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.

For improvement in AWS WAF, we can have better monitoring. One of the things that should be improved in AWS WAF is the monitoring; we need to identify the requests and where they are coming from. If it's a bot, we should differentiate the requests, whether they are automated or not. The way we see it now is just mentioned as a percentage from bots and actual users, which should include proper graphs and detailed information. We also need a feature where we can filter specific requests. If there are scripts in the requests, we should be able to filter those requests to see if there are any scripts running from them.

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

"We like that there's load balancing, firewall capabilities, DDoS protection, et cetera, all covered by Cloudflare."
"Cloudflare WAF provides protection through rules and functionalities like Cloudflare's SDRAP."
"Technical support has a very fast response time and they are helpful."
"The impact of Cloudflare Web Application Firewall's integration with existing web technologies on our site's performance and security measures is quite great, actually."
"The initial setup process is simple."
"Cloudflare has positively impacted my organization by making it easier for me to handle and set up DNS for multiple clients; I can easily go in and access their accounts, make changes they need, and it's a one-stop shop."
"It's pretty convenient and pretty easy to set up and run. And then kind of for static content, it also offers caching."
"This solution does a good job of preventing web application attacks, SQL injections, and cross-site scripting attacks."
"The cloud-native nature of AWS is crucial since most of our workload is in AWS, making AWS WAF native to Amazon Web Services."
"The interface is good."
"We can host any DB or application on the solution."
"The agility is great for us in terms of cloud services in general."
"One common use case is using detection protection for enhancing security models in AWS. Another use case is implementing log analysis and response recovery procedures for email services."
"AWS WAF acts as a barrier, analyzing HTTP communications between external users and web applications."
"I'm satisfied with AWS WAF, and I've had no issues with it."
"The most valuable feature is the way it blocks threats to external applications."
"By publishing the application without fear, my customer has created new revenue by making the website available anytime and anywhere."
"The three most valuable features that I noticed are the geo-localization of the user, the IP reputation, and the compartmental analysis."
 

Cons

"It would be ideal if the solution offered better log integration and more integration with different platforms."
"The platform's control features related to real-time authentication and response time need improvement."
"Its stability could be better."
"The reporting could be more granular."
"Their documentation could be better. They don't have documentation that explains everything well. They have documentation for everything you're looking for, but they lack a single piece of documentation to tie everything together. As a new user or beginner, it took us a little bit of time to figure out how to put all these things in place."
"The reporting could be improved if it were more granular."
"The accuracy of the Cloudflare Web Application Firewall could be improved by reducing the number of false-negative alerts."
"I have experienced some difficulties with Cloudflare's support as a customer based in India."
"The solution could improve by having better rules, they are very basic at the moment. There are more attacks coming and we have to use third-party solutions, such as FIA. The features are not sufficient to prevent all the attacks, such as DDoS. Overall the solution should be more secure."
"For now, there is no feature to protect against attack of the bad bots"
"This solution could be improved if the configuration steps were more specific to WAF, compared to other cloud services."
"On the UI side, I would like it if they could bring back the geolocation view on the corner."
"There is a lot of innovation talk, however, implementation might be lacking."
"The product should improve the DDoS-related features."
"The solution is cloud-based, and therefore the billing model that comes with it could be more intuitive, in my opinion."
"Alternative WAFs have something like bot mitigation or bot control within the WAF, but you don't have such things in AWS WAF."
"The area that should be improved is licensing."
"The area that should be improved is licensing."
 

Pricing and Cost Advice

"Cloudflare Web Application Firewall is more affordable than other solutions."
"The pricing model is very straightforward compared to the competition. You just pay per month for the product and usage."
"We pay $210 per month for CloudFlare WAF."
"The annual licensing fee is $10,000 USD."
"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 solution is expensive."
"It is not too pricey."
"The pricing should be more affordable, especially as it pertains to small clients."
"The price of AWS WAF is reasonable, it is not expensive and it is not cheap."
"The product is moderately priced."
"It's quite affordable. It's in the middle."
"AWS is not that costly by comparison. They are maybe close to $40 per month. I think it was between $29 or $39."
"There are no separate licensing costs we pay for since it is included in the plan we purchase."
"There are different scale options available for WAF."
"AWS WAF is pay-as-you-go, I only pay for what I'm using. There is no subscription or any payment upfront, I can terminate use at any time. Which is an advantage."
