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 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."
"The setup process is very simple for me."
"Very glad the WAF rulesets works out of box, and requires very little tuning or maintenance."
"For us, the key feature of Cloudflare is DDoS protection and IP hiding, especially since we are a crypto company."
"The most valuable part of the solution for us overall is exactly that it is a Software-as-a-Service product."
"It is a SaaS solution unlike much of the competition."
"This is a good product; it's reliable and scales well."
"Overall, this is a good product and I recommend it."
"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."
"It is a one-click WAF with no effort needed."
"The performance is excellent."
"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 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 web solution effectively protects from vulnerabilities and cyber attacks."
"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 notification part could be improved. It's very much connected to Web Application Firewall, rate-limiting, and DDoS protection."
"Support can be challenging at times."
"The learning curve was steep initially."
"The solution's learning curve can still be further reduced"
"The blocked logs are difficult to read at times."
"Cloudflare Web Application Firewall should include port forwarding features."
"Cloudflare should update the version of the ModSecurity core rule set that they run on."
"The accuracy of the Cloudflare Web Application Firewall could be improved by reducing the number of false-negative alerts."
"The product should improve the DDoS-related features."
"Alternative WAFs have something like bot mitigation or bot control within the WAF, but you don't have such things in AWS WAF."
"This solution could be improved if the configuration steps were more specific to WAF, compared to other cloud services."
"The solution can improve its price."
"The pricing model is complicated."
"When users choose the free service, there isn't great support available to them."
"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."
"We don't have much control over blocking, because the WAF is managed by AWS."
"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 solution is expensive."
"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."
"It starts at $20 and can easily go up to $200 monthly"
"It is not too pricey."
"We pay $210 per month for CloudFlare WAF."
"Cloudflare Web Application Firewall is more affordable than other solutions."
"The solution's pricing option needs to be more transparent for enterprise clients."
"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."
"The price is average."
"There are no separate licensing costs we pay for since it is included in the plan we purchase."
"The solution is affordable."
"It's quite affordable. It's in the middle."
"It's cheap."
"For Kubernetes microservices, AWS is more expensive compared to OCI. AWS costs approximately 70 cents per hour, while OCI is 50% cheaper."
"There are no costs in addition to the standard licensing fees."
