Our DNS response times have improved significantly. I have not compared data within the past year but at the time, we looked at a 99.9% evaluation and saw that NS1 was the most effective and fastest solution.
We have access to enterprise tooling that allows us to have a single pane of glass between our internal DNS solutions and our external ones. We also have the ability to use advanced routing techniques with the rules engine or the additional tooling that NS1 provides.
The application traffic management capabilities using the API are excellent. We orchestrate that API using Terraform, which means that there are no manual steps involved in bringing up a piece of infrastructure that needs a DNS record or maintaining hygiene in our DNS records because services are taken down. All of it is orchestrated with the use of the API with Terraform on top to achieve it. Overall, it's a very robust API and it meets our needs.
While it doesn't apply to the entire company, this product allows us to utilize automation through the API, which saves us a significant amount of time and eliminates manual changes that are error-prone.
We have been unaffected by major DDoS attacks because of the architecture.
This product has allowed us to reduce or eliminate DNS maintenance work. I can't estimate how much time this has saved us but being able to use an API versus manual maintenance means that we don't really have to do any maintenance. We've been given a solution that allows us to automate everything that we need to do.
The automation provided by NS1 means that we no longer have to focus on that work, which allows us to assign staff to other tasks. Time is saved because we don't really use manual processes with the DNS. We try to automate everything we do in the DevOps team, so this has been effective for us.
What is most valuable?
The most valuable features are the DNSSEC and the general reliability and speed of the service. We find that the low latency access to DNS queries has a direct effect on the customer experience. Visiting a site, whether it's an AdTech-based solution or marketing tech, the fact that whatever we're rendering on a page can be rendered better than the industry standard, in terms of time, ensures a better user experience.
The Application Telemetry feature is awesome. This includes latency detection and it allows us to detect where a customer may run into latency on the internet, giving us the opportunity to route around it. It contributes to providing the best user experience for our clients.
Using the Pulsar feature has certainly improved our user experience. Using Pulsar with telemetry monitoring between the customer and the endpoint, we are able to detect traffic and route it appropriately, which ensures the uptime of our applications and web properties. It also ensures that the lowest latency experience is possible.
What needs improvement?
We would really like them to become a DNS registrar.

Learn what your peers think about IBM NS1 Connect. Get advice and tips from experienced pros sharing their opinions. Updated: August 2025.
865,295 professionals have used our research since 2012.
For how long have I used the solution?
I have been using NS1 Managed DNS for approximately seven years, since 2014, across companies.
What do I think about the stability of the solution?
I don't have any issues with stability.
What do I think about the scalability of the solution?
Scalability-wise, I haven't had any issues with this product. It is being used wherever we're using DNS and as our business grows, it will be utilized more.
We have a DevOps team and an infrastructure team that uses NS1. The DevOps team mainly manages the automation of the cloud infrastructure and tools, whereas the infrastructure team manages our legacy on-premises data center.
This product provides the scalability we need to help meet SLAs and customers' demands without adding complexity, which is very important to us. Although it doesn't happen as often anymore, there can be significant changes in the demand for our service. This has the potential to overwhelm services, just like we see in denial of service attacks. However, the available capacity in NS1 has meant that we've never had a challenge with that.
How are customer service and support?
I have worked with the customer success team and the experience was world-class. They're a customer-first team and they are always available. We reach out to them on Slack and they're always there for us. They're straightforward and transparent about any possible issues that they have on their side and overall, it's a wonderful experience.
The same is true for the product's technical support. They're always there for us and transparent about any challenges.
Which solution did I use previously and why did I switch?
In the past, the company used Dyn, which is now by Oracle. I have also used UltraDNS.
There were several reasons that we switched. The number one reason is support and service, the second is the forward-thinking functionality and features, and the third reason is the cost.
How was the initial setup?
At this company, the initial setup was very straightforward.
It was an import, and it was completed in a matter of hours or less.
Our implementation strategy was to import or migrate the zones from a previous NS1 account that was owned by another company, and then make the necessary registrar changes. During our migration, there was zero downtime.
What about the implementation team?
I implemented NS1 Managed DNS at my current company. We completed the deployment in-house.
What was our ROI?
ROI is hard to quantify but in terms of application uptime and customer experience, we have seen a return on our investment.
What's my experience with pricing, setup cost, and licensing?
