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.

Rapid attack detection and traffic visibility improve security management
The solution was intended for the big clients of Telefonica to clean their internet pipe. We deployed the service to clean the pipe. In some clients' data centers, we implemented a solution that detects and mitigates attacks using Arbor DDoS, our data center solution For me, the most valuable…

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 tool is user-friendly."
"It's very user-friendly."
"Its ease of integration with Office 365 and the fact that it's a good product compared to what I had before"
"It is easier to configure and develop documentation to see how we have configured firewalls."
"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."
"We're using dynamic components to build flexible pages to create and manage Git merge requests for code and reviews."
"It is a fast and secure DNS."
"The solution is stable, and the DNS servers are simple to use."
"Arbor DDoS offers security features that automatically detect and prevent DDoS attacks."
"Its scalability is big. It is for large deployments of big organizations and service providers."
"Arbor DDoS's best feature is that we can put the certificates in, and it will look at layer seven and the encrypted traffic and do the required signaling."
"Predefined filters/techniques to easily stop the attacks and start mitigation."
"It has an easy-to-understand GUI...Stability-wise, I rate the solution a ten out of ten."
"There are a number of valuable features in this product, like Cloud Signaling and Threat Intelligence feeds."
"In the GUI, the packet capture is a very good option, as is the option to block an IP address."
"Arbor has the ability to learn and self-create the appropriate profile for each customer."
"The most valuable feature of F5 Silverline Managed Services is the benchmark performance."
"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."
"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 best advantage of F5 Silverline Managed Services is that it is easy to use."
"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."
"F5 technical support is really good."
"It's a good front end for public infrastructure"
"The initial setup is straightforward."
 

Cons

"Sometimes their more advanced caching tools can cause higher first-byte times and problems with JavaScript."
"The pricing could be improved."
"Technical support is lacking."
"There should be a specific price list for enterprise-level customers."
"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."
"The timing aspect can lead to it being considered overpriced. This is a particular concern we have with Cloudflare, as they may struggle with accurately detecting the client."
"Latencies are always a problem."
"It should have easier documentation for the configuration. It's very technical and people who aren't technical should also be able to do the configuration."
"For troubleshooting problems, it's not so intuitive. It's not straightforward. This is the core of their kernel, so they need to improve it a little bit... In F5 I have full control of everything."
"I would also like more visibility into their bad actor feeds, their fingerprint feeds. We try to be good stewards of the internet, so if there are attacks, or bad actors within our networks, if there were an easier way for us to find them, we could stop them from doing their malicious activity, and at the same time save money."
"Arbor DDoS could improve out-of-the-box reporting, it could be better."
"We need a SaaS model for the solution."
"The following areas need improvement: opening and tracking support tickets, online support resources, software upgrades/updates and replacement media, and event management guidelines."
"The implementation should be made easier."
"An improvement to Arbor DDoS would be to make evaluation licenses and virtual machines available."
"A small improvement could be a better reporting system."
"We need to have support for cloud protection, which is not offered by this solution."
"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 reducing the price."
"You need to have Linux knowledge in order to use the shell."
"The price is high in comparison to other products."
"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."
"There is room for improvement in the stability of the solution."
 

Pricing and Cost Advice

"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."
"The solution is expensive when compared to other products but offers unlimited bandwidth."
"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 depends on the usage, but the cheapest would be around 5,000 USD a month."
"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."
"We are using the free tier of the solution."
"The product's pricing is minimal compared to other products."
"Pricing is slightly on the higher side."
"It is an expensive product. I use this product for its different features."
"The price of Arbor DDoS depends on many parameters. It depends on the physical capacity of the environment, and it is not a straight-line price. It's fairly competitive in the market on the price."
"Regarding pricing, I would rate it as average. Arbor DDoS offers good value for money with our DDoS filter device. For higher protection needs, Arbor’s CloudMeter’s DDoS mitigation or hardware devices might be more expensive, but customers who need them are usually prepared for the cost and the additional resources required."
"The price is a little high."
"Arbor is striking a good balance between pricing and what they deliver."
"Our customers always complain about the price of the product."
"The solution's pricing is based on a licensing model that is expensive when compared to other tools."
"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."
"The product’s pricing is reasonable."
"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."
