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.

Successfully protects from DDoS attacks
The product is good, but the company could improve its services by appointing customer success managers. This would ensure better interaction with customers and help resolve issues on both customer and supplier ends. Most other security product companies such as Palo Alto and Forcepoint appoint customer success managers to interact with customers and ensure that the product they have purchased is used perfectly. If we are facing any kind of issues in using the product or service, the customer success manager should get things right.

Quotes from Members

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

Pros

"Even when there is a high load on our servers, Cloudflare is able to cache the data and serve it to users, ensuring they can still access the website."
"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 features of Cloudflare were found to be more beneficial and led to the decision to utilize it over other options."
"It is a fast and secure DNS."
"Its ease of integration with Office 365 and the fact that it's a good product compared to what I had before"
"The attacker won't have details since my public IP is anonymous. It offers us good privacy."
"The most valuable feature of Cloudflare DNS is its global reach and it is always evolving."
"The solution is stable, and the DNS servers are simple to use."
"It's a good front end for public infrastructure"
"The product’s UI is easy to understand."
"The initial setup is very straightforward."
"The most important feature is that they have seven firewall protection, to protect our web servers."
"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 feature of F5 Silverline Managed Services is the benchmark performance."
"The most valuable features are the configuration and configuring the process."
"The initial setup is straightforward."
"They have a hybrid model approach if a client wants to go that way."
"The product integrates well with Cisco."
"All of our traffic has to pass through the appliance, so we can very quickly mitigate the attack. This is a very valuable feature. On top of that, it's not only volumetric attack protection that the solution offers, but also layer 7 attack protection as well."
"It has not gone down for a quite long time. It's working fine."
"The most important part is that Radware DDoS integrates seamlessly and provides anomaly identification, real-time notifications, and security against DDoS attacks. It also helps us with multi-layer volumetric attacks. It shields us from global botnet threats."
"DDoS Protection Service provides excellent defense in the cloud, and the implementation and migration are very straightforward."
"The most valuable feature is the ability to create signatures on-demand."
"Its functionality is very good."
 

Cons

"Cloudflare could offer a better view or maybe dashboards of the main resources used in the client."
"Integration involving API with other products could be more user-friendly."
"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."
"The product needs to improve its automation."
"Cloudflare should add more documentation and pricing to the cloud version."
"Areas like how assessment, discovery, and payload are dealt with and how it all comes into your organization can be considered when trying to make suggestions to Cloudflare for improvements."
"The documentation could improve for Cloudflare DNS."
"I just hope the price can be cheaper."
"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."
"We'd like more AI to be used. Right now, they don't use it enough."
"The price is high in comparison to other products."
"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."
"Right now, we have DefensePro 6. The only complaint I have is that SSL inspection, when activated, consumes a lot of resources on the machine. We are currently reviewing a possible change to DefensePro X, the new version, which has a separate module with its processors."
"The solution needs a bit more functionality. It would be good if DefensePro could have anti-bot functionalities in order to stop bots like web scrapers from getting onto our customers’ network."
"This product would be improved if ongoing live monitoring with dashboards were added."
"It could incorporate more intelligence for reacting with web site visitors."
"I would like to see more focus on layer seven protection."
"The solution is a little more pricey than other options on the market."
"If they would go to a cloud-based approach, that would give much more flexibility in terms of working with them."
"Radware DefensePro requires a continuous learning process. Using this technology, we can improve our network. Based on the different attack mechanisms, we use Radware DefensePro to provide security for our clients' networks very effectively."
 

Pricing and Cost Advice

"We are using the free tier of the solution."
"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."
"We don't have any issues with the price."
"The product's pricing is cheap."
"So far I use free tier and happy with it. You can subscribe to business package if needed."
"The price is reasonable."
"A free version of the solution is available."
"The price of the solution is expensive."
"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 price of F5 Silverline Managed Services could be reduced."
"The product’s pricing is reasonable."
"Radware's switch to a pay-as-you-go model last year provides great flexibility."
"The pricing is based on the amount of network traffic and the number of packets being inspected."
"Radware's Cloud DDoS Protection Service stands out for its competitive pricing, making it a strong contender in our decision."
"The initial cost is over $100,000 for one appliance."
"The Radware DefensePro was bundled together with our security platform."
"The price was well over six figures."
"Radware DefensePro is expensive when considering the issue we have and its limitations."
"The product's pricing is a good value."

I highly recommend Cloudflare. We switched from Akamai Prolexic to Cloudflare and couldn't be happier. We also got the worlds fastest DNS and speeded up our site load times with the 200+ edge locations near to our customers.

You can have a look to Imperva Cloud WAF, the anti-DDoS mitigation is under 1s and works very well. I observed a lot of DDoS attacks that were well managed (even not seen by the customer) by Imperva, I can recommend it (try it with a trial, you'll be able to have your own opinion).
