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 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."
"This solution does a good job of preventing web application attacks, SQL injections, and cross-site scripting attacks."
"Caching is the most valuable feature of Cloudflare Web Application Firewall."
"Some of the most valuable features of Cloudflare Web Application Firewall include its DNS zone setup and the zero trust policy."
"The integration of Cloudflare with Cloud Suite is its most valuable feature."
"This is a good product; it's reliable and scales well."
"The solution protects our application, which runs on the HTTP protocol, from DDoS attacks."

"The product's initial setup phase was very simple."

"By publishing the application without fear, my customer has created new revenue by making the website available anytime and anywhere."

Cons

"If they add logs history within the Cloudflare offering, that would be a great benefit."
"It would be ideal if the solution offered better log integration and more integration with different platforms."
"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."
"The user interface is very simple and straightforward, but users need knowledge about DNS to accomplish tasks."
"Cloudflare Web Application Firewall should include port forwarding features."
"It would be ideal if the solution offered better log integration and more integration with different platforms."
"They have some limitations with third-party integrations."
"The serverless product from AWS WAF could be improved. For example, they have only one serverless series, Lambda, but they should extend and improve it. Additionally, the firewall rules are not very easy to configure."
"We need more support as we go global."
"It would be good if the solution provided managed WAF services."
"They have to do more to improve, to innovate more features."
"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."
"On the UI side, I would like it if they could bring back the geolocation view on the corner."
"In a future release I would like to see automation. There's no interaction between the applications and that makes it tedious. We have to do the preparation all over again for each of our other applications."
"It's a bit difficult to apply the right rules for the right security."
"The area that should be improved is licensing."
"The area that should be improved is licensing."
