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

"The features of Cloudflare were found to be more beneficial and led to the decision to utilize it over other options."
"We're using dynamic components to build flexible pages to create and manage Git merge requests for code and reviews."
"Cloudflare consolidates various capabilities into one product, streamlining processes."
"Centralized, full-featured DNS."
"I like Cloudflare's application gateway and DDoS protection."
"The most valuable feature is its usability."
"The UI is good."
"From what I've seen so far, there are no negatives to report as of yet"
"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."
"The most important aspect, in general, is that the price is suitable for most clients."
"The DDoS protection features are valuable."
"SmartWall devices occupy only one-fourth of the width of a rack unit, making them very easy to install."
"It is a good solution. Its vendor support is the most valuable. It is simple and works well if you have Juniper MX routers."
"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."
"This is a hybrid solution."
"Kentik excels in telemetry within data centers and works well in multi-vendor environments."
"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."
"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."
"Having the API access allows us to do a great deal of automation around a lot of our reporting and management tools."
"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."
"The most important feature is cybersecurity."
"The drill-down into detailed views of network activity helps to quickly pinpoint locations and causes. All the information is there."
"Overall, the ease of use and the fact that it meets client expectations are major positives."
 

Cons

"I would like Cloudflare to offer a dedicated account manager for large enterprise clients like us."
"The Cloudflare load balancing capability hasn't really helped in enhancing my website's uptime and resiliency because we don't really get that much traffic; it's mostly remote users, and web hosting is done by a web hosting service."
"The integration of LLMs on the dashboard is something that is needed in the tool."
"I think the APIs are a little bit hard for us to work with. The APIs could be more open so that we could integrate better with our SolarWinds or our monitoring solution."
"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."
"DNS Management."
"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."
"It should be easier to collect the logs with companies like Sumo. However, based on my discussions with the salespeople, I understand that's how they make their money. With the enterprise product, they want people doing those kinds of enterprise features to do the logging. They want them to pay a lot of money, and that's where I have an issue with them. That should be a default. You should be able to get the log no matter what. The logging should be universal."
"Corero needs to improve its application DDoS prevention capabilities and user behavior detection features."
"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."
"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 product must provide more Layer 7 capabilities."
"It could use support in Spanish."
"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 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."
"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 would like to see them explore the area of cost analysis."
"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."
"In recent months, I've noticed that while the industry is trending towards AI, Kentik has room for improvement in this area."
"Sometimes, the tool has complications, so we must deal with the additional support from the tool's end."
 

Pricing and Cost Advice

"The solution has many features but there are ones that you need to pay for. Sometimes you have to find out which is available for free and which you have to pay for."
"The pricing for the service is reasonable, neither excessively cheap nor prohibitively expensive. It aligns well with the value of their solution."
"The pricing depends on the usage, but the cheapest would be around 5,000 USD a month."
"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."
"So far I use free tier and happy with it. You can subscribe to business package if needed."
"We are using the free version."
"It's a premium model. You can start at zero and work your way up to the enterprise model, which has a very high pricing level."
"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."
