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."
"Easier http to https redirect using page rules"
"It is a stable solution. I rate the stability a ten out of ten...I rate the scalability a ten out of ten."
"From what I've seen so far, there are no negatives to report as of yet"
"It's very user-friendly."
"The solution is stable, and the DNS servers are simple to use."
"There are key things that are used for our enterprise customers, such as Lambda and DNS."
"The most valuable feature of F5 Silverline Managed Services is its cloud-native functionality and the high level of protection it provides."
"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."
"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 most valuable feature is flexibility."
"The initial setup is straightforward."
"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."
"Radware Cloud DDoS Protection Service goes beyond the essential Layer Three and Layer Four protection, which are practically mandatory these days."
"Radware's support is first class."
"The intuitive user interface makes the entire process seamless and efficient."
"The product is very effective and performs well on devices."
"As a service provider, we use the SecOps dashboard feature. That's where we check the time of attacks to see if an attack is happening at the moment or if it has already happened... It is very dynamic and helps us know when an attack occurred, how long it lasted, and what type of attack it was."
"The pricing is reasonable. It's not overly expensive."
"The best feature is the auto mitigation of the DefensePro solution created by Radware."
"Radware DefensePro is one of the best solutions for on-premise protection."
 

Cons

"They lack a good way to manage DNS as a company, since everything is relegated to single account logins until you get to the higher levels. They have come out with a paid feature to remedy this, but I have not had a chance to fully review it yet to know if it fixes the access problem."
"In the last two years, there has been a certain amount of downtime when using the VDM."
"It would be beneficial for us if Cloudflare could offer a scrubbing solution. This would involve taking a snapshot of my website and keeping it live during a DDoS attack, ensuring uninterrupted service for our users. DDoS attacks are typically short in duration, and having Cloudflare maintain the site's availability from its secure network would enhance the overall user experience. I would appreciate it if Cloudflare could consider implementing this feature. Many organizations already utilize similar capabilities in their CDN platforms, where a static snapshot of the web page is displayed during DDoS attacks. In terms of features, Cloudflare needs to enhance its resilience and stay more focused on adopting new technologies. For instance, solutions like F5 XC Box, Access Solution, and Distributed Cloud Solution have impressive features, and Cloudflare should strive to match and exceed those capabilities. There's a need for improvement in areas like AI-based DDoS attacks and Layer 7 WAF features. Cloudflare should prioritize enhancements in areas such as behavioral DDoS and protection against SQL injection attacks, considering the prevalent trend of public exposure to the internet for business reasons. Overall, Cloudflare needs to invest more in advancing its feature set."
"I believe they currently have this feature, but there will most likely be integration with APIs so we can control some features through API."
"There might be helpful if there was some web application firewall feature."
"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."
"The product needs to improve its automation."
"We have noticed multiple instances where Cloudflare falsely indicates that our servers are down, even when there is no actual load on them. This makes it challenging for us to identify the exact issue."
"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."
"F5 Silverline Managed Services can improve by reducing the price."
"There is room for improvement in the stability of the solution."
"F5 Silverline Managed Services can improve by adding features that Palo Alto has."
"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."
"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."
"We need to have support for cloud protection, which is not offered by this solution."
"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 needs to be more reporting."
"Radware should focus on customization and integration, allowing routers and firewalls from other parties to integrate with the DDoS solution, enhancing security."
"I would like to have more granular steps according to protected bandwidth, so the granularity should be better."
"We heavily relied on Radware's technical team to ensure the proper setup and configuration of VPN tunnels for cloud mitigation."
"They should add artificial intelligence to the platform. It is currently missing the machine learning piece."
"It currently takes about 15 to 20 minutes for the process to complete, which should be minimized."
"I had some trouble in the registration account prior to deployment, but it was fixed. They were not very fast or responsive, however. It took about one week to resolve the issue."
"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."
 

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 tool is a premium product, so it is very expensive."
"The price is reasonable."
"Cloudflare's pricing is not much higher and is good for middle-level organizations."
"For Cloudflare, I recommend it heavily for small businesses with revenue under a couple of million dollars. Onboarding is easy, and they even have a free plan. This makes it simple for businesses in the $100,000-$500,000 range to try it out and see its value, allowing them to scale up their infrastructure as needed."
"I give the price a five out of ten."
"There are no additional costs beyond the standard licensing fees."
"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."
"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 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's switch to a pay-as-you-go model last year provides great flexibility."
"The NetFlow security could be improved too."
"The product's pricing is a good value."
"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."
"Radware Cloud DDoS is very expensive."
"The licensing cost is about $50,000."
"The pricing is okay, and I do not have any concerns about the price."

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).
