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 Cloudflare Web Application Firewall's most valuable feature is its ease of configuration."
"It's pretty convenient and pretty easy to set up and run. And then kind of for static content, it also offers caching."
"This solution does a good job of preventing web application attacks, SQL injections, and cross-site scripting attacks."
"Someone with a basic understanding of networking and security will be able to implement the firewall's basic features within 15 minutes."
"It protects web applications efficiently."
"There is a huge signature repository"
"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."
"It has improved our organization a lot because before we were having problems with access management, things have gotten better using this product, it is protecting the files, it has been the best step for us, we are no longer having problems with unauthorized access, where somebody breaches the system or compromises documents, and nothing like that has happened over the past year that we have been using this product."
"The ease of deployment of the product is valuable to me."
"It is Amazon. Everything is scalable. It is beyond what we need."
"It's simple, easy to use."
"We do not have to maintain the solution."
"AWS WAF is pay-as-you-go, I only pay for what I'm using; there is no subscription or any payment upfront, and I can terminate use at any time, which is an advantage."
"The solution's initial setup process is easy."
"AWS WAF has a lot of integrated features and services, for example, there are security services that can be integrated very well for our customers."
"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

"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."
"I have experienced some difficulties with Cloudflare's support as a customer based in India."
"There could be an option to duplicate the cluster to maintain the consistency of rules."
"The accuracy of the Cloudflare Web Application Firewall could be improved by reducing the number of false-negative alerts."
"The accuracy of the Cloudflare Web Application Firewall could be improved by reducing the number of false-negative alerts."
"If they add logs history within the Cloudflare offering, that would be a great benefit."
"Support can be challenging at times."
"Cloudflare Web Application Firewall should include port forwarding features."
"This solution could be improved if the configuration steps were more specific to WAF, compared to other cloud services."
"The solution should identify why it blocks particular websites."
"I would like to see the addition of more advanced rate-limiting features in the next release. It would be beneficial to extend rate limiting beyond just web servers to the main node level."
"The price could be improved."
"For uniformity, AWS has a well-accepted framework. 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."
"The solution could improve by having better rules, they are very basic at the moment."
"I would like to be able to view a graphical deployment map in the user interface that will give me an overview of the configuration and help to determine whether I have missed any steps."
"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 area that should be improved is licensing."
"The area that should be improved is licensing."
 

Pricing and Cost Advice

"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."
"The solution is expensive."
"Cloudflare offers different types of subscriptions for businesses, enterprises, and personal users, and the pricing is negotiable."
"The solution's pricing option needs to be more transparent for enterprise clients."
"Cloudflare Web Application Firewall is more affordable than other solutions."
"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 pricing should be more affordable, especially as it pertains to small clients."
"I would rate AWS WAF's pricing a seven out of ten."
"It has a variable pricing scheme."
"It's cheap."
"You need an additional AWS subscription for this product if you are buying a managed tool."
"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."
"The price is average."
"AWS WAF costs $5 monthly plus $1 for the rule. It's cheap, cost-wise. It's worth the money."
