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

"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."
"It is a SaaS solution unlike much of the competition."
"The solution protects our application, which runs on the HTTP protocol, from DDoS attacks."
"Cloudflare WAF provides protection through rules and functionalities like Cloudflare's SDRAP."
"The security features are valuable. The particular feature we use is called OWASP."
"Some of the most valuable features of Cloudflare Web Application Firewall include its DNS zone setup and the zero trust policy."
"The initial setup process is simple."
"The impact of Cloudflare Web Application Firewall's integration with existing web technologies on our site's performance and security measures is quite great, actually."
"The customizable features are good."
"The interface is good."
"The most valuable feature is the scalability because it automatically scales up or scales down as per our requirements."
"The ability to take multiple data sets and match those data sets together is the solution's most valuable feature."
"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 most valuable feature is the ability to use the product to enhance security in deploying web applications."
"It's simple, easy to use."
"I like the scalability, as it provides platform, infrastructure and software as a service."
"By publishing the application without fear, my customer has created new revenue by making the website available anytime and anywhere."
"The three most valuable features that I noticed are the geo-localization of the user, the IP reputation, and the compartmental analysis."
 

Cons

"They have some limitations with third-party integrations."
"I have experienced some difficulties with Cloudflare's support as a customer based in India."
"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."
"They have some limitations with third-party integrations."
"The solution's learning curve can still be further reduced"
"It would be ideal if the solution offered better log integration and more integration with different platforms."
"It would be ideal if the solution offered better log integration and more integration with different platforms."
"We have noticed some latency when the call goes through the firewall. That 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 pricing should be more affordable, especially as it pertains to small clients."
"The price could be improved."
"The solution can improve its price."
"This solution could be improved if the configuration steps were more specific to WAF, compared to other cloud services."
"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 find the documentation somewhat complex to implement during the initial stages."
"The dashboarding could be improved, and the default metrics provided by AWS WAF could be upgraded."
"The area that should be improved is licensing."
"The area that should be improved is licensing."
 

Pricing and Cost Advice

"The solution is expensive."
"Cloudflare Web Application Firewall is more affordable than other solutions."
"The annual licensing fee is $10,000 USD."
"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."
"We pay $210 per month for CloudFlare WAF."
"It is not too pricey."
"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."
"The solution is affordable."
"The pricing should be more affordable, especially as it pertains to small clients."
"It has a variable pricing scheme."
"It's an annual subscription."
"I would rate AWS WAF's pricing a seven out of ten."
"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"
"AWS is not that costly by comparison. They are maybe close to $40 per month. I think it was between $29 or $39."
"AWS WAF has reasonable pricing."