The cost of this product is one of the reasons that we chose it.
There may be overage costs in addition to the standard licensing fees, although I haven't experienced them.
Which other solutions did I evaluate?
I looked at the Dyn and UltraDNS solutions. I also looked at Akamai Fast DNS and some of the cloud services. The two main reasons that we chose NS1 are the low-latency DNS, and a feature set that was unique and seemed to be beyond what anyone else was doing.
What other advice do I have?
My advice for anyone who thinks that they don't need a solution like this because they have a free or basic DNS with their cloud provider is that they need to evaluate how DNS solutions may affect the customer experience. They should consider the global footprint of NS1, the network architecture, and where they implement Anycast. If these things don't matter then they're probably not running a business that relies on website revenue or has a website that represents their business.
The biggest lesson that I have learned from using this product is how easy it was to implement it, and that doing so probably reduces the risk of migrating to a new DNS solution.
This is a product that I have recommended to many different people. In general, I would say that this has been the easiest solution to manage and implement.
I would rate this solution a ten out of ten.

VP Information Technology & Cyber at a computer software company with 1,001-5,000 employees
Has good traffic management, speed of updates, and observability
Pros and Cons
- "Everything we download into our observability platform so that we can also track any changes in traffic behavior or things like that is also something that we use quite a lot. I'd say traffic management, the speed of updates, and observability are the top three things that we use."
- "There could maybe be additional ways to manage traffic. There are no major improvements we're looking for. It's a very complete solution."
What is our primary use case?
NS1 holds all of our domains.
When we started using it, we didn't use it with API automation. Today, we do everything with automation and run everything with our automation, so that any change we run, all the data is backed up with GIT. Changes are done with an API so that there is no manual work. It reduces errors significantly and allows us to quickly roll back all the activities on the platform. It works flawlessly for us. Deployments are very fast. There's absolutely no complaint there.
We manage our internet facing traffic with it.
How has it helped my organization?
We use it for traffic optimization. I have optimized the traffic using this feature by 20%.
DNS obviously plays a major role in DDoS attacks. It's something that is under attack, but it's also a major player in its ability to defend. NS1 has been doing an amazing job with that.
It has improved our DNS response times as well.
We've been using Managed DNS for the past 10 years. We moved from a different vendor a few years ago. Generally speaking, I would say that Managed DNS reduces the overhead.
NS1's automation has enabled us to assign tasks to other work because we have very little DNS right now because it's all managed. It frees up SRE time to deal with actual internal system and application management, instead of managing the infrastructure that can be managed by a third party.
It helped to improve our end-user experience because users get better service by accelerating the response time.
We have also seen benefits when it comes to speed, time, and cost.
What is most valuable?
The ability to manage traffic, what's called Smart Domains or Smart Record, enables us to provide our customers the relevant, closest data center by providing the correct IP address according to geography or other logic. The ability to see real-time performance is also very useful.
Everything we download into our observability platform so that we can also track any changes in traffic behavior or things like that is also something that we use quite a lot. I'd say traffic management, the speed of updates, and observability are the top three things that we use.
Observability means monitoring the API, the ability to see the traffic at the different levels, the ability to connect the right record to the right place, and then see everything within the platform or within our observability platform. It is really useful. The automation and the fact that they provide the connectivity into Terraform, for example, is very useful because it allows for ease of integration. I don't have to write the right API integrations myself. We can actually use industry standards that are available out there.
What needs improvement?
There could maybe be additional ways to manage traffic. There are no major improvements we're looking for. It's a very complete solution.
For how long have I used the solution?
I have been using NS1 Managed DNS for over four years.
What do I think about the stability of the solution?
The platform itself is stable and highly available. We had very few incidents and never full downtime.
What do I think about the scalability of the solution?
We have not found any scalability issues. We are running a pretty large operation ourselves, of around 100,000 requests per second, and we have never had any scalability issues with the platform. It's always scaled to the size that we need.
It provides scalability to help meet SOA and customers' demands without adding complexity. DNS is a basic part of any solution. And once you have 100,000 requests coming in and you need to make sure that the connectivity is there, the response time is there, the error levels are as low as possible, and every request actually gets an answer. If a third party can do this and I can take care of my actual application and not think about the path into my application, that is very useful.
