It's easy to set up because you point the DNS to it, and it's working in under 15 minutes
Cloudflare is highly scalable. Cloudflare is a system with a web portal that the end users like me see. It's a console where we can adjust the DNS, caching, and security features all in that console. Cloudflare owns thousands of servers across the world that cache the data. It's a powerful solution. When clients sign up for Cloudflare, they're getting this monster content delivery network, security, and a web application firewall in one. It's all rolled into one, and it's massive. Unless you have your website hosted on a massive hosting provider, there's no way that you can deliver the amount of data that Cloudflare can provide to the end users. If you have static content, there's no way that you can ever match what Cloudflare can do. Obviously, there are competitors to Cloudflare that do the same, but I'm saying other types of solutions. Let's say you go with F5. Great, that's on-prem. That's in your colo. You can't deliver as much data to the internet as you can with a CDN. You don't have to spend $20,000 on a net scaler, F5, or whatever Cisco's selling now. You don't have to buy that. You pay them $50 a month or $150 a month. It's totally worth it because even in five years, you'll never get the performance value, not just the actual ROI. You have to consider how much throughput you can get with Cloudflare.

Rapid attack detection and traffic visibility improve security management
The solution was intended for the big clients of Telefonica to clean their internet pipe. We deployed the service to clean the pipe. In some clients' data centers, we implemented a solution that detects and mitigates attacks using Arbor DDoS, our data center solution For me, the most valuable…

Effect local attack handling, intuitive interface, and scalable
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.

Quotes from Members

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

Pros

"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."
"Cloudflare has many features."
"The DDoS protection is the most valuable aspect of the solution."
"Cloudflare allows us to self-host services such as Rocket.Chat and Node-RED, in high-availability mode, thanks to round robin DNS which allows us to share one hostname between our two locations."
"The most valuable features of the solution are performance and security."
"The most valuable feature of Cloudflare DNS is security."
"The features of Cloudflare were found to be more beneficial and led to the decision to utilize it over other options."
"Cloudflare offers CDN and DDoS protection. We have the front end, API, and database in how you structure applications."
"I recommend using Arbor DDoS for those wanting to keep their services online."
"Our customers are very happy when we provide them with the interface... They can check how many attacks they have faced and how many attacks have been blocked."
"It is fully mitigating the attacks. We've dealt with other ones where we didn't necessarily see that. The detection is very good. It's also very simple to use. Arbor is a single pane of glass, whereas with other solutions you might have a detection pane of glass and then have to go to a separate interface to deal with the mitigation. That single pane of glass makes it much simpler."
"The product allows us to check real-time progress, including latency and network activities."
"Arbor has the ability to learn and self-create the appropriate profile for each customer."
"The technical support of Arbor DDoS is good."
"In the GUI, the packet capture is a very good option, as is the option to block an IP address."
"Reporting is quite good. There are several pages of reporting on DDoS attacks, and you can find all the details that you need."
"The most important aspect, in general, is that the price is suitable for most clients."
"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."
"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 DDoS protection features are valuable."
"SmartWall devices occupy only one-fourth of the width of a rack unit, making them very easy to install."
 

Cons

"We have noticed multiple instances where Cloudflare falsely indicates that our servers are down, even when there is no actual load on them. This makes it challenging for us to identify the exact issue."
"It would be helpful if the solution could continue evolving to compete with the other solutions on the market."
"The product support needs to be accessible from more places, a wider area of coverage."
"The solution could work at being less expensive. It costs a lot to use it."
"Sometimes their more advanced caching tools can cause higher first-byte times and problems with JavaScript."
"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."
"The integration of LLMs on the dashboard is something that is needed in the tool."
"The upgrade process is mildly complex requiring treatment of the custom embedded OS separately from the application. The correlation of the underling OS to the application version can be easily missed."
"The product could have end-to-end platform visibility."
"The solution's IT support needs improvement."
"It could include a lot of enhancements related to AI and automation."
"The implementation should be made easier."
"An improvement to Arbor DDoS would be to make evaluation licenses and virtual machines available."
"Real-case scenarios that have taken too long to resolve or were escalated can be directly converted into articles."
"There should be an automatic way to configure it to monitor traffic and decide which is an attack and which is not. In Arbor, you need to tweak and set all parameters manually, whereas in Check Point DDoS Protector, you can select the lowest parameters, and over the weeks, Check Point DDoS Protector will learn the traffic and you can then tighten some of the parameters to decide which traffic is regular and which is malicious."
"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."
"Lacks international presence."
"The product must provide more Layer 7 capabilities."
"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."
"It could use support in Spanish."
 

Pricing and Cost Advice

"So far I use free tier and happy with it. You can subscribe to business package if needed."
"For Cloudflare, I recommend it heavily for small businesses with revenue under a couple of million dollars. Onboarding is easy, and they even have a free plan. This makes it simple for businesses in the $100,000-$500,000 range to try it out and see its value, allowing them to scale up their infrastructure as needed."
"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."
"We are using the free version."
"Cloudflare's pricing is not much higher and is good for middle-level organizations."
"The pricing depends on the usage, but the cheapest would be around 5,000 USD a month."
"The cost primarily depends on the size of the organization."
"The price of the solution is expensive."
"There is room for improvement with the pricing. It is an expensive solution. The issue with the pricing is more the way it is built. Right now we're paying per router, and there's a limitation there. I would like to see bundle-pricing where there is an overall solution cost."
"The pricing of the solution is cheap."
"The solution's pricing is based on a licensing model that is expensive when compared to other tools."
"The price is a little high."
"Arbor's products are very expensive. Their competitors are cheap when compared with Arbor."
"I don't deal with the pricing, but it seems that you need to get basic support in order to upgrade the software and implement some patches."
"Because the solutions from competitors are very different, it's not easy to compare. However, the licensing from Arbor is clear and understandable and the pricing is reasonable when looking at the market, in general."
"As far as I know, they are the best in this sector, in DDoS protection. They know it, I know, because their service prices are too high. They provide cloud DDoS protection for ISPs, but that is also too expensive."
"Its price is normal."
"The price of Corero is affordable."
