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.

Is priced well, is stable, and the initial setup is straightforward

I previously used Barracuda Web Application Firewall. I hope that Azure Web Application Firewall will look at other products and replicate some of their functionality. Azure WAF is doing great because it is designed to host web applications in Azure. However, it can be improved with other services. Barracuda is the most advanced firewall in the industry, so Azure WAF could pick some of its features and replicate them into its own application firewall. Barracuda WAF was deployed in parallel to the traffic. Azure WAF should not be deployed in the middle of the traffic. It should support both public and private points of presence. Additionally, like Barracuda, Azure WAF should have an inspection engine that covers not just Microsoft products, but also products from other manufacturers. This would be a great addition to the product and would increase its security functionality.

A good solution to implement web application firewall for applications

There are some lags in Signal Sciences for the web application firewalls. Even if we create some custom rules, Signal Sciences cannot capture some of the malicious traffic. There is a little bit of complexity with custom rules that should be removed. Signal Sciences should add a feature called rate limiting with multiple options, wherein I can create a rate limiting based on the cookie request or the IP.

Quotes from Members

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

Pros

"It's very user-friendly."

"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 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 features of the solution are performance and security."

"The most valuable feature of Cloudflare is that it has a free version. They give us the free version with the anti-DDoS features and also the load balancing solution."

"The UI is good."

"The solution provides good load balancing and protection against DDoS attacks."

"From what I've seen so far, there are no negatives to report as of yet"

More Cloudflare pros

"It has been a stable product in my experience."

"Azure WAF is extremely stable."

"The initial setup is easy and straightforward...Azure Web Application Firewall is a scalable product."

"It's great for protecting against DDoS attacks."

"It's quite a stable product and works well with Microsoft products."

"It's a good option if you want a solution that's ready to go and easy for your team to learn. It's cloud-based, so you don't need to buy or maintain any hardware infrastructure."

"The solution has good dashboards."

"The most valuable feature is that it allows us to publish our applications behind the firewall."

More Azure Web Application Firewall pros

"When configuring a web application firewall using Signal Sciences, we configure a rule whereby no one except a few people can access the application."

"Fastly (Signal Sciences) integrates and tags the intermittent traffic based on patterns. It generates signals and provides them in a dashboard where we can view them and decide whether to allow or deny traffic. It's a more advanced and easy-to-navigate dashboard."

"The product's most valuable feature is its ability to set up the rules easily."

Cons

"The tool needs to improve caching of servers. The product needs to include PFX certificate as well."

"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."

"The solution could work at being less expensive. It costs a lot to use it."

"I believe they currently have this feature, but there will most likely be integration with APIs so we can control some features through API."

"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."

"The reporting can definitely be improved to offer a lot more explanation on something that may have happened or has actually happened."

"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."

"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."

More Cloudflare cons

"The management can be improved."

"I would say that Azure's customer service is not that good...I am not very happy with the support offered."

"The knowledge base could be improved."

"From a reporting perspective, they could do more there."

"The support for proxy forwarding could improve."

"Deployment should be simplified so that a non-techie can handle it."

"The documentation needs to be improved."

"In Brazil, we have some problems with the phone service that affect our connection with the cloud. However, it isn't common."

More Azure Web Application Firewall cons

"The areas that could be improved in Signal Sciences include the effectiveness of rules, as many didn't function optimally and required custom rule-writing to address bypasses for WAF."

"Even if we create some custom rules, Signal Sciences cannot capture some of the malicious traffic."

"Fastly don't support caching for China users. That's the only feature lacking compared to Akamai."

Pricing and Cost Advice

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

"The product's pricing is cheap."

"I believe their performance has improved, but I'd like to refrain from discussing the pricing aspect related to the cloud. The pricing, in my opinion, could be simplified, and I think they should consider reevaluating the pricing for support, as it can be quite high. At times, this cost can make it challenging to choose CARFAGuard or opt for the support."

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

"The price of the solution is expensive."

"We are using the free tier of the solution."

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

"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

"I give the pricing a nine out of ten."

"The price is reasonable. It is approximately $2,000 US per month."

"We have an enterprise agreement with Microsoft and the pricing is good."

"The price is for this solution is fair and there is a license needed."

"Azure WAF has price advantages over other WAF solutions. The pricing model is flexible because you pay on a scale based on the level of protection you need."

"The price of the solution depends on your architecture and how you manage it. You can control the cost in Azure quite well. The costs do not directly correlate to expenses in the features we are using."

"Signal Sciences is pretty cheap compared to other solutions."

"The pricing is 50% less than Akamai."

"The product has an affordable cost."

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
