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 setup process is very simple for me."
"For us, the key feature of Cloudflare is DDoS protection and IP hiding, especially since we are a crypto company."
"We extensively use the solution every day. The solution is very stable; we haven’t seen any glitches."
"Very glad the WAF rulesets works out of box, and requires very little tuning or maintenance."
"The stability of Cloudflare Web Application Firewall deserves a perfect 10 out of 10."
"In general, it's a very good product: the solution is very stable, the performance is great, the product offers very good scalability, the pricing is very reasonable, the installation is very straightforward and quite simple, and technical support has a very fast response time and is helpful."
"I have not had any issues with this solution, and I would recommend it to others who are interested in using it."
"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."
"The most valuable feature of AWS WAF is the extra layer of security that I have when connecting to my web applications."
"One common use case is using detection protection for enhancing security models in AWS. Another use case is implementing log analysis and response recovery procedures for email services."
"AWS WAF is a stable solution. The performance of the solution is very good."
"The most valuable feature is the security, making sure that files are protected, preventing unauthorized users from accessing the system."
"The security firewall plus the features that protect against database injections or scripting,"
"As a basic WAF, it's better than having nothing, so if you need something simple out of the box with default features, AWS WAF is good."
"I believe the most impressive features are integration and ease of use, and the best part of AWS WAF is the cloud-native WAF integration, where AWS maintains everything and all we have to do is click the button and WAF will be activated so any packet coming through the internet will be filtered through."
"AWS has flexibility in terms of WAF rules."
"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

"Cloudflare should update the version of the ModSecurity core rule set that they run on."
"Its stability could be better."
"Cloudflare Web Application Firewall should improve visibility for a customer."
"The accuracy of the Cloudflare Web Application Firewall could be improved by reducing the number of false-negative alerts."
"It would be ideal if the solution offered better log integration and more integration with different platforms."
"The product can improve by having more multitenancy capability, which is currently not available."
"The ModSecurity core rules need to be updated."
"The dashboard could be more user-friendly."
"The area of reporting in the product needs to have a proper format."
"One area that could be improved is the DDoS protection."
"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."
"I believe there is a need to move towards real-time analysis with the help of AI and intelligent systems in the future. This would reduce the reliance on manual work and enhance the functionality of detection protection. By incorporating AI-driven data analysis and data science techniques, we can improve the solution's user-friendliness, security compatibility, and accuracy."
"They should work to define more threats, add more security, and make it more compliant with more security companies."
"We must monitor and clean up the WAF manually."
"The solution's pricing could be improved."
"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."
"The area that should be improved is licensing."
"The area that should be improved is licensing."
 

Pricing and Cost Advice

"The solution is expensive."
"The annual licensing fee is $10,000 USD."
"Cloudflare offers different types of subscriptions for businesses, enterprises, and personal users, and the pricing is negotiable."
"The pricing model is very straightforward compared to the competition. You just pay per month for the product and usage."
"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 is not too pricey."
"The solution's pricing option needs to be more transparent for enterprise clients."
"Cloudflare Web Application Firewall is more affordable than other solutions."
"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."
"I rate the product price a five on a scale of one to ten, where one is high price, and ten is low price"
"There are no costs in addition to the standard licensing fees."
"I would rate AWS WAF's pricing a seven out of ten."
"You need an additional AWS subscription for this product if you are buying a managed tool."
"The price of AWS WAF is reasonable, it is not expensive and it is not cheap."
"On a scale from one to ten, where one is cheap and ten is expensive, I rate the solution's pricing a seven or eight out of ten."
"The pricing is good and manageable."
