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

"The stability of Cloudflare Web Application Firewall deserves a perfect 10 out of 10."
"Some of the most valuable features of Cloudflare Web Application Firewall include its DNS zone setup and the zero trust policy."
"For us, the key feature of Cloudflare is DDoS protection and IP hiding, especially since we are a crypto company."
"The setup process is very simple for me."
"Technical support has a very fast response time and they are helpful."
"The integration of Cloudflare with Cloud Suite is its most valuable feature."
"The Cloudflare Web Application Firewall's most valuable feature is its ease of configuration."
"Caching is the most valuable feature of Cloudflare Web Application Firewall."
"AWS WAF is a stable solution. The performance of the solution is very good."
"Overall, this is a good product and I recommend it."
"The solution is stable."
"Because it integrates with the existing AWS solution, we get a lot of support without having to do much extra work."
"The ability to take multiple data sets and match those data sets together is the solution's most valuable feature. The data lake that comes with it is very useful because that allows us to match data sets with different configurations that we wouldn't normally be able to match."
"The product’s availability, ease of configuration, and documentation are valuable."
"The most valuable feature is the ability to use the product to enhance security in deploying web applications."
"It is a one-click WAF with no effort needed."
"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

"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."
"It would be ideal if the solution offered better log integration and more integration with different platforms."
"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."
"Cloudflare Web Application Firewall should improve visibility for a customer."
"Its stability could be better."
"The product can improve by having more multitenancy capability, which is currently not available."
"The notification part could be improved. It's very much connected to Web Application Firewall, rate-limiting, and DDoS protection."
"The default content policy available in the tool is not very strong compared to the competitors."
"On the UI side, I would like it if they could bring back the geolocation view on the corner."
"The setup is complicated."
"The user experience, the interface, is lacking. Sometimes it's hard to find certain areas that it has alerted on."
"They should work to define more threats, add more security, and make it more compliant with more security companies."
"It's a bit difficult to apply the right rules for the right security."
"Whenever there is an issue, it is just not that simple to resolve, especially if you don't have premium support."
"The cost must be reduced."
"The area that should be improved is licensing."
"The area that should be improved is licensing."
 

Pricing and Cost Advice

"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."
"Cloudflare Web Application Firewall is more affordable than other solutions."
"The solution's pricing option needs to be more transparent for enterprise clients."
"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."
"We pay $210 per month for CloudFlare WAF."
"It starts at $20 and can easily go up to $200 monthly"
"AWS WAF has reasonable pricing."
"AWS WAF has reasonable pricing."
"For Kubernetes microservices, AWS is more expensive compared to OCI. AWS costs approximately 70 cents per hour, while OCI is 50% cheaper."
"It has a variable pricing scheme."
"There are different scale options available for WAF."
"It's quite affordable. It's in the middle."
"The price is average."
"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."
