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 is a fast and secure DNS."
"The features of Cloudflare were found to be more beneficial and led to the decision to utilize it over other options."
"The solution is very good at mitigating threats."
"The solution offers the flexibility to control configuration rules."
"The most valuable feature of Cloudflare is the GUI. You are able to control the solution very well through the interface. There is a lot of functionality that is embedded in the service."
"Smaller businesses have seen great ROI due to the low investment and strong performance."
"The tool is user-friendly."
"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."
"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 important aspect, in general, is that the price is suitable for most clients."
"The DDoS protection features are valuable."
"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."
"It is a good solution. Its vendor support is the most valuable. It is simple and works well if you have Juniper MX routers."
"This is a hybrid solution."
"SmartWall devices occupy only one-fourth of the width of a rack unit, making them very easy to install."
"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."
"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."
"Kentik excels in telemetry within data centers and works well in multi-vendor environments."
"Overall, the ease of use and the fact that it meets client expectations are major positives."
"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."
"It offers a simple yet powerful feature of classifying applications, going beyond basic statistics."
"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."
"We're pretty happy with the API functionality. It's web, and it's very simple to set up queries. It has served us well and you don't need to be an expert on the API or the product to set these things up."
 

Cons

"It should have easier documentation for the configuration. It's very technical and people who aren't technical should also be able to do the configuration."
"For the free and Pro plans, Cloudflare could use a simple bot to provide information to users. This would improve support, especially for less advanced users who utilize the free components."
"Technical support is lacking."
"They lack a good way to manage DNS as a company, since everything is relegated to single account logins until you get to the higher levels. They have come out with a paid feature to remedy this, but I have not had a chance to fully review it yet to know if it fixes the access problem."
"Cloudflare should add more documentation and pricing to the cloud version."
"Eventually, things go sideways and require fixes when it would have been easier to prevent the issue initially."
"There could be more courses with engineers. I like e-learning, however, having a specialist in a classroom is more comfortable for me."
"Cloudflare could be improved by introducing a mid-tier pricing option."
"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."
"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."
"The product must provide more Layer 7 capabilities."
"Lacks international presence."
"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..."
"The product could strive for more improvements to become closer to perfect."
"We asked for a way, regarding the potential networks that exist, to hook Kentik up with external tools like peering DBs to correlate things together and see what we can do... This is all in the [next] beta now."
"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."
"I consider the pricing model as an area for improvement."
"I believe they're already working on this, but I would love for them to create better integrations from network flow data to application performance — tracing — so that we could overlay that data more readily. With more companies going hybrid, flow logs and flow data, whether it be VPC or on-prem, matched with application performance and trace data, is pretty important."
 

Pricing and Cost Advice

"The pricing for the service is reasonable, neither excessively cheap nor prohibitively expensive. It aligns well with the value of their solution."
"A free version of the solution is available."
"The cost primarily depends on the size of the organization."
"The product's pricing is minimal compared to other products."
"That is one of the great features. I was able to access the majority of the features and services for free."
"We are using the free version."
"Cloudflare's pricing is not much higher and is good for middle-level organizations."
"The price is reasonable."
"The price of Corero is affordable."
"Its price is normal."
"The tool is cheaply priced."
"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."
