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

"Cloudflare is cheaper compared to Azure WAF, which I have considered before."
"It's pretty convenient and pretty easy to set up and run. And then kind of for static content, it also offers caching."
"The stability of Cloudflare Web Application Firewall deserves a perfect 10 out of 10."
"The integration of Cloudflare with Cloud Suite is its most valuable feature."
"Technical support has a very fast response time and they are helpful."
"The rate limiting features and customizations in terms of URL match and applying policies are valuable to me."
"Some of the most valuable features of Cloudflare Web Application Firewall include its DNS zone setup and the zero trust policy."
"This solution does a good job of preventing web application attacks, SQL injections, and cross-site scripting attacks."
"Stable and scalable web application firewall. Setting it up is straightforward."
"The stability of AWS WAF is valuable."
"AWS WAF is very easy to use and configure on AWS."
"The product's initial setup phase was very simple."
"The tool’s stability is very good."
"The simple configuration and the scalability have been most valuable, and we are able to scale across all of our different AWS instances."
"AWS WAF helps mitigate different kinds of bot attacks and SQL injection that happen within the retail industry."
"The solution is stable."
"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

"Cloudflare Web Application Firewall should improve visibility for a customer."
"The platform's control features related to real-time authentication and response time need improvement."
"There could be an option to duplicate the cluster to maintain the consistency of rules."
"The user interface is very simple and straightforward, but users need knowledge about DNS to accomplish tasks."
"Their documentation could be better. They don't have documentation that explains everything well."
"Support can be challenging at times."
"They need to improve their support because getting a response for basic requests took around 48 hours, which is too long."
"We don't even use Cloudflare Bot Management because it's too expensive; you need to pay per request, and it's much cheaper to get one or two additional machines."
"They should make the implementation process faster."
"Rule exclusion could be a bit more transparent."
"While the complexity of the installation can vary from one service to another, overall, I would say that it and the configuration and navigation are somewhat complex."
"We don't have much control over blocking, because the WAF is managed by AWS."
"I would like to see it more tightly integrated with other AWS services."
"The pricing should be more affordable, especially as it pertains to small clients."
"The product could be improved by expanding the weightage units of rules we have when writing policy."
"The rate at which AWS updates their managed rule sets could be better. Features like bot protection or DDoS mitigation, available with other WAF vendors, do not come natively with AWS WAF."
"The area that should be improved is licensing."
 

Pricing and Cost Advice

"It starts at $20 and can easily go up to $200 monthly"

"The solution is affordable."
"There are no separate licensing costs we pay for since it is included in the plan we purchase."
"AWS WAF has reasonable pricing."
"The price of AWS WAF is expensive if you do not know how to manage your software up or down. I price of the solution is average amongst the other competitors but it would be better if it was less expensive."
