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

"Someone with a basic understanding of networking and security will be able to implement the firewall's basic features within 15 minutes."
"The rate limiting features and customizations in terms of URL match and applying policies are valuable to me."
"There is a huge signature repository"
"In general, it's a very good product: the solution is very stable, the performance is great, the product offers very good scalability, the pricing is very reasonable, the installation is very straightforward and quite simple, and technical support has a very fast response time and is helpful."
"Technical support has a very fast response time and they are helpful."
"This solution does a good job of preventing web application attacks, SQL injections, and cross-site scripting attacks."
"The stability of Cloudflare Web Application Firewall deserves a perfect 10 out of 10."
"The most valuable part of the solution for us overall is exactly that it is a Software-as-a-Service product."
"This solution is an enterprise-class firewall that provides both load-balancing and security, and once it's deployed, it works smoothly and without issue."
"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."
"We can monitor IP locations, but we have constraints from each country, it has a replication feature, and licenses can be shared, taking turns with each license."
"I would recommend this solution; it would be the best solution for WAF."
"Identification, ease of use, and ease of modifying it to most of our needs are valuable."
"The product has valuable features for load balancing, monitoring tools, and HPXpress services."
"It's scalable and very easy to manage."
"The threat intelligence function is great."
"I would give Radware Kubernetes WAF a rating of 10 out of 10."
 

Cons

"They have some limitations with third-party integrations."
"The rate limiting functionality could be enhanced, as we find it somewhat limited."
"The notification part could be improved. It's very much connected to Web Application Firewall, rate-limiting, and DDoS protection."
"They have some limitations with third-party integrations."
"Cloudflare Web Application Firewall should include port forwarding features."
"There could be an option to duplicate the cluster to maintain the consistency of rules."
"The reporting could be more granular."
"The product can improve by having more multitenancy capability, which is currently not available."
"You have to buy another module with an extra license to have the authentication feature."
"The contextual-based component needs a lot of help to catch up with the next-gen products."
"My experience with the technical support from F5 is that on the technical side, we sometimes face issues with reachability and availability."
"My advice to future customers of F5 Advanced WAF or to people thinking of using it is that there is a much better product in the market."
"I would say their graphical interface, the GUI. I don't like the GUI as much as before."
"The Sandbox integration feature could be improved."
"They could provide better pricing."
"The pricing could be more flexible."
"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

"The annual licensing fee is $10,000 USD."
"Cloudflare Web Application Firewall is more affordable than other solutions."
"It is not too pricey."
"Cloudflare offers different types of subscriptions for businesses, enterprises, and personal users, and the pricing is negotiable."
"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 solution's pricing option needs to be more transparent for enterprise clients."
"It starts at $20 and can easily go up to $200 monthly"
"The pricing model is very straightforward compared to the competition. You just pay per month for the product and usage."
"F5 bundles up services and the bundle is what you pay for rather than individual components."
"I am not sure about pricing but licenses are available on Google."
"After buying the program, you just pay for the support every year."
"Licensing fees for this solution are paid on a yearly basis."
"There is a perpetual license that comes with your hardware. There is also an additional fee for support."
"F5 Advanced WAF technical support comes at a cost, and it's expensive."
"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."
"The price of F5 Advanced WAF could improve it is expensive."
