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.

Good security and protection but needs better pricing
We'd like more AI to be used. Right now, they don't use it enough. We'd like the solution to offer open sessions so that the session syncs to other IP faster. The protection could be a bit better in various areas. The stability could be a bit better. It could offer better pricing.

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 DNS is security."
"Centralized, full-featured DNS."
"New and innovative way to protect the client's data."
"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 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."
"It is easier to configure and develop documentation to see how we have configured firewalls."
"Its ease of integration with Office 365 and the fact that it's a good product compared to what I had before"
"I like Cloudflare's application gateway and DDoS protection."
"We have found the most valuable features to be the web application, minimal skills required for management, control through policies, and automation."
"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 integration it has with GitHub is great."
"The most valuable feature of Azure Web Application Firewall is its ability to filter requests and block false positives by using custom rules and the OWASP rule set."
"Azure WAF is extremely stable."
"It's quite a stable product and works well with Microsoft products."
"It has been a stable product in my experience."
"The most valuable feature is that it allows us to publish our applications behind the firewall."
"F5 technical support is really good."
"The most valuable feature of F5 Silverline Managed Services is the benchmark performance."
"The most valuable feature of F5 Silverline Managed Services is it becomes similar to a distributed architecture."
"Its flexibility is the most valuable because it is a managed service. The good part is that you don't need to set it up. It just needs DNS routing, which is the easiest thing. Our client had Akamai for certain websites because they were using CDN features. They had NetScaler on the internal zone, F5 AWAFs on the data centers, and no WAF at all in the cloud. One of the main activities of the project was to move all these policies into a single WAF so that we could control and use that as a choke point. That exercise itself was very easy because it was a managed service and F5 Silverline Web Application Firewall does that for you. That's the best thing about F5 Silverline Web Application Firewall. It is easy to apply policies on-premises. If you have AWAF on-premises and you want to replicate some policies on F5 Silverline Web Application Firewall, other than the policies that it applies by itself, it is easy because you have a team that supports it. F5 Silverline Web Application Firewall works perfectly fine. It pretty much does everything that an Advanced WAF on-premises should do."
"It's a good front end for public infrastructure"
"The most important feature is that they have seven firewall protection, to protect our web servers."
"The most valuable feature of F5 Silverline Managed Services is its cloud-native functionality and the high level of protection it provides."
"Most vendors fulfill the requirements for standard DDoS protection, but F5 Silverline Managed Services has a better understanding of defending web applications like HTTP and can mitigate more bot activity than any other vendor."
 

Cons

"The tool needs to improve caching of servers. The product needs to include PFX certificate as well."
"Even if I wanted to, I wouldn't be able to buy Cloudflare in my country."
"Support response time could be improved."
"Cloudflare should add more documentation and pricing to the cloud version."
"I believe they currently have this feature, but there will most likely be integration with APIs so we can control some features through API."
"The solution could work at being less expensive. It costs a lot to use it."
"The solution could be more user-friendly."
"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."
"The management can be improved."
"We would like to see additional site services using AI to provide information about blocking requests and offer analytics on the origin of calls."
"From a reporting perspective, they could do more there."
"Azure WAF should not be deployed in the middle of the traffic."
"There is a need to be able to configure the solution more."
"I would say that Azure's customer service is not that good...I am not very happy with the support offered."
"Deployment should be simplified so that a non-techie can handle it."
"In Brazil, we have some problems with the phone service that affect our connection with the cloud. However, it isn't common."
"The price of F5 Silverline Managed Services could be better."
"F5 Silverline Managed Services can improve by reducing the price."
"F5 Silverline Managed Services can improve by adding features that Palo Alto has."
"F5 Silverline Web Application Firewall, being a new product in the market or comparatively related to a new product, currently supports less number of PoPs. They should introduce more PoPs. The current number of PoPs that they have is around 10 or 12, which is still relatively less as compared to 2,400 plus PoPs that Akamai offers. The user latency or the number of hops a user needs before reaching the actual web application is less in Akamai because it has its internal fabric to route the traffic. They need to spin up more data to increase its traffic handling capability. They can also include the bot detection capability, though it is a pretty advanced functionality. If they could include DataDome like functionality, that is, bot prediction, then F5 Silverline Web Application Firewall will be top-notch in the market."
"The navigation is difficult to use."
"I just hope the price can be cheaper."
"We'd like more AI to be used. Right now, they don't use it enough."
"There is room for improvement in the stability of the solution."
 

Pricing and Cost Advice

"We don't have any issues with the price."
"The cost primarily depends on the size of the organization."
"The pricing for the service is reasonable, neither excessively cheap nor prohibitively expensive. It aligns well with the value of their solution."
"The product's pricing is cheap."
"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."
"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 price is reasonable. It is approximately $2,000 US per month."
"We have an enterprise agreement with Microsoft and the pricing is good."
"I give the pricing a nine out of ten."
"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."
"The price is for this solution is fair and there is a license needed."
"F5 Silverline Web Application Firewall works based on your bandwidth. They look at the clean bandwidth and do the pricing. 20% of a total pipe would be a clean bandwidth. The list price or a non-negotiated price for F5 Silverline Web Application Firewall would be around $2,200 per application per year for everything that you need. When you get into an enterprise kind of a setup, they negotiate this to the last bit. I would easily take 20% on that, which would be the cost, but it should cover all your Advance WAF features, bot protection, tech campaign, etc. It is built as a package and gives you most of the capability. You don't get the mobile SDK, which is an additional license. Mobile SDK is required only if you're buying or if you have a mobile application, and you are going to instrument F5 or Imperva into your mobile appliance. This anyways would be an additional module. It doesn't come within the WAF, but it is a WAF feature."
"The product’s pricing is reasonable."
"The price of F5 Silverline Managed Services could be reduced."
"The price of F5 Silverline Managed Services could be better, they are not very flexible. The price of the solution is based on the requirements of the enterprise."
