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.

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

"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."

"It is a stable solution. I rate the stability a ten out of ten...I rate the scalability a ten out of ten."

"The most valuable features of the solution are performance and security."

"Cloudflare is a security SaaS provider that provides security and protects us from any application layer attack."

"The tool is user-friendly."

"The most valuable feature of Cloudflare DNS is its global reach and it is always evolving."

"The solution automatically detects and responds to certain types of traffic based on geolocation."

"The solution is stable, and the DNS servers are simple to use."

More Cloudflare pros

"This is a hybrid solution."

"The most important aspect, in general, is that the price is suitable for most clients."

"SmartWall devices occupy only one-fourth of the width of a rack unit, making them very easy to install."

"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 DDoS protection features are valuable."

"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."

"The solution is very user-friendly and very 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."

"We have researched them all, and it's a good solution all around."

"The protection resources and the support are valuable features of the solution."

"The most valuable feature is the cloud DDoS scrubbing capability."

"It is a user-friendly product in terms of monitoring and updating policies."

"Packet inspection has been effective for mitigating DDoS attacks."

"The product allows the users to adjust the thresholds."

More Fortinet FortiDDoS pros

Cons

"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."

"Cloudflare could be improved by introducing a mid-tier pricing option."

"The product support needs to be accessible from more places, a wider area of coverage."

"In the last two years, there has been a certain amount of downtime when using the VDM."

"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."

"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."

"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."

More Cloudflare cons

"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."

"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."

"Lacks international presence."

"It could use support in Spanish."

"The tool needs to focus more on the area of application traffic management, where it currently has some shortcomings."

"There aren't really any aspects of the solution we are unhappy with. It's been a positive experience overall."

"The main improvement would be to change the firewall model, however, currently, everything is fixed and working well."

"All the thresholds that need to be configured should be included in the default so that user will not forget or misconfigure."

"The primary area for improvement is the on-premises capacity limit, currently fixed at 10 GB."

"I find that there have been issues in the past year with the solution hanging. It freezes often."

"Alerts and reporting features must be improved."

"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."

More Fortinet FortiDDoS cons

Pricing and Cost Advice

"The pricing depends on the usage, but the cheapest would be around 5,000 USD a month."

"The pricing for the service is reasonable, neither excessively cheap nor prohibitively expensive. It aligns well with the value of their solution."

"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 don't have any issues with the price."

"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 price of the solution is expensive."

"The tool is a premium product, so it is very expensive."

"That is one of the great features. I was able to access the majority of the features and services for free."

More Cloudflare pricing and cost advice

The robust global connectivity cloud platform that is Cloudflare ensures users are able to connect to the Internet quickly, securely, and reliably. Cloudflare is one of the world's largest networks in the marketplace today. Using Cloudflare, businesses, educational entities, NGOs, vloggers, bloggers, and anyone else with an internet presence can experience more secure, faster websites and applications.

Cloudflare has safe, secure data centers in close to 300 cities worldwide to ensure every
client request is filled as quickly as possible. It is Cloudflare’s edge network that makes this
possible by keeping content and other services as close to each client as possible, so the

Reviews from real users

“Many websites require an SSL certificate because they sell stuff and want SSL. Cloudflare
comes with an SSL certificate built in. It's automatic. You sign yourself up for Cloudflare, and
an SSL certificate automatically protects your website. If you have a connection between your
website and your host, the server, Cloudflare, and the host, you don't necessarily need a
certificate.” Spencer M., Owner at Tech Exchange

“What I like best about Cloudflare is that my company can use it to trace and manage
applications and monitor traffic. The solution tells you if there's a spike in traffic. Cloudflare
also sends you a link to check your equipment and deployment and track it through peering,
so it's a valuable tool.” Daniel P., Network Engineer at Ufinet

“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.” PeerSpot user, Competence Center Manager at a tech services company
