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

"This solution does a good job of preventing web application attacks, SQL injections, and cross-site scripting attacks."
"The most valuable part of the solution for us overall is exactly that it is a Software-as-a-Service product."
"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."
"Cloudflare is cheaper compared to Azure WAF, which I have considered before."
"We like that there's load balancing, firewall capabilities, DDoS protection, et cetera, all covered by Cloudflare."
"The stability of Cloudflare Web Application Firewall deserves a perfect 10 out of 10."
"Caching is the most valuable feature of Cloudflare Web Application Firewall."
"The integration of Cloudflare with Cloud Suite is its most valuable feature."
"AWS is very user-friendly and largely inexpensive, however, if an organization has the budget, there are lots of great products out there that do largely the same thing."
"The product’s availability, ease of configuration, and documentation are valuable."
"It's simple, easy to use."
"The most valuable feature of the solution is the ability to integrate central sets. It protects from intrusion attacks such as scripting and SQL injections."
"AWS WAF has a lot of integrated features and services. For example, there are security services that can be integrated very well for our customers."
"The initial setup was very straightforward. Deployment took about ten minutes or less."
"The most valuable aspect is that it protects our code. It's a bit difficult to overwrite code in our application. It also protects against threats."
"The most valuable feature is the capability to limit access based on geographical location by restricting specific IP addresses."
"The three most valuable features that I noticed are the geo-localization of the user, the IP reputation, and the compartmental analysis."
"By publishing the application without fear, my customer has created new revenue by making the website available anytime and anywhere."
 

Cons

"The blocked logs are difficult to read at times."
"Their documentation could be better. They don't have documentation that explains everything well."
"Support can be challenging at times."
"Cloudflare Web Application Firewall should include port forwarding features."
"The product can improve by having more multitenancy capability, which is currently not available."
"There could be an option to duplicate the cluster to maintain the consistency of rules."
"The accuracy of the Cloudflare Web Application Firewall could be improved by reducing the number of false-negative alerts."
"They have some limitations with third-party integrations."
"The product must provide more features."
"It is sometimes a lot of work going through the rules and making sure you have everything covered for a use case. It is just the way rules are set and maintained in this solution. Some UI changes will probably be helpful. It is not easy to find the documentation of new features. Documentation not being updated is a common problem with all services, including this one. You have different versions of the console, and the options shown in the documentation are not there. For a new feature, there is probably an announcement about being released, but when it comes out, there is no actual documentation about how to use it. This makes you either go to technical support or community, which probably doesn't have an idea either. The documentation on the cloud should be the latest one. Finding information about a specific event can be a bit challenging. For this solution, not much documentation is available in the community. It could be because it is a new tool. Whenever there is an issue, it is just not that simple to resolve, especially if you don't have premium support. You have pretty much nowhere to look around, and you just need to poke around to try and make it work right."
"There is room for improvement in pricing."
"The solution's pricing could be improved."
"The product could be improved by expanding the weightage units of rules we have when writing policy."
"The solution can improve its price."
"AWS WAF could improve by making the overall management easier. Many people that have started working with AWS WAF do not have an easy time. They should make it easy to use."
"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."
"The area that should be improved is licensing."
 

Pricing and Cost Advice

"Cloudflare offers different types of subscriptions for businesses, enterprises, and personal users, and the pricing is negotiable."
"We pay $210 per month for CloudFlare WAF."
"The annual licensing fee is $10,000 USD."
"Cloudflare Web Application Firewall is more affordable than other solutions."
"The solution's pricing option needs to be more transparent for enterprise clients."
"It is not too pricey."
"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."
"The pricing should be more affordable, especially as it pertains to small clients."
"We are kind of doing a POC comparison to see what works best. Pricing-wise, AWS is one of the most attractive ones. It is fairly cheap, and we like the pricing part. We're trying to see what makes more sense operation-wise, license-wise, and pricing-wise."
"There are different scale options available for WAF."
"The solution is affordable."
"It's cheap."
"AWS WAF has reasonable pricing."
"I rate the product price a five on a scale of one to ten, where one is high price, and ten is low price"
"The price of AWS WAF is reasonable, it is not expensive and it is not cheap."
