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

"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."
"The technical support is good."
"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."
"Centralized, full-featured DNS."
"Cloudflare allows us to self-host services such as Rocket.Chat and Node-RED, in high-availability mode, thanks to round robin DNS which allows us to share one hostname between our two locations."
"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."
"The web application firewall brought us good security and a view of the accesses/blocks of the entire domain and subdomain that were accessed both by region (country) and IPs."
"The stability of the solution is very good."
"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."
"It's a good front end for public infrastructure"
"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."
"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."
"F5 technical support is really good."
"The most valuable feature is flexibility."
"The most valuable feature is the controller that determines when and how traffic can be moved to the cloud."
"The reporting is very good and provides us with a comprehensive description of where attacks are emanating from."
"DDoS Protection Service provides excellent defense in the cloud, and the implementation and migration are very straightforward."
"Recently, our company has been facing difficulties due to attacks originating from the Russian Federation. DefenseFlow has proven to be a highly effective solution in protecting our customers."
"Radware DefensePro is one of the best solutions for on-premise protection."
"It offers valuable insights into ongoing and past attacks, aiding in post-incident analysis and continuous improvement of our cybersecurity strategy."
"The best feature is the auto mitigation of the DefensePro solution created by Radware."
"The product integrates well with Cisco."
 

Cons

"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 would like Cloudflare to offer a dedicated account manager for large enterprise clients like us."
"The tool needs to improve caching of servers. The product needs to include PFX certificate as well."
"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."
"Technical support is lacking."
"The reporting can definitely be improved to offer a lot more explanation on something that may have happened or has actually happened."
"There might be helpful if there was some web application firewall feature."
"In the last two years, there has been a certain amount of downtime when using the VDM."
"We need to have support for cloud protection, which is not offered by this solution."
"F5 Silverline Managed Services can improve by reducing the price."
"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."
"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."
"Improvements could include the creation of highly optimized profiles, optimization deployments, and compression profiles for better performance."
"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."
"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 dashboard could be updated."
"I would like to have more granular steps according to protected bandwidth, so the granularity should be better."
"I would like to see more focus on layer seven protection."
"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."
"I would like to see more graphics within the dashboard. Right now, you are required to buy tools in order to have graphical representation for your monitoring."
"Radware should focus on customization and integration, allowing routers and firewalls from other parties to integrate with the DDoS solution, enhancing security."
"It would be ideal if they could expand protocol support to cover emerging communication standards and ensure comprehensive protection against diverse attack vectors."
"The rise of generative AI and machine learning in cyberattacks demands more advanced defense strategies."
 

Pricing and Cost Advice

"The pricing depends on the usage, but the cheapest would be around 5,000 USD a month."
"The product's pricing is minimal compared to other products."
"There are no additional costs beyond the standard licensing fees."
"Cloudflare's pricing is not much higher and is good for middle-level organizations."
"The product's pricing is cheap."
"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."
"We don't have any issues with the price."
"The pricing for the service is reasonable, neither excessively cheap nor prohibitively expensive. It aligns well with the value of their solution."
"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 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 cost for maintenance is cheaper because the majority of the deployments using the solution are in areas where cost of maintenance is also lower."
"The product's pricing is a good value."
"Radware Cloud DDoS is very expensive."
"The price was well over six figures."
"Licensing of Radware is quite simple and straightforward, while Arbor DDos is a bit complicated."
"The price varies by use case and there are monthly and annual licensing options. If you deploy on-premise, there is an annual license with the amount dependent on the throughput you need and which features you will be using - i.e. IPS, behavioral, etc."
"Radware DefensePro is expensive when considering the issue we have and its limitations."
"The pricing is based on the amount of network traffic and the number of packets being inspected."

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).
