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…

Identifies a request that comes up multiple times, block holds that particular IP, and lets the genuine traffic pass through
Genuine traffic coming in is still getting better. While I understand that it's some sort of algorithm that is written in this scale, that algorithm can be a little bit better because sometimes while we are doing DDoS mitigation, genuine traffic does get blocked. While it is one of the greatest features it can still be improved. I would like to see a dashboard that shows you the data that is transferred from which end. It's where people start looking at abuse management. People keep questioning when the mitigation is on what service it is and how many GBs are passing through. An end user dashboard that will help you identify all of these questions and that can be visible in your entire organization is something that would make sense.

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 DDoS protection is the most valuable aspect of the solution."
"The solution is stable, and the DNS servers are simple to use."
"The most valuable feature of the solution is external DNS. It is also very secure. They have their own main server and once you configure it, the product takes care of everything. There are no issues in resolving IPs and low latency is also present."
"From what I've seen so far, there are no negatives to report as of yet"
"The most valuable feature of Cloudflare DNS is its global reach and it is always evolving."
"The technical support is good."
"I get a lot of value from Cloudflare's API because it enables you to build a separate environment inside the solution. You can create a domain for performing test requests before you move to the production environment and connect various domains."
"The stateless device format means that the box is very strong for preventing DDoS attacks."
"The most valuable feature is mitigation, which can blackhole the IP."
"The solution is easy to use."
"We can reduce the bandwidth to minimize the attack level. If we see more than 2.5 GBs we drop it directly."
"I like all the features together as a whole."
"Arbor has a global ranking in reliability and credibility. They are very unique and can respond to a very wide scope of threats from their global deployment."
"The quality of the technical support provided by Arbor DDoS is premium."
"The most valuable features include the traffic categorization and control of the traffic. The filtering of the traffic is very precise. When you want to stop some traffic, you precisely stop that traffic."
"In the DDoS it's difficult to validate what is a genuine request from an end user. We've started being able to do that with the logistics that they have set up. With the protection that they have provided, they are able to identify what is valid and what is not valid. We see that a person who is getting DDoS Neustar service is able to block that particular user. However, while they are doing that it doesn't affect other customers on the server."
 

Cons

"Although I think it's quite good, it doesn't provide me with all the features I would expect to have if I were using Imperva."
"It would be beneficial for us if Cloudflare could offer a scrubbing solution. This would involve taking a snapshot of my website and keeping it live during a DDoS attack, ensuring uninterrupted service for our users. DDoS attacks are typically short in duration, and having Cloudflare maintain the site's availability from its secure network would enhance the overall user experience. I would appreciate it if Cloudflare could consider implementing this feature. Many organizations already utilize similar capabilities in their CDN platforms, where a static snapshot of the web page is displayed during DDoS attacks. In terms of features, Cloudflare needs to enhance its resilience and stay more focused on adopting new technologies. For instance, solutions like F5 XC Box, Access Solution, and Distributed Cloud Solution have impressive features, and Cloudflare should strive to match and exceed those capabilities. There's a need for improvement in areas like AI-based DDoS attacks and Layer 7 WAF features. Cloudflare should prioritize enhancements in areas such as behavioral DDoS and protection against SQL injection attacks, considering the prevalent trend of public exposure to the internet for business reasons. Overall, Cloudflare needs to invest more in advancing its feature set."
"The integration of LLMs on the dashboard is something that is needed in the tool."
"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."
"It should confirm audit findings of the assigned area with auditees to ensure that the audit conclusions are based on an accurate understanding of the issues."
"I would like Cloudflare to offer a dedicated account manager for large enterprise clients like us."
"Cloudflare's console should be made more user-friendly."
"Latencies are always a problem."
"On the application layer, they could have a better distributed traffic flow. They could improve that a bit. For network data it is very effective, but the application layer can be improved."
"The regional support here in African could improve, such as marketing and account managers."
"Support in Argentina is not so good. Although the team is good, they are not fast, and they lack the skills to manage dynamic attackers."
"An improvement would be to provide information on how pricing is done on different customer levels."
"It could include a lot of enhancements related to AI and automation."
"I would also like more visibility into their bad actor feeds, their fingerprint feeds. We try to be good stewards of the internet, so if there are attacks, or bad actors within our networks, if there were an easier way for us to find them, we could stop them from doing their malicious activity, and at the same time save money."
"An issue which needs to be addressed concerns information I received of attacks on the radar and Arbor, allegedly, not taking any action."
"Auto mitigation is a feature provided when DDoS is observed on any of link/customer (configured under auto mitigation). It automatically starts mitigation with default filters. In default filter mode, there could be an impact on the customer’s link,"
"I would like to see a dashboard that shows you the data that is transferred from which end. It's where people start looking at abuse management. People keep questioning when the mitigation is on what service it is and how many GBs are passing through. An end user dashboard that will help you identify all of these questions and that can be visible in your entire organization is something that would make sense."
 

Pricing and Cost Advice

"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."
"The cost primarily depends on the size of the organization."
"We don't have any issues with the price."
"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 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."
"The tool is a premium product, so it is very expensive."
"Regarding pricing, I would rate it as average. Arbor DDoS offers good value for money with our DDoS filter device. For higher protection needs, Arbor’s CloudMeter’s DDoS mitigation or hardware devices might be more expensive, but customers who need them are usually prepared for the cost and the additional resources required."
"The price is a little high."
"The pricing of the solution is cheap."
"The solution is a bit costly if you're a small organization, but I think it's worth the price that they are charging."
"I believe that the price of Arbor DDoS falls under the bracket of medium to high price."
"Start with a small license. Measure your bandwidth requirements."
"The price of this solution is a little high in the African market, it should be lower."
"Arbor DDoS is quite expensive, but all these solutions are expensive because they deal with confidential information."