How are customer service and technical support?
The only time we used support was when we migrated the additional features around security. They were highly professional and available. They are very good at what they do.
Post-deployment their support was very good. I would rate them a ten out of ten. They are very knowledgeable, not only about their product but about general DNS protocols, from performance to global interconnectivity. They were able to look at the whole picture and the small details within the picture as well.
Which solution did I use previously and why did I switch?
We switched from Akamai. It was slower and had fewer features.
How was the initial setup?
The initial setup was very straightforward. Using the migration itself was easy. The ongoing monitoring and change for the service, the support that we got from NS1, was all very clear. They are all very professional. There was no downtime. It's very, very straightforward. It took a few weeks. It was very short.
We kept a backup of the old service up and running, and moved 50% of the traffic into the new DNS and then into the new managed service. Then once we saw everything was running smoothly, we deployed the rest.
We were working with NS1's customer success team during our deployment. I was satisfied with their support.
What was our ROI?
We have seen better performance. It's very hard to measure if there is an ROI here, but we have absolutely seen better performance, and that is the important part for us.
Which other solutions did I evaluate?
We also looked at Neustar. NS1 solution has many more features and it works faster than any of the other solutions. It was also that the pricing was clearer and much easier to work with in terms of the tiers of the pricing. It was really the full package.
What other advice do I have?
For those who have a free cloud provider or basic DNS, I would say that the road into the application and the road into your infrastructure is part of the actual solution that you provide. DNS is part of that pavement. That is the road that end-users reach your application. The higher quality you can have there, especially if it's at a reasonable price means that you will be able to better serve your customers. And that is an important part of IT. Eventually, we are here to serve the business and if we can serve them better then it has an impact.
Once you have it side-by-side to your existing solution and the stability, speed, reduced error level, the easy connectivity into other platforms, observability, and automation are all worth the investment in engineering time and cost.
I would rate NS1 Managed DNS a ten out of ten.

Technical Lead - Production Engineer at a media company with 1,001-5,000 employees
Massively reduced DNS maintenance work for us, and provides good propagation times
Pros and Cons
- "The Filter Chain is one of the most valuable features, for geo-load balancing and geo-fencing. The Filter Chain is the most useful because it allows us to do several things. With geo-fencing we can redirect a particular user to a particular answer. That's very valuable for us. Filter Chains with monitoring is our strategy to provide redundancy."
- "The Filter Chain simulation is really good in the UI, but it would be nice to have something similar in the API so that we could simulate and test things before we deploy them."
What is our primary use case?
We use NS1 as the primary point of contact, the first point of contact for a client to reach us, to discover a DNS. We use NS1 in two ways: We use the Managed DNS product and the Dedicated DNS product, which gives us redundancy. Our primary use-case is for getting users to the CDN [content delivery network] one that is best suited for each user.
We have an automated deployment, so we use Terraform to deploy changes.
The managed solution is completely managed by NS1; it's not on-premises.
How has it helped my organization?
The integrations for monitoring events is helpful. Monitoring of events can change things in the Filter Chain. That helps our team receive alerts. Our team is kept in the loop about what is happening.
When it comes to maintaining uptime during a major DDoS attack, NS1 is very good. NS1's Dedicated DNS gives us redundancy. In addition, NS1 has worked closely with us to get us into the position we are in today. They do a good job in communicating problems and of looking forward with their solutions. They don't just address the current issue when it comes to DDoS and mitigation. These are continuous issues. It's not just a one-off that you handle once. They look for solutions that will solve future DDoS impact.
It has also improved our DNS response times. Because we have been using NS1 for quite a long time, it's hard to estimate how much response times have improved. But since we started with them we have definitely done better. The most critical thing that we look at, rather than the response time, is the time for propagation, and that's been very good.
The solution has also massively reduced DNS maintenance work in our company. The way we were set up a long time ago was that we would maintain things by ourselves, and now we don't do anything along those lines. For the external DNS, we do about 10 percent of the amount of work that we did previously. That's a huge improvement. The amount of maintenance has gone down significantly and our maintenance cost is down by at least 70 percent, for the external DNS.
NS1's automation has also enabled us to assign people to other kinds of work. It saves us time so that we can concentrate on other things.
