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

"There is a huge signature repository"
"It is a SaaS solution unlike much of the competition."
"The integration of Cloudflare with Cloud Suite is its most valuable feature."
"The security features are valuable. The particular feature we use is called OWASP."
"The most valuable part of the solution for us overall is exactly that it is a Software-as-a-Service product."
"Very glad the WAF rulesets works out of box, and requires very little tuning or maintenance."
"The product has a valuable security control functionality."
"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."
"AWS WAF is something that someone from a cloud background or cloud security background leverages. If they want to natively use a solution in the cloud, AWS WAF comes in handy. It's very useful for that, and the way we can fine-tune the WAF rules is also nice."
"AWS WAF helps us a lot to make sure that the right customer gets the right access to the system."
"The automation of blocking for security attacks is valuable, with AWS applying rate limiting."
"The simple configuration and the scalability have been most valuable, and we are able to scale across all of our different AWS instances."
"The ability to take multiple data sets and match those data sets together is the solution's most valuable feature."
"The customized billing is the most valuable feature."
"I'm satisfied with AWS WAF, and I've had no issues with it."
"The stability of AWS WAF is valuable."
"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

"They need to improve their support because getting a response for basic requests took around 48 hours, which is too long."
"We have noticed some latency when the call goes through the firewall. That could be improved."
"Support can be challenging at times."
"The accuracy of the Cloudflare Web Application Firewall could be improved by reducing the number of false-negative alerts."
"The blocked logs are difficult to read at times."
"Cloudflare Web Application Firewall should include port forwarding features."
"The product can improve by having more multitenancy capability, which is currently not available."
"It would be ideal if the solution offered better log integration and more integration with different platforms."
"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."
"However, it'll be better for us if we could have some more documented guidelines on how the specific business should be structured and the roles that the cloud recommends."
"They have to do more to improve, to innovate more features. They need to increase the security. It has to be more active in detecting threats."
"There is a lot of innovation talk, however, implementation might be lacking."
"We need more support as we go global."
"The product could be improved by expanding the weightage units of rules we have when writing policy."
"One area that could be improved is the DDoS protection."
"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."
"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."
"It is not too pricey."
"The solution is expensive."
"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."
"Cloudflare Web Application Firewall is more affordable than other solutions."
"The solution's pricing option needs to be more transparent for enterprise clients."
"Its price is fair. There is a very fair amount that they charge. It has a pay-as-you-go model, so it pretty much depends on how much a user uses it. As per the cloud norms, the more you use, the more you pay. I would rate it a five out of ten in terms of pricing."
"It's cheap."
"There are no costs in addition to the standard licensing fees."
"AWS WAF is pay-as-you-go, I only pay for what I'm using. There is no subscription or any payment upfront, I can terminate use at any time. Which is an advantage."
"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 product is moderately priced."
"There are no separate licensing costs we pay for since it is included in the plan we purchase."
"AWS WAF has reasonable pricing."
