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.

Comprehensive suite simplifies configuration while frequent updates require management

Mainly, it comes with the complete suite of Microsoft services. I can use it in conjunction with the best options and other features that come with it. Configuration is much easier than using different platforms. For example, if I have hosted the application in AWS and am using the Application Firewall from Azure, there are certain additional steps to follow when configuring them. With Microsoft, everything is within a single suite, making it easier to configure and plan. Azure continually upgrades platforms and sends us messages to upgrade to the next version, simplifying the process. Later, it's much easier if I want to upgrade the software platform, scale it, or move it to a different application host as the whole suite comes together. The return on investment is good. If I am doing applications for clients, I can invoice them for better costs. Most applications that I run and use have a better return on investment.

Mitigates more bot activity when defending web applications than any other vendor but comes at a price

F5 Silverline Managed Services is expensive. You do get world-class quality of mitigation, but I think it is still pricey. You can find similar services, potentially of slightly lower quality, from other vendors like Cloudflare or Akamai for about half the price. When you compare what you get for the money you spend at Cloudflare or Akamai, you do get less protection but you are not dishing out too much for it. On the other hand, at F5 Silverline Managed Services, you do get better protection but, but you are paying double for it. We have had mixed feedback from our clients about this. Most of them would rather pay less for a bit of a lower-quality defense than overshoot their budget. The most common piece of feedback we receive is that the difference in protection levels is not reflected in the price.

Quotes from Members

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

Pros

"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 attacker won't have details since my public IP is anonymous. It offers us good privacy."

"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."

"It is a fast and secure DNS."

"The most valuable feature is its usability."

"Generally, I am satisfied with this product."

"It's very user-friendly."

"Its ease of integration with Office 365 and the fact that it's a good product compared to what I had before"

More Cloudflare pros

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

"It is almost impossible to access these assets from outside, requiring a very skilled attacker to obtain asset tokens of a customer using Azure."

"The solution has good dashboards."

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

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

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

"Azure WAF is extremely stable."

"Configuration is much easier than using different platforms."

More Azure Web Application Firewall pros

"The initial setup is very straightforward."

"The product’s UI is easy to understand."

"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 valuable features are the configuration and configuring the process."

"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."

"The stability of the solution is very good."

"F5 Silverline offers load balancing, flexibility, and reliability."

More F5 Silverline Managed Services pros

Cons

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

"The timing aspect can lead to it being considered overpriced. This is a particular concern we have with Cloudflare, as they may struggle with accurately detecting the client."

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

"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."

"I would like Cloudflare to offer a dedicated account manager for large enterprise clients like us."

"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."

"One area of improvement is in the Access Rules. Hypothetically, if we wanted to block or challenge traffic outside of the United States, the only way to currently do that (as far as I know) is to enter every single country outside of the United States. That could be a labor intensive job. A solution could be to enable users to create a rule where traffic is only allowed within a certain country."

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

More Cloudflare cons

"Upgrading the platform regularly is necessary for security, however, frequent updates every six months or year from Azure can be a maintenance overhead."

"We would like to see additional site services using AI to provide information about blocking requests and offer analytics on the origin of calls."

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

"Azure WAF should not be deployed in the middle of the traffic."

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

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

"There is a need to be able to configure the solution more."

"The management can be improved."

More Azure Web Application Firewall cons

"Sometimes tech support can be slow. They take more time assigning engineers to complex issues, however, they resolve the issues by joining me to fix them."

"The product could be improved on the global load and the integration with the other solution like Cisco and Dell. As a representor of the operation, we prefer to have one platform which can accommodate all type of integration. We are also looking for more improvements in the security policy configuration."

"I just hope the price can be cheaper."

"The navigation is difficult to use."

"In terms of the scalability, this part is always so confusing because they are checking for packet count. Also, after an attack, they said that the throughput must be from gigabits but then I check my bandwidth and it is already done in gigabits. So it is a little bit confusing."

"There is room for improvement in the stability of the solution."

"The price of F5 Silverline Managed Services could be better."

"There is a lot of room for improvement with their tech support. I am not sure F5 Silverline Managed Services can be classified as having tech support."

More F5 Silverline Managed Services cons

Pricing and Cost Advice

"We are using the free version."

"A free version of the solution is available."

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

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

"The product's pricing is minimal compared to other products."

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

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

"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."

More Cloudflare pricing and cost advice

"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."

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

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

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

"The product’s pricing is reasonable."

"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."

"The price of F5 Silverline Managed Services could be reduced."

"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."

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
