Advanced security reporting has protected high-traffic betting platforms from constant attacks
I don't see room for improvement to Cloudflare Web Application Firewall. One thing I don't know much about because we have a dedicated IT team for that, and I'm not involved with Cloudflare much anymore. But if I were to compare them to F5, I would like to see more features that F5 offers. F5 has an option to bring the whole infrastructure, the whole WAF and all their packages, Bot Management, and everything else on your infrastructure. You need to install certain services from their side, and then you can choose if you would like requests to hit your servers immediately or if requests need to be proxied through F5 backbone. That would be a nice addition because we have 90% of the traffic as legit traffic coming from whitelisted servers. If it comes from whitelisted servers, I don't need to go every request through the backbone; I could easily just IP whitelist everything. Then I could maybe have Bot Management on my infrastructure that drastically reduces the price of Cloudflare. I would like to see Push CDN more improved in the next release of Cloudflare Web Application Firewall. And maybe something similar to Pushpin that Fastly has, which is an option where you can push messages that then can be scaled globally over the network. From our perspective, if we have a listener that listens for stock updates, I would just need to have one processor that pushes those updates to the Cloudflare API, and then Cloudflare would broadcast that message to all listeners. Cloudflare will check the order of the message, and if you, as a customer, are not connected or have some kind of network issue, when you reconnect, you will receive the latest state and missing updates.

Granular security policies have protected critical applications and ensure safe user and admin access
Improvements could be made regarding the log information from the backend CLI. There are enhancements needed; if a request gets blocked on the TCP layer, there should be traces or data to verify which source generated these requests, including the source and port information for initiation. These data are missing from F5 Advanced WAF. Besides that, another improvement could be refining the bot detection to minimize false positives; it should be able to verify more granularly between legitimate and non-legitimate clients. Overall, I find everything else good. A wish list feature I have is for the Technical Assistance Center (TAC) to respond more promptly. Their response time needs improvement; while they do not take excessive time, it can be enhanced, especially given it is a security product.

Quotes from Members

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

Pros

"The solution protects our application, which runs on the HTTP protocol, from DDoS attacks."
"For us, the key feature of Cloudflare is DDoS protection and IP hiding, especially since we are a crypto company."
"We extensively use the solution every day. The solution is very stable; we haven’t seen any glitches."
"Very glad the WAF rulesets works out of box, and requires very little tuning or maintenance."
"The stability of Cloudflare Web Application Firewall deserves a perfect 10 out of 10."
"There is a huge signature repository"
"The most valuable part of the solution for us overall is exactly that it is a Software-as-a-Service product."
"The integration of Cloudflare with Cloud Suite is its most valuable feature."
"F5 Advanced WAF secures our connectivity and combines both the main functions of WAF (balancing and web application security)."
"Overall, F5 Advanced WAF is a strong, dependable enterprise solution that works best when seen as a long-term security platform rather than a quick add-on; once properly designed, sized, and tuned, it runs quietly in the background and effectively does its job without constant attention."
"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."
"F5 Advanced WAF has very good stability and scalability, and its initial setup was straightforward."
"The technical support is perfect."
"The whole mechanism of F5 Advanced WAF is effective."
"The most valuable features of F5 Advanced WAF are the balancer and you can change policies very easily."
"iRules are quite appealing when it comes to F5."
"I would give Radware Kubernetes WAF a rating of 10 out of 10."
 

Cons

"The user interface is very simple and straightforward, but users need knowledge about DNS to accomplish tasks."
"The platform's control features related to real-time authentication and response time need improvement."
"The ModSecurity core rules need to be updated."
"A key challenge arises when dealing with numerous integrations with HVAC systems. Depending on the specifics, there might be some configuration mismatches, which necessitate specific support."
"They have some limitations with third-party integrations."
"Their documentation could be better. They don't have documentation that explains everything well."
"If they add logs history within the Cloudflare offering, that would be a great benefit."
"The product can improve by having more multitenancy capability, which is currently not available."
"F5 Advanced WAF could improve on its funding for WAF features. There is a need to be more advanced WAF features."
"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 protection against web page attacks like what is available in FortiWeb."
"For me, an area for improvement in F5 Advanced WAF is the reporting as it isn't so clear."
"Compatibility with multiple cloud environments needs improvement. Both stability and scalability need to be improved."
"All features of Advanced WAF offer numerous functions, which means tuning configuration is not simple."
"We get false positives sometimes."
"There should be more ability to rate limit certain scenarios."
"If Radware provides a separate web service like those offered by vendors such as F5 and Imperva, that would be better."
 

Pricing and Cost Advice

"It starts at $20 and can easily go up to $200 monthly"
"What's my experience with pricing, setup cost, and licensing? I believe the pricing is not the best, but it's reasonable and acceptable. We also use the McAfee system in parallel. In terms of pricing, its okay - not great, but not bad either. It falls in the middle, which is acceptable. In terms of support licensing, last time, we were searching for a solution, and we considered products from resellers rather than directly from the cloud provider. However, the pricing we encountered was exceptionally high. As a result, we are inclined to select support from the reseller."
"The annual licensing fee is $10,000 USD."
"We pay $210 per month for CloudFlare WAF."
"Cloudflare Web Application Firewall is more affordable than other solutions."
"The solution is expensive."
"The pricing model is very straightforward compared to the competition. You just pay per month for the product and usage."
"Cloudflare offers different types of subscriptions for businesses, enterprises, and personal users, and the pricing is negotiable."
"The way we deployed it, I would rate it a four out of five in terms of pricing."
"There are various plans available for Fortinet FortiWeb Cloud WAF as a Service, including a trial version."
"It is a little bit costly, but it has all the features that are required."
"Its price is fair. We have done a couple of deals where they were able to give some kind of discount to the customers. The price was initially high for the customers, but after a couple of negotiations, it came within their budget. They were happy with that."
"I am not sure about pricing but licenses are available on Google."
"After buying the program, you just pay for the support every year."
"I don't have any issue with the pricing of this solution."
"The price of F5 Advanced WAF could improve it is expensive."
