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.

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.
ÖS
Eliminated DDOS attacks, provides excellent mitigation service
I rate it eight out of 10. It would get a nine if the web portal was better and 10 if the price was lower. We have been using it for three years. We canceled the contract recently and are looking into using another vendor to reduce the price by two-thirds.

Quotes from Members

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

Pros

"New and innovative way to protect the client's data."
"The DDoS protection is the most valuable aspect of the solution."
"It is a fast and secure DNS."
"The most valuable features of the solution are performance and security."
"It is easier to configure and develop documentation to see how we have configured firewalls."
"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."
"Easier http to https redirect using page rules"
"Cloudflare consolidates various capabilities into one product, streamlining processes."
"The product’s UI is easy to understand."
"The most valuable features are the configuration and configuring the process."
"The best advantage of F5 Silverline Managed Services is that it is easy to use."
"We have a lot of businesses that we put behind this solution, and it has really helped us in terms of monitoring the logs and incidents."
"The most valuable feature of F5 Silverline Managed Services is the benchmark performance."
"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 initial setup is very straightforward."
"The most valuable feature of F5 Silverline Managed Services is it becomes similar to a distributed architecture."
"The solution does not have hardware or maintenance requirements and is very easy to scale."
 

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."
"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."
"Cloudflare's console should be made more user-friendly."
"If they improve on the placement of their data centers, it would be better. I'm living in a remote area. I would like to connect to them without any kind of lag."
"Cloudflare could be improved by introducing a mid-tier pricing option."
"It should be easier to collect the logs with companies like Sumo. However, based on my discussions with the salespeople, I understand that's how they make their money. With the enterprise product, they want people doing those kinds of enterprise features to do the logging. They want them to pay a lot of money, and that's where I have an issue with them. That should be a default. You should be able to get the log no matter what. The logging should be universal."
"Cloudflare should add more documentation and pricing to the cloud version."
"You need to have Linux knowledge in order to use the shell."
"The navigation is difficult to use."
"I just hope the price can be cheaper."
"F5 Silverline Managed Services can improve by reducing the price."
"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."
"F5 Silverline Managed Services can improve by adding features that Palo Alto has."
"We need to have support for cloud protection, which is not offered by this solution."
"The price is high in comparison to other products."
"The solution needs additional product options for small and medium enterprises."
 

Pricing and Cost Advice

"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 pricing for the service is reasonable, neither excessively cheap nor prohibitively expensive. It aligns well with the value of their solution."
"When you compare Cloudflare DNS to other solutions, such as Akamai, the price is reasonable."
"The price of the solution is expensive."
"The cost primarily depends on the size of the organization."
"We don't have any issues with the price."
"There are no additional costs beyond the standard licensing fees."
"We are using the free version."
"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."
"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 product’s pricing is reasonable."
"The pricing is a pay-as-you-go model that is charged by the hour."
