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

"It is configurable via API."
"Some of the most valuable features of Cloudflare Web Application Firewall include its DNS zone setup and the zero trust policy."
"The Cloudflare Web Application Firewall's most valuable feature is its ease of configuration."
"This solution does a good job of preventing web application attacks, SQL injections, and cross-site scripting attacks."
"This is a good product; it's reliable and scales well."
"Very glad the WAF rulesets works out of box, and requires very little tuning or maintenance."
"Caching is the most valuable feature of Cloudflare Web Application Firewall."
"The product has a valuable security control functionality."
"WAF functionality is valuable for protecting applications from attacks."
"It's scalable and very easy to manage."
"Despite a few issues, F5 Advanced WAF is performing well for me."
"The solution is easily accessible on mobile and laptop devices."
"The most valuable features of F5 Advanced WAF are the overall capabilities, there is not a comparable solution on the market."
"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."
"F5 technical support is excellent. They are experts who always provide the right solution, and they understand the problem. Their response and resolution times are good."
"In terms of F5 Advanced WAF's most valuable features, I would definitely say its stability, as F5 is one of the most stable products and either as the load balancer or the web application firewall, it is very stable."
"I would give Radware Kubernetes WAF a rating of 10 out of 10."
 

Cons

"It would be ideal if the solution offered better log integration and more integration with different platforms."
"The dashboard could be more user-friendly."
"Cloudflare should update the version of the ModSecurity core rule set that they run on."
"The blocked logs are difficult to read at times."
"They have some limitations with third-party integrations."
"If they add logs history within the Cloudflare offering, that would be a great benefit."
"There could be an option to duplicate the cluster to maintain the consistency of rules."
"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."
"The Sandbox integration feature could be improved."
"F5 Advanced WAF could improve the reporting. It's a bit difficult to populate, them. If you're not so familiar with the functions, such as where to find the logs and other settings."
"The solution is very expensive so should only be used in the right environment."
"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."
"The contextual-based component needs a lot of help to catch up with the next-gen products."
"For F5 Advanced WAF, it's only 70% different over time with upgrades. F5 can still build AWS support after many long years of absence."
"I would like to see a better interface and better documentation compatibility with other products. It's more complicated with OWASP."
"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."
"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

"Cloudflare Web Application Firewall is more affordable than other solutions."
"We pay $210 per month for CloudFlare WAF."
"The solution's pricing option needs to be more transparent for enterprise clients."
"The annual licensing fee is $10,000 USD."
"The pricing model is very straightforward compared to the competition. You just pay per month for the product and usage."
"The solution is expensive."
"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."
"Cloudflare offers different types of subscriptions for businesses, enterprises, and personal users, and the pricing is negotiable."
"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."
"The price of the solution is reasonable when compared with other products, such as FortiWeb. I am very satisfied with the price."
"The cost is slightly above average."
"Licensing fees for this solution are paid on a yearly basis."
"The price of F5 Advanced WAF could improve it is expensive."
"A yearly license for F5 Advanced WAF is 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."
"As far as the pricing of F5 Advanced WAF I would rate it a four out of five depending on what features I am looking for. Imperva is more expensive."
