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…

An easy-to-use tool with great GUI
The product's initial setup phase was really easy. There is a lot of time involved in the testing phase and other processes related to the area of deployment, so it may take up to two weeks to deploy the solution. The solution is deployed on an on-premises model. One person is enough to take care of the deployment phase of the product. The person involved in the deployment phase needs to better understand topologies when dealing with Fortinet.

Quotes from Members

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

Pros

"New and innovative way to protect the client's data."
"I like Cloudflare's application gateway and DDoS protection."
"The features of Cloudflare were found to be more beneficial and led to the decision to utilize it over other options."
"Centralized, full-featured DNS."
"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."
"The most valuable feature of Cloudflare DNS is its global reach and it is always evolving."
"Cloudflare has many features."
"The most valuable features of the solution are performance and security."
"Arbor DDoS's best feature is that we can put the certificates in, and it will look at layer seven and the encrypted traffic and do the required signaling."
"I recommend using Arbor DDoS for those wanting to keep their services online."
"The stability is okay and we have not encountered problems with the solution."
"It's just one dashboard with mitigation. You decide which mitigation you want and at what threshold to do this or that. Its operation is pretty simple. It's easy."
"The solution provides good protection against volumetric DDoS attacks."
"Its scalability is big. It is for large deployments of big organizations and service providers."
"The stateless device format means that the box is very strong for preventing DDoS attacks."
"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."
"Packet inspection has been effective for mitigating DDoS attacks."
"The product's initial setup phase was really easy."
"The equipment works very well, and I have not encountered any issues with it."
"This solution can protect Layer 3, Layer 4 and Layer 7 attacks of applications for us."
"I find the interface easy to use."
"The equipment works very well, and I have not encountered any issues with it. It is a good solution for my company."
"The product allows the users to adjust the thresholds."
"The protection resources and the support are valuable features of the solution."
 

Cons

"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."
"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."
"I would like Cloudflare to offer a dedicated account manager for large enterprise clients like us."
"The product support needs to be accessible from more places, a wider area of coverage."
"Cloudflare doesn't have a reverse lookup. We can only do a DNS lookup to get the IP address from the hostname. It doesn't work if you want to look up the hostname from an IPA address."
"Cloudflare could offer a better view or maybe dashboards of the main resources used in the client."
"We're facing challenges due to an upgrade in the machine learning model. The problem arises from some users abusing the APIs, resulting in an influx of suspicious traffic. Cloudflare's learning model mistakenly identifies this traffic as human. Consequently, it assigns it a higher trust score, akin to legitimate human traffic, causing complications in our architecture. Previously, such traffic would have been categorized as suspicious, enabling us to apply appropriate blocking rules. However, we encounter difficulties distinguishing between genuine and suspicious traffic with the new categorization. Despite these challenges, overall, Cloudflare remains the preferred solution compared to Azure, AWS CloudFront, and Google Cloud Armor."
"I think Arbor DDoS needs improvement in areas where competitors like S5, Redver, or NETSCOUT offer web application firewall functionality or dedicated web application firewall devices. Arbor lacks these features, which is a significant disadvantage. Yes, I would like to see these features introduced in Arbor as well. Regarding real-time detection capabilities, Arbor DDoS works very well. We and our customers are very satisfied with its performance. However, it would benefit from adding Web Application Firewall (WAF) capabilities to reach a larger customer base."
"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 look and feel of the management console is a little old, excessively simple. If you compare it with other solutions, the look and feel of the console is like you're using technology from five or six years ago. It doesn't show all the technology that is actually behind it. It looks like an older solution, even though it is not."
"There is definitely room for improvement in third-party intelligence and integrations."
"Real-case scenarios that have taken too long to resolve or were escalated can be directly converted into articles."
"It could include a lot of enhancements related to AI and automation."
"The implementation should be made easier."
"They should improve the reporting section and make it a little bit more detailed. I would like to have much better and more detailed reports."
"The only thing they need to do is to automate it. Today, you must create tools that do not require the use of an expert or anyone with special skills."
"The product’s pricing needs improvement."
"All the thresholds that need to be configured should be included in the default so that user will not forget or misconfigure."
"The solution can be a little more user-friendly and it can be more affordable."
"The main improvement would be to change the firewall model, however, currently, everything is fixed and working well."
"I would like to see analytics, big data."
"Alerts and reporting features must be improved."
"The primary area for improvement is the on-premises capacity limit, currently fixed at 10 GB."
 

Pricing and Cost Advice

"So far I use free tier and happy with it. You can subscribe to business package if needed."
"A free version of the solution is available."
"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."
"In terms of licensing costs, we don't pay for licensing for Cloudflare. We only establish communication, then for peering, Cloudflare takes care of the cross-connection in different data centers."
"Cloudflare's pricing is not much higher and is good for middle-level organizations."
"We don't have any issues with the price."
"The cost primarily depends on the size of the organization."
"The solution is expensive when compared to other products but offers unlimited bandwidth."
"Arbor's products are very expensive. Their competitors are cheap when compared with Arbor."
"The licensing of a complete Arbor solution, including fire-walling and unified site management, can get expensive."
"The price of this solution is a little high in the African market, it should be lower."
"Our customers always complain about the price of the product."
"The price of Arbor DDoS depends on many parameters. It depends on the physical capacity of the environment, and it is not a straight-line price. It's fairly competitive in the market on the price."
"The solution is a bit costly if you're a small organization, but I think it's worth the price that they are charging."
"Start with a small license. Measure your bandwidth requirements."
"The pricing of the solution is cheap."
"The product’s pricing needs improvement."
