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 solution offers the flexibility to control configuration rules."

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

"Generally, I am satisfied with this product."

"When using services like Heroku, Cloudflare is very useful for CNAME flattening. I also use it for their end-to-end SSL with TLS authentication on nginx for securing servers."

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

"Easier http to https redirect using page rules"

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

More Cloudflare pros

"The GUI is very use-friendly. You can configure it through CLI or GUI, they give you an option to choose. It's a good solution in terms of the appliance itself. It's very light compared to other brands that offer DDoS solutions."

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

"The solution's support is one of the coolest things about the product. I"

"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 has reduced the amount of manual intervention required during an attack. We have the inline solution and when it comes to the customers that we have on it, it has saved us some troubleshooting time."

"It is a scalable solution."

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

"I had a rather positive experience with A10 Networks Support Service."

More A10 Thunder TPS pros

"The equipment works very well, and I have not encountered any issues with it. It is a good solution for my company."

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

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

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

"The solution is very user-friendly and very easy to use."

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

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

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

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."

"Technical support is not well developed. While there are good engineers, Cloudflare does not offer hands-on technical support to fix customer problems but rather a self-service model."

"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."

"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 pricing could be improved."

"Support response time could be improved."

"Sometimes their more advanced caching tools can cause higher first-byte times and problems with JavaScript."

"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."

More Cloudflare cons

"We have had some issues with implementation. So, it is the only area that needs improvement."

"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."

"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."

"If there's one aspect of A10 that needs improvement it would be the training. All of their training is done online, at least in what we've been exposed to. I would like to have a classroom environment for training... It would give [people] a chance to provision it."

"Its documentation could be better."

"The solution needs improvement in terms of fail-open."

"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."

"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."

More A10 Thunder TPS cons

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

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

"Alerts and reporting features must be improved."

"The product’s pricing needs improvement."

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

"The challenge lies within the customer environment, particularly in Brazil, where companies have stringent security requirements for implementing solutions."

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

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

More Fortinet FortiDDoS cons

Pricing and Cost Advice

"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."

"I give the price a five out of ten."

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

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

"When you compare Cloudflare DNS to other solutions, such as Akamai, the price is reasonable."

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

"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."

More Cloudflare pricing and cost advice

"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."

"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."

"Pricing is very reasonable."

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

"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."

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

"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