Overall, it has helped to improve our end-user experience. Knowing the DNS delivery part is taken care of is important; performance is very critical. Taking users to the right CDN or data center is very important for the end-user experience. NS1 is part of the set of tools we have to achieve that better user experience and to get them to the right place.
What is most valuable?
The Filter Chain is one of the most valuable features, for geo-load balancing and geo-fencing. The Filter Chain is the most useful because it allows us to do several things. With geo-fencing we can redirect a particular user to a particular answer. That's very valuable for us. Filter Chains with monitoring is our strategy to provide redundancy.
We also use the automation extensively, with Terraform.
From the get-go, we have used the API from NS1. We have hardly used the solution's UI. For any major changes, we use the API and that works brilliantly for us. As an infrastructure team and organization, we heavily value infrastructure as code, so this is a great approach. Any feature that comes into the Filter Chain gets exposed first to the API, before it even goes to the human resources. It works very well and enables us to adapt a complete infrastructure-as-code approach.
The real-time telemetry and ecosystem of integrations were also a key part for us when choosing among multiple vendors, because of geo-location. It's very crucial for us. Choosing which server to use, in case of an emergency, for example, we depend on NS1's monitors. It's reliable and hasn't caused us any trouble. Another advantage is that there are multiple regions for the telemetry collections so, even if one of them has an issue, we are confident that there is enough redundancy to let us sail through the problem.
What needs improvement?
The Filter Chain simulation is really good in the UI, but it would be nice to have something similar in the API so that we could simulate and test things before we deploy them.
And while it's not exactly a problem, a nice-to-have would be a faster API. If we have to make a change to many things, it would be nice if there were a bulk change operation. For example, if we want to change TTL, we would just issue one bulk operation. We can make the calls simultaneously, but there are limits, even if you do things in parallel.
For how long have I used the solution?
I have been using NS1 Managed DNS in this company for about five years.
What do I think about the stability of the solution?
The stability has been very good. We haven't really had major problems. Especially, since we have the Dedicated DNS as well, our setup of NS1, as a whole, the Managed and the Dedicated, is very stable.
What do I think about the scalability of the solution?
We have confidence in NS1 that they will take care of our scaling needs. It's a hosted solution so we just send our traffic to them and, so far, there haven't been any issues.
The solution has helped us to meet SLAs and customers’ demands, without adding complexity. The scalability, when it comes to traffic, is very important because our traffic pattern changes. It's not a straight line on the graph. Scalability is a key feature for us.
How are customer service and technical support?
When we got started with Dedicated DNS, the technical support worked with us and they were really good and helpful.
How was the initial setup?
The initial was very simple and straightforward. Initially, sending the users to one of the data centers regions was the most complex part, but we had good help from support to understand Filter Chains and to set things up correctly. The process didn't take too long.
We didn't have any downtime when migrating to NS1 because we had external DNS as well.
What about the implementation team?
Our experience with the NS1 customer success team has been good. We have worked closely with them on many occasions. Some of the problems were even new to them, because we had unique features. They were happy to engage and bring in people from their core engineering teams to help. It has been really nice working with NS1's customer success teams. That's one of the biggest advantages of NS1.
What was our ROI?
I believe we have seen ROI, and that's why we keep going back to them. We've been using them for five years and that is a long time. It's useful for us and it delivers.
Which other solutions did I evaluate?
We recently evaluated another solution, but the complexity involved with it was slightly high. With NS1, our Filter Chain is cleaner. Also, scaling would add a complexity factor with the other solution.
If someone says they can use a basic DNS, one issue is that it only works to a certain scale. After a certain limit you will have to pay exponentially more. You need to be aware of up to what scale a solution will work for you. Another issue to consider is the flexibility. An enterprise solution has features, such as the Filter Chain, to do complex things, and they might not be available in the free solutions. A third factor is support. That is one of the key features in evaluating these solutions, especially if you're building a product that is critical for a customer. I'm not sure that the free solutions provide that level of support. All of these factors are very good with NS1.
What other advice do I have?
Engage as much as you can with their customer success team. Explain your use cases very well and they will suggest good solutions that are the perfect fit. Keep in touch with their team. NS1 is an evolving product. The more you stay in touch with the customer success and technical support teams, the more likely it is you will be successful.
Also, focus on automation. NS1 is API-driven. The fact that we are really focused on and invested in automation tools has really helped us.
