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.

A highly stable solution that can be used for load balancing

We contacted the solution's technical support to maintain and exchange the power supply. A few versions ago, we had some CPU and memory problems. We just started the appliance, and it was already on 70% of CPU usage. We first contacted our reseller in Brazil and then escalated the issue to A10 Thunder TPS support. The reseller in Brazil was a little slow, but the A10 Thunder TPS support was fast.

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."

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

"The features of Cloudflare were found to be more beneficial and led to the decision to utilize it over other options."

"The most valuable feature is its usability."

"The simplicity of the overall dashboard makes it a great product for a user like me who has less understanding of the internet than a developer or other more technical people. It gives me peace of mind. I also love the easy customization of the Page Rules."

"Cloudflare has many features."

"Smaller businesses have seen great ROI due to the low investment and strong performance."

"Cloudflare offers CDN and DDoS protection. We have the front end, API, and database in how you structure applications."

More Cloudflare pros

"The most valuable feature of A10 Thunder TPS is load balancing."

"The response time to an attack is instant. We've used some outsourced solutions in the past, out in the cloud, that weren't so quick. But it's all within our control now. We control how fast it mitigates."

"Thunder TPS has automated mitigation and fully managed support in case the device cannot handle the attack. They have engineers available to respond."

"The solution is easy to use and implement in terms of operations."

"They give us the ability to configure many features for DDoS. There are many items that we can use."

"We selected the solution because of its programmable automated defense using RESTful API. We didn't want to connect to the box. We wanted to be able to do some automation. We wanted to have our own portal because we wanted to connect our customers to our own UI using the A10 API. It has been good and exactly what we need."

"We can keep track of all the customer's requirements. We can forecast our trails and we can forecast our overall financial things."

"The primary benefit that we see from their systems is that their filtering technology has the ability to detect and drop the malicious traffic from the legitimate traffic with a high success rate. That, in combination with the very small effort needed to manage their systems, are the two most important benefits to us."

More A10 Thunder TPS pros

"The equipment works very well, and I have not encountered any issues with it."

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

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

"I find the interface easy to use."

"This solution can protect Layer 3, Layer 4 and Layer 7 attacks of applications for us."

"The solution already has security profiles and it can protect from DDoS attacks and other kinds of attacks."

"The product's initial setup phase was really easy."

"Among its key features: Detects and mitigates DDoS attacks at L3 to L7; negligible to zero false-positives; Generates and sends reports without the need for an expensive third-party solution."

More Fortinet FortiDDoS pros

Cons

"The product needs to improve its automation."

"There could be more courses with engineers. I like e-learning, however, having a specialist in a classroom is more comfortable for me."

"For the free and Pro plans, Cloudflare could use a simple bot to provide information to users. This would improve support, especially for less advanced users who utilize the free components."

"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."

"Areas like how assessment, discovery, and payload are dealt with and how it all comes into your organization can be considered when trying to make suggestions to Cloudflare for improvements."

"The integration of LLMs on the dashboard is something that is needed in the tool."

"There should be a specific price list for enterprise-level customers."

"DNS Management."

More Cloudflare cons

"I had issues with the user interface because, when putting settings up, the system asked me for strange things like virtual local networks that I didn't create."

"They have a cloud scrubbing feature that redirects the traffic if the on-prem appliance can't accommodate a large amount of traffic but it's not available where we are."

"The upgrade process for the boxes is not efficient. We have to go through the A10 aGalaxy where we have issues, like timeouts. They told me it was fixed in the latest version, but I tried to do it on the Portal and it is not working all the time."

"We currently do not use the solution's machine-learning-powered Zero-day Automated Protection because of an issue with it... We also use the aGalaxy platform, which is a management platform for the TPS devices. The issue is that some TPS features were added at the TPS level but weren't carried over to aGalaxy, and we manage all of our devices through aGalaxy. So we can't actually use some of the new features that are available on the TPS because that functionality doesn't exist in aGalaxy. That is one of my biggest complaints."

"I would like for them to develop an advanced reporting feature."

"I rate Thunder TPS seven out of 10 for scalability."

"The problem here is when you buy another box from A10, they want to put Thunder TPS to run, and it works okay, after which we cannot block it for another solution to be used, which is a problem for me where improvements are needed."

"It is very difficult to implement. It should be made a bit easier to implement. There is also a lack of resources on the internet. They need to develop more resources."

More A10 Thunder TPS cons

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

"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 solution can be a little more user-friendly and it can be more affordable."

"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 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."

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

More Fortinet FortiDDoS cons

Pricing and Cost Advice

"So far I use free tier and happy with it. You can subscribe to business package if needed."

"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 solution is expensive when compared to other products but offers unlimited bandwidth."

"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."

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

"The product's pricing is cheap."

"The price of the solution is expensive."

"The cost primarily depends on the size of the organization."

More Cloudflare pricing and cost advice

"The financials are always a challenge with this type of technology. That's not really a product-functionality thing but it's the area where we push A10 the most."

"We may need to pay fifty percent more if we purchase other solutions. For the payments made to A10 Thunder TPS, we have received three-year support."

"We had a customer who was down for six hours and the loss of revenue for him was three times the price he was paying for us per year. The customer just said, "I don't care about paying you because on only one attack I saved money. It's three times better than losing money.""

"Pricing was much higher with Arbor (APS) for the same type of solution."

"Pricing is very reasonable."

"The tool is expensive. If one is low price and ten is expensive, I rate the tool's price as a ten."

"We did a price survey, and compared to other solutions, A10 Thunder TPS wasn't cheap."

"The solution is reasonably priced."

"It's quite pricey."

"The product’s pricing needs improvement."

Overview

Cloudflare is a highly-regarded Content Delivery Network (CDN) and a Distributed Denial-of-Service (DDoS) protection solution. 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.

Currently, there are millions of Internet locations on Cloudflare, and the Cloudflare network
continues to grow every day by the thousands. The solution is able to fulfill the requests for
millions of websites seamlessly and serves on average 45 million HTTP requests per second.

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
information requests are always only seconds away.

Many organizations that work in democracy, civil society, human rights, or the arts are able to
access Cloudflare's highest levels of protection for free via Project Galileo. Additionally, official
election websites can be secured from hacking and fraud through Cloudflare’s Project
Athenian, also at no additional cost.

Cloudflare can also help organizations of all sizes develop a robust zero-trust strategy to
ensure the highest levels of productivity and profitability. Employees, stakeholders, and end users have a greater level of satisfaction and overall improved user experience, which can, in
turn, result in higher revenues and overall ROI. Zero-trust and BYOD (bring your own device)
access ensure end users and employees always have the best resources and technology
available to them at all times.

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
