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

"Someone with a basic understanding of networking and security will be able to implement the firewall's basic features within 15 minutes."
"The setup process is very simple for me."
"Some of the most valuable features of Cloudflare Web Application Firewall include its DNS zone setup and the zero trust policy."
"The integration of Cloudflare with Cloud Suite is its most valuable feature."
"There is a huge signature repository"
"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 most valuable part of the solution for us overall is exactly that it is a Software-as-a-Service product."
"It protects web applications efficiently."
"The automation of blocking for security attacks is valuable, with AWS applying rate limiting."
"The product’s availability, ease of configuration, and documentation are valuable."
"AWS WAF is a stable solution. The performance of the solution is very good."
"The solution's initial setup process is easy."
"AWS is very user-friendly and largely inexpensive, however, if an organization has the budget, there are lots of great products out there that do largely the same thing."
"The web solution effectively protects from vulnerabilities and cyber attacks."
"The most valuable feature of AWS WAF is the extra layer of security that I have when connecting to my web applications."
"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."
"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

"Support can be challenging at times."
"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."
"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."
"WAF doesn't directly affect bandwidth costs. It saves costs on protection. However, with the correct setup, it's difficult to determine if it saves costs overall due to the fixed enterprise plan fee."
"They have some limitations with third-party integrations."
"The notification part could be improved. It's very much connected to Web Application Firewall, rate-limiting, and DDoS protection."
"Cloudflare should update the version of the ModSecurity core rule set that they run on."
"I have experienced some difficulties with Cloudflare's support as a customer based in India."
"It's a bit difficult to apply the right rules for the right security."
"The default content policy available in the tool is not very strong compared to the competitors."
"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."
"We don't have much control over blocking, because the WAF is managed by AWS."
"The price could be improved."
"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."
"An improvement area would be that it's more of a manual effort when you have to enable rules. That's one of the downsides. If that can be done in an automated way, it would be great. That's a lagging feature currently."
"I would like to see it more tightly integrated with other AWS services."
"The area that should be improved is licensing."
 

Pricing and Cost Advice

"The solution's pricing option needs to be more transparent for enterprise clients."
"The solution is expensive."
"Cloudflare Web Application Firewall is more affordable than other solutions."
"It is not too pricey."
"We pay $210 per month for CloudFlare WAF."
"The annual licensing fee is $10,000 USD."
"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 pricing model is very straightforward compared to the competition. You just pay per month for the product and usage."
"I would rate AWS WAF's pricing a seven out of ten."
"The pricing is good and manageable."
"The product’s pricing is reasonable."
"I rate the product price a five on a scale of one to ten, where one is high price, and ten is low price"
"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."
"The price is average."
"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."
