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 impact of Cloudflare Web Application Firewall's integration with existing web technologies on our site's performance and security measures is quite great, actually."
"We like that there's load balancing, firewall capabilities, DDoS protection, et cetera, all covered by Cloudflare."
"The initial setup process is simple."
"The solution protects our application, which runs on the HTTP protocol, from DDoS attacks."
"Caching is the most valuable feature of Cloudflare Web Application Firewall."
"Cloudflare WAF provides protection through rules and functionalities like Cloudflare's SDRAP."
"Someone with a basic understanding of networking and security will be able to implement the firewall's basic features within 15 minutes."
"Technical support has a very fast response time and they are helpful."
"The most valuable feature of AWS WAF is the extra layer of security that I have when connecting to my web applications."
"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."
"It is Amazon. Everything is scalable. It is beyond what we need."
"The most valuable feature of the solution is the ability to integrate central sets. It protects from intrusion attacks such as scripting and SQL injections."
"What I like best about AWS WAF is that it's a simple tool, so I could understand the basics of AWS WAF in two to three hours."
"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 has helped to strengthen the security of my environment; it has also helped to improve the posture of our application, prevent all DDoS attacks and unnecessary traffic and SQL injection that is reducing the performance of our application."
"We can host any DB or application on the solution."
"The three most valuable features that I noticed are the geo-localization of the user, the IP reputation, and the compartmental analysis."
 

Cons

"I have experienced some difficulties with Cloudflare's support as a customer based in India."
"The product can improve by having more multitenancy capability, which is currently not available."
"The blocked logs are difficult to read at times."
"Cloudflare Web Application Firewall should improve visibility for a customer."
"The learning curve was steep initially."
"Cloudflare Web Application Firewall should include port forwarding features."
"Its stability could be better."
"If they add logs history within the Cloudflare offering, that would be a great benefit."
"I find the documentation somewhat complex to implement during the initial stages."
"When users choose the free service, there isn't great support available to them."
"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."
"The solution could be more reliable."
"The solution is cloud-based, and therefore the billing model that comes with it could be more intuitive, in my opinion. It's very easy to not fully understand how you tag things for billing and then you can quite easily run up a high bill without realizing it. The solution needs to be more intuitive around the tagging system, which enables the billing. Right now, I have a cloud architect that does that on our behalf and it isn't something that a business user could use because it still requires quite a lot of technical knowledge to do effectively."
"We haven't faced any problems with the solution."
"AWS WAF's signature sets have room for improvement due to false positives."
"They should make the implementation process faster."
"The area that should be improved is licensing."
 

Pricing and Cost Advice

"The pricing model is very straightforward compared to the competition. You just pay per month for the product and usage."
"It starts at $20 and can easily go up to $200 monthly"
"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 expensive."
"Cloudflare offers different types of subscriptions for businesses, enterprises, and personal users, and the pricing is negotiable."
"It is not too pricey."
"We pay $210 per month for CloudFlare WAF."
"Cloudflare Web Application Firewall is more affordable than other solutions."
"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."
"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 WAF costs $5 monthly plus $1 for the rule. It's cheap, cost-wise. It's worth the money."
"There are no costs in addition to the standard licensing fees."
"The product’s pricing is reasonable."
"The solution's cost depends on the use cases."
"There are different scale options available for WAF."
"It's cheap."
