Helps deal with DNS DoS attacks and corrupt DNS requests

I know my company does come across problems related to the product, sometimes related to a configuration issue or a bug. My company receives good support from EfficientIP DNS Guardian's team, who are responsible and passionate about the product. As far as I know, all of my company's challenges and issues have been successfully resolved. I can't think of any weaknesses or issues which I would like to highlight in a significant manner. EfficientIP DNS Guardian has a certain default behavior that didn't meet our company's requirements. After the consultation with EfficientIP DNS Guardian's IT support, a configuration changed the product's default behavior, which was undesirable for us, to a desirable behavior. Certain issues happen in every product.

Smart routing has improved uptime and performance and enables real-time automated traffic control

The best features IBM NS1 Connect offers, in my opinion, are real-time monitoring, intelligent traffic routing capabilities, and being API driven. The intelligent traffic routing and API-driven features of IBM NS1 Connect have helped my team by allowing routing based on user location, endpoint switching based on latency, and DNS response time. Additionally, IBM NS1 Connect has API integration. IBM NS1 Connect positively impacts my organization by making our website load faster and enhancing the user interface to be more intuitive and user-friendly. It's very economical and cost-effective. I also love it because it saves time through automation, saving around 30% to 35% of our time and also saving man-source. Our application uptime has improved by 40% to 45%. Although there have been a few outages, the service uptime has significantly improved our trust with clients. It is very cost-effective and affordable, hence providing a great return on investment.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"The most valuable feature of the solution is DNS security."

"It is a very stable solution. Stability-wise, I rate the solution a ten out of ten."

"You can run a DNS server directly from EfficientIP to help mitigate all DNS attacks from various sources. This is a very good feature."

"This product is very stable."

"The solution's stability is absolutely perfect."

"I couldn't recommend a better product than NS1 for managed DNS and CDN load balancing right now."

"From a maintenance standpoint, mainly in terms of maintenance provisioning and deprovisioning, since we do not really see the internals of the SaaS solution, the reduction would be drastic, and it would be a tenth of the time."

"NS1 was the first solution that could express the logic we needed to be hidden behind the records, and we couldn't adapt any other solution to our needs."

"Going with NS1 has also improved the user experience for our users."

"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."

"IBM NS1 Connect has positively impacted my organization by providing controlled downtime, reduced downtime, and time saving through automation, as approximately forty to fifty percent of our time is saved through automation and enhanced visibility."

"NS1 solution has many more features and it works faster than any of the other solutions."

Cons

"EfficientIP DNS Guardian has a certain default behavior that didn't meet our company's requirements."

"EfficientIP DNS Guardian's deployment documentation is very hard to find. The tech support's response is slow."

"The problem with this vendor is that they are too focused on revenue and sales numbers."

"We use the geo load balancing functionality and there are a couple of things that are helpful there. But the language itself is something we had to get used to a little bit. Some of my folks made a few mistakes in rolling out the Filter Chain...The Filter Chain setup is a bit hard to grasp at first. It would also be nice to have a way to simulate changes in addition to staging."

"We would really like them to become a DNS registrar."

"The reporting metrics are great from an API standpoint, but it would be a little bit nicer if there was some type of dashboard around that. There should also be some type of reporting that's more executive-level focused."

"The Filter Chain setup is a bit hard to grasp at first."

"I believe IBM NS1 Connect can be improved in several ways. The main concern I identified is the cost, which is higher than other solutions despite its uses."

"When we first deployed, we flipped the switch, and it didn't work as well as we expected."

"The technical support is slow. You raise a PR, and then it takes several weeks for them to respond."

"When we first deployed, we flipped the switch, and it didn't work as well as we expected. It wasn't a complete outage, but we had issues in some places with some customers. The NS1 team went out of their way to resolve it on Thanksgiving. We have a post about it on our blog. We called it "Black Thursday.""

Pricing and Cost Advice

"The solution is subscription-based."

"The price of this product is very reasonable, especially considering that a company's reputation is priceless."

"I rate the product price as three to four on a scale of one to ten, where one is low cost, and ten is high price."

"We pay about $30,000 a month. We used to pay about $20,000 with Dyn every month, for lower volume than we're doing right now, but it had none of the features that we have available with NS1, so it was worth it for us. It seems competitive for us, given that we're doing 4.5 billion requests."

"Everything can always be cheaper, but as it is today the pricing is fair."

"From a cost standpoint, it's certainly not the most expensive out there, and it's also not the cheapest, but it does well to balance the cost and the functionality/reliability."

"The cost of this product is one of the reasons that we chose it."

"NS1's pricing is much more aggressive than its competitors in the market and you get more value out of what you pay for it."
