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

"The technical support is good."
"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."
"It is easier to configure and develop documentation to see how we have configured firewalls."
"We're using dynamic components to build flexible pages to create and manage Git merge requests for code and reviews."
"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."
"Cloudflare offers CDN and DDoS protection. We have the front end, API, and database in how you structure applications."
"It is a fast and secure DNS."
"The solution is very good at mitigating threats."
"It's great for protecting against DDoS attacks."
"The solution has good dashboards."
"The integration it has with GitHub is great."
"Configuration is much easier than using different platforms."
"We have found the most valuable features to be the web application, minimal skills required for management, control through policies, and automation."
"It's quite a stable product and works well with Microsoft products."
"It is almost impossible to access these assets from outside, requiring a very skilled attacker to obtain asset tokens of a customer using Azure."
"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."
"F5 Silverline offers load balancing, flexibility, and reliability."
"The most valuable feature of F5 Silverline Managed Services is the benchmark performance."
"The most valuable feature is flexibility."
"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."
"The most valuable features are the configuration and configuring the process."
"The product’s UI is easy to understand."
"The most important feature is that they have seven firewall protection, to protect our web servers."
"F5 technical support is really good."
 

Cons

"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."
"For large enterprises, the pricing is okay. However, the enterprise price for small projects is a bit high. A mid-tier pricing option would be beneficial."
"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."
"Support response time could be improved."
"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."
"The documentation could improve for Cloudflare DNS."
"The product support needs to be accessible from more places, a wider area of coverage."
"Technical support is lacking."
"From a reporting perspective, they could do more there."
"The support for proxy forwarding could improve."
"Some Azure applications, like the web application firewall, require a certain level of SKU for hosting setup. The basic setup does not allow me to use the web application firewall and other additional services."
"Upgrading the platform regularly is necessary for security, however, frequent updates every six months or year from Azure can be a maintenance overhead."
"There is a need to be able to configure the solution more."
"Deployment should be simplified so that a non-techie can handle it."
"The management can be improved."
"In Brazil, we have some problems with the phone service that affect our connection with the cloud. However, it isn't common."
"The navigation is difficult to use."
"F5 Silverline Managed Services can improve by reducing the price."
"I just hope the price can be cheaper."
"The price is high in comparison to other products."
"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."
"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."
"The price of F5 Silverline Managed Services could be better."
"We'd like more AI to be used. Right now, they don't use it enough."
 

Pricing and Cost Advice

"Cloudflare's pricing is not much higher and is good for middle-level organizations."
"The price is reasonable."
"So far I use free tier and happy with it. You can subscribe to business package if needed."
"The tool is a premium product, so it is very expensive."
"The pricing for the service is reasonable, neither excessively cheap nor prohibitively expensive. It aligns well with the value of their solution."
"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 think the pricing is competitive. I think as far as licensing is concerned it's pretty straightforward because it's based on domain. It's just that sometimes domains could be tricky with some customers."
"That is one of the great features. I was able to access the majority of the features and services for free."
"I give the pricing a nine out of ten."
"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."
"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 for this solution is fair and there is a license needed."
"The price is reasonable. It is approximately $2,000 US per month."
"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."
"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."
