Carlos Alam Hernandez Baruch - PeerSpot reviewer
Fast and secure deployments simplify operations for government and fintech clients
It is a fast and secure DNS. It is very easy to deploy, and my customers are happy with this tool. Additionally, the CDN performance in Mexico is excellent, providing fast service and tools. It offers reliability during high-traffic periods, ensuring no impact on the environment. It helps my clients avoid using on-premise boxes, simplifying operations as they only use the prices on Cloudflare.
Björn Lindman - PeerSpot reviewer
The product is highly stable and has valuable features, but it must provide more Layer 7 capabilities
We use the solution for DDoS protection in the routers The DDoS protection features are valuable. The product must provide more Layer 7 capabilities. It must provide deep inspection features. I have been using the solution for ten years. The tool has high stability. I rate the stability a nine…

Client experience and cybersecurity have improved with an easy setup
The solution is valuable for client experience, especially in the financial sector. The most important feature is cybersecurity. The pricing is good, but the functionality is the most important aspect for clients. The solution is easy to deploy and requires only one person to set up, making it easy and quick. Overall, the ease of use and the fact that it meets client expectations are major positives.

Quotes from Members

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

Pros

"It's very user-friendly."
"The solution provides good load balancing and protection against DDoS attacks."
"Cloudflare DNS is widely used, and it's good for websites. If we use Cloudflare DNS and update one record, it updates in their office instantly."
"Its ease of integration with Office 365 and the fact that it's a good product compared to what I had before"
"Its most significant benefit to date is the speed with which it refreshes DNS records on the internet once you change it. If you are changing a website or registering a new record, it is very quick."
"The most valuable features of the solution are performance and security."
"The overall experience with Cloudflare is positive, with a rating of eight out of ten."
"The solution automatically detects and responds to certain types of traffic based on geolocation."
"The most important aspect, in general, is that the price is suitable for most clients."
"It is a good solution. Its vendor support is the most valuable. It is simple and works well if you have Juniper MX routers."
"The DDoS protection features are valuable."
"This is a hybrid solution."
"SmartWall devices occupy only one-fourth of the width of a rack unit, making them very easy to install."
"It is an agnostic and transparent inline platform, which means that the maximum visibility of the symmetric and asymmetric traffic is available, even allowing bidirectional detection of the attack."
"The most valuable feature of Corero is its ability to handle smaller attacks in terms of the amount of volume and time. You can handle almost 100 perfect of the attacks locally."
"Kentik excels in telemetry within data centers and works well in multi-vendor environments."
"I am able to do a lot of work on the visualization end to create different visualizations and different ways to get information out of it."
"We're also using Kentik to ingest metrics. It's a useful feature, and its response time, whenever we're pulling back the data, is higher than our on-prem solution."
"Overall, the ease of use and the fact that it meets client expectations are major positives."
"The most valuable feature is being able to pull traffic patterns; to and from destinations. We're able to understand where our traffic is going, our top talkers from an AS set, as well as where our traffic's coming from."
"The most valuable features have been anything around traffic engineering: being able to determine the source or destination of a surge of traffic, whether it's DDoS-related, or a customer just happened to have a sudden uptick in traffic. Being able to tell where that's coming from or where it's going to enables us to do things based on that."
"The drill-down into detailed views of network activity helps to quickly pinpoint locations and causes. All the information is there."
"One of the valuable features is the intuitive nature of building out reports, and then triggering actions based on specific metrics from those reports. It has a really good UI and the ability to surface data through the reporting functions is pretty good. That's helped a lot in the security space."
 

Cons

"It would be good if Cloudflare could have more servers for better traffic routing or an increase in the traffic routed. This is what I'd like to improve in Cloudflare."
"I believe they currently have this feature, but there will most likely be integration with APIs so we can control some features through API."
"Technical support is not well developed. While there are good engineers, Cloudflare does not offer hands-on technical support to fix customer problems but rather a self-service model."
"There could be more courses with engineers. I like e-learning, however, having a specialist in a classroom is more comfortable for me."
"The solution could work at being less expensive. It costs a lot to use it."
"Areas like how assessment, discovery, and payload are dealt with and how it all comes into your organization can be considered when trying to make suggestions to Cloudflare for improvements."
"The product support needs to be accessible from more places, a wider area of coverage."
"Cloudflare does not have an on-premise solution. If they had different approaches they could be better suited to accommodate more customers, such as on-premise and hybrid deployments. For example, hybrid deployments would be useful where you could move the traffic from the enterprise to the cloud."
"The product must provide more Layer 7 capabilities."
"It could use support in Spanish."
"The approach taken by Corero is to partner with other organizations in order to address volumetric attacks that cannot be handled by the hardware installed in the infrastructure. Corero does not have a solution for these attacks, so they are looking for partners to help them manage them. This approach is supplemented by local hardware, but the main focus is on the partnerships. It would be beneficial to have a more complete solution."
"Corero needs to improve its application DDoS prevention capabilities and user behavior detection features."
"Lacks international presence."
"Juniper is known in our country, but it is not very popular. There is also not enough information about Corero. Our enterprise and financial sectors don't know about this solution. They need to provide more information and do more marketing for this solution in our country."
"The only downside to Kentik, something that I don't like, is that it's great that it shows you where these anomalies lie, but it's not actionable. Kentik is valuable, don't get me wrong, but if it had an actionable piece to it..."
"I would like to see them explore the area of cost analysis."
"Sometimes, the tool has complications, so we must deal with the additional support from the tool's end."
"We had faced some issues during an outage and were not able to get the desired results from Kentik tools. It took time to resolve these issues, which is why I give them eight points."
"There is room for improvement around the usability of the API. It's a hugely complex task to call it and you need a lot of backing to be able to do it. I should say, as someone who's not in networking, maybe it's easier for people who are in networking, but for me that one part is not very user-friendly."
"I consider the pricing model as an area for improvement."
"In recent months, I've noticed that while the industry is trending towards AI, Kentik has room for improvement in this area."
"They're moving more in a direction where they are saying, "Hey, here's information that you may be interested in or may a need," before the question has to explicitly be asked. Continuing to move in that direction would be a good thing."
 

Pricing and Cost Advice

"Cloudflare's pricing is not much higher and is good for middle-level organizations."
"The pricing for the service is reasonable, neither excessively cheap nor prohibitively expensive. It aligns well with the value of their solution."
"The price is reasonable."
"The tool is a premium product, so it is very expensive."
"When you compare Cloudflare DNS to other solutions, such as Akamai, the price is reasonable."
"I think the pricing is competitive. I think as far as licensing is concerned it's pretty straightforward because it's based on domain. It's just that sometimes domains could be tricky with some customers."
"A free version of the solution is available."
"The solution is expensive when compared to other products but offers unlimited bandwidth."
"Its price is normal."
"The price of Corero is affordable."
"We have an annual contract with Kentik that we renew each year for a set number of licenses. We also have some burstable licenses which we can spin up and spin down, and those are paid as they are used."
"The tool is cheaply priced."
