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 solution protects our application, which runs on the HTTP protocol, from DDoS attacks."
"I'm highly satisfied. It's remarkably user-friendly, enabling me to quickly identify issues, and deploy solutions, and it offers the necessary features."
"We like that there's load balancing, firewall capabilities, DDoS protection, et cetera, all covered by Cloudflare."
"There is a huge signature repository"
"The initial setup process is simple."
"Cloudflare WAF provides protection through rules and functionalities like Cloudflare's SDRAP."
"The setup process is very simple for me."
"Technical support has a very fast response time and they are helpful."
"The most valuable feature is the ability to use the product to enhance security in deploying web applications."
"The most valuable feature is the scalability because it automatically scales up or scales down as per our requirements."
"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."
"The agility is great for us in terms of cloud services in general."
"The cloud-native nature of AWS is crucial since most of our workload is in AWS, making AWS WAF native to Amazon Web Services."
"This is not a product that you need to install. You just use it."
"They filter a lot of attacks out."
"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

"The product can improve by having more multitenancy capability, which is currently not available."
"A key challenge arises when dealing with numerous integrations with HVAC systems. Depending on the specifics, there might be some configuration mismatches, which necessitate specific support."
"If they add logs history within the Cloudflare offering, that would be a great benefit."
"Its stability could be better."
"The notification part could be improved. It's very much connected to Web Application Firewall, rate-limiting, and DDoS protection."
"The rate limiting functionality could be enhanced, as we find it somewhat limited."
"Support can be challenging at times."
"Cloudflare should update the version of the ModSecurity core rule set that they run on."
"The product must provide more features."
"The complexity of deploying turnkey solutions could be simplified."
"On the UI side, I would like it if they could bring back the conditions view which had geo match, IP sets and etc."
"The solution could improve by having better rules, they are very basic at the moment. There are more attacks coming and we have to use third-party solutions, such as FIA. The features are not sufficient to prevent all the attacks, such as DDoS. Overall the solution should be more secure."
"One area that could be improved is the DDoS protection."
"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."
"There is room for improvement in pricing."
"Support wise, I don't think they are that good compared to individual vendors."
"The area that should be improved is licensing."
"The area that should be improved is licensing."
 

Pricing and Cost Advice

"We pay $210 per month for CloudFlare WAF."
"Cloudflare offers different types of subscriptions for businesses, enterprises, and personal users, and the pricing is negotiable."
"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."
"Cloudflare Web Application Firewall is more affordable than other solutions."
"The solution is expensive."
"The pricing model is very straightforward compared to the competition. You just pay per month for the product and usage."
"The annual licensing fee is $10,000 USD."
"There are different scale options available for WAF."
"AWS WAF has reasonable pricing."
"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."
"AWS is not that costly by comparison. They are maybe close to $40 per month. I think it was between $29 or $39."
"It has a variable pricing scheme."
"The pricing is good and manageable."
"For our infrastructure, we probably pay around $16,000 per month for AWS WAF. Because alternative WAF solutions provide even more features, I think the AWS WAF is a bit pricey"
"The pricing should be more affordable, especially as it pertains to small clients."
