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.

Easy event identification, highly stable, and customizable

Generally, F5 Advanced WAF initial setup is straightforward. However, our environment was more complex and it took us a little more time to customize the solution to where we needed it to be. Additionally, the customization didn't rectify everything. We had to do customization to a certain event to prevent attacks that it wasn't catching, but that might not necessarily be the solutions' fault. It could be more of our setup than the solution's fault and not being able to run the latest version or the newer version could be more of a limitation on our ability to put it in the right place. The whole implementation to have the solution run at the level we wanted it to take approximately five months. Our company's environment is one that we can't put a canned solution in front of. Our environment, cannot have a canned solution that might fit everybody else because of how customized this environment is. It does need a lot of tuning to meet our environment's requirements. I rate the initial setup of F5 Advanced WAF a three out of five.

Geo-localization and IP reputation help to keep our clients secure and more available

The area that should be improved is licensing. When using an active/passive cluster, we have to pay 70% of the master appliance and license for the passive server that does not work. Since we know that only one server works at a time, we should pay only one license for the appliances and for the support as well. In my opinion, this has to be improved. If possible, the client software should be a web application instead of downloading software for the management. This can avoid login problems when they update or patch.

Quotes from Members

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

Pros

"It is a fast and secure DNS."

"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."

"Many websites require an SSL certificate because they sell stuff and want SSL. Cloudflare comes with an SSL certificate built in. It's automatic. You sign yourself up for Cloudflare, and an SSL certificate automatically protects your website. You don't necessarily need a certificate if you have a connection between your website and your host, the server, Cloudflare, and the host."

"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"

"The most valuable feature is its usability."

"DDoS attacks target unprotected machines. Cloudflare detects and stops these attacks using internal systems. It identifies incoming DDoS attacks, issuing challenges or blocking them immediately."

"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."

More Cloudflare pros

"It's scalable and very easy to manage."

"The most valuable features of F5 Advanced WAF are the easy identification of events and customization. We can pinpoint our settings."

"This solution inspects your traffic and based on that, automatically create distinct qualities for you, so you can add this to the policy already created. That's what I like most."

"The most valuable feature of F5 Advanced WAF is its grand unity of the implementation, where you have the freedom to configure based on how it affects your use case or your organization. With the default setting of implicit deny, you can gradually start defining and deploying the tool to align with your environment, whether it is outdated, recent, or futuristic. This allows you to customize the solution to protect you from threat actors. You have the ability to define what the advanced threat act should do - whether it should alert, deny, or both - and it will deliver based on your configuration. Unlike other online solutions, F5 Advanced WAF provides flexibility to deliver to your unique environment the way you want."

"Despite a few issues, F5 Advanced WAF is performing well for me."

"We can monitor IP locations, but we have constraints from each country. It has a replication feature. Licenses can be shared, taking turns with each license."

"The best solution for WAF."

"It can scale."

More F5 Advanced WAF pros

"The three most valuable features that I noticed are the geo-localization of the user, the IP reputation, and the compartmental analysis."

Cons

"The solution could be more user-friendly."

"There could be more courses with engineers. I like e-learning, however, having a specialist in a classroom is more comfortable for me."

"The product needs to improve its automation."

"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."

"There might be helpful if there was some web application firewall feature."

"Cloudflare's console should be made more user-friendly."

"Even if I wanted to, I wouldn't be able to buy Cloudflare in my country."

"The tool needs to improve caching of servers. The product needs to include PFX certificate as well."

More Cloudflare cons

"The product could be more user-friendly for administrators."

"They could provide better pricing."

"While F5 Advanced WAF does limit the number of partners in certain regions to ensure successful business transactions, they could also benefit from expanding their partnerships and making it easier for more people to learn about and become experts in F5 Advanced WAF. By doing so, they could increase the reach and exposure of their solution, similar to how Cisco has become widely recognized in the security industry."

"I would not expect traffic details to pass through the web application firewall across the length of the whole application. I think that there is a web application where it can let the application function without traffic going in into the WAF."

"The solution should include RASP for another level of protection at the code itself."

"It should be a little bit easy to deploy in terms of the overall deployment session. One of our customers is a bit unhappy about the reporting options. Currently, it automatically deletes event logs after some limit if a customer doesn't have any external Syslog server. It is a problem for those customers who want to review event logs after a week or so because they won't get proper reports or event logs. They should increase the duration to at least a month or two for storing the data on the device. F5 is not a leader in Gartner Quadrant, which affects us when we go and pitch this solution. Customers normally go and take a look at such annual reports, and because F5 is currently not there as a leader, the customers ask about it even though we are saying it is good in all things. F5 is not known for something totally different or unique. They were a major player in ADP, and they are just rebranding themselves into security. They should improve or increase their marketing as a security company now. They have already started to do that, but they should do it more so that when it comes to security, customers can easily remember F5. At the moment, if we say F5, load balancing comes to mind. With rebranding and marketing, all customers should get the idea that F5 is now mainly focusing on the security part of it, and it is a security company instead of load balancing. This is the first solution that should come to a customer's mind for a web application firewall."

"We usually use a third-party tool for logging and reporting. It would be nice if we could do that right on this solution. They have one, but it's not very stable. Logging and reporting effectively would be a big enhancement."

"Scalability could be improved."

More F5 Advanced WAF cons

"The area that should be improved is licensing."

Pricing and Cost Advice

"The pricing for the service is reasonable, neither excessively cheap nor prohibitively expensive. It aligns well with the value of their solution."

"The product's pricing is cheap."

"So far I use free tier and happy with it. You can subscribe to business package if needed."

"That is one of the great features. I was able to access the majority of the features and services for free."

"I give the price a five out of ten."

"The pricing depends on the usage, but the cheapest would be around 5,000 USD a month."

"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 price is reasonable."

More Cloudflare pricing and cost advice

"F5 Advanced WAF's pricing is high."

"There are various plans available for Fortinet FortiWeb Cloud WAF as a Service, including a trial version."

"The cost is slightly above average."

"There is a perpetual license that comes with your hardware. There is also an additional fee for support."

"The pricing for F5 Advanced WAF is comparable to a Rolls-Royce. Its price is a bit high when you compare it with other vendors. F5 Advanced WAF is a bit expensive. The customer was on a three-year plan and it was around $560,000."

"Pricing for this solution is higher than average."

"Licensing fees for this solution are paid on a yearly basis."

"The pricing is too high."

“What I like best about Cloudflare is that my company can use it to trace and manage
applications and monitor traffic. The solution tells you if there's a spike in traffic. Cloudflare
also sends you a link to check your equipment and deployment and track it through peering,
so it's a valuable tool.” Daniel P., Network Engineer at Ufinet

well through the interface. There is a lot of functionality that is embedded in the service.” PeerSpot user, Competence Center Manager at a tech services company
