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 integration of Cloudflare with Cloud Suite is its most valuable feature."
"Some of the most valuable features of Cloudflare Web Application Firewall include its DNS zone setup and the zero trust policy."
"This is a good product; it's reliable and scales well."
"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."
"For us, the key feature of Cloudflare is DDoS protection and IP hiding, especially since we are a crypto company."
"Cloudflare has positively impacted my organization by making it easier for me to handle and set up DNS for multiple clients; I can easily go in and access their accounts, make changes they need, and it's a one-stop shop."
"The Cloudflare Web Application Firewall's most valuable feature is its ease of configuration."
"The initial setup process is simple."
"The customized billing is the most valuable feature."
"It is Amazon; everything is scalable, and it is beyond what we need."
"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 interface is good."
"Its best feature is that it is on the cloud and does not require local hardware resources."
"It is a one-click WAF with no effort needed."
"The ability to take multiple data sets and match those data sets together is the solution's most valuable feature."
"It is Amazon. Everything is scalable. It is beyond what we need."
"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

"The reporting could be improved if it were more granular."
"If they add logs history within the Cloudflare offering, that would be a great benefit."
"Their documentation could be better. They don't have documentation that explains everything well."
"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."
"The blocked logs are difficult to read at times."
"Its stability could be better."
"The ModSecurity core rules need to be updated."
"We don't even use Cloudflare Bot Management because it's too expensive; you need to pay per request, and it's much cheaper to get one or two additional machines."
"The product must provide more features."
"The issue with AWS WAF is that the rule structure is very complicated and it is very hard to maintain."
"It would be better if AWS WAF were more flexible. For example, if you take a third-party WAF like Imperva, they maintain the rule set, and these rule sets are constantly updated. They push security insights or new rules into the firewall. However, when it comes to AWS, it has a standard set of rules, and only those sets of rules in the application firewalls trigger alerts, block, and manage traffic. Alternative WAFs have something like bot mitigation or bot control within the WAF, but you don't have such things in AWS WAF. I will say there could have been better bot mitigation plans, there could have been better dealer mitigation plans, and there could be better-updated rule sets for every security issue which arises in web applications. In the next release, I would like to see if AWS WAF could take on DDoS protection within itself rather than being in a stand-alone solution like AWS Shield. I would also like a solution like a bot mitigation."
"While the complexity of the installation can vary from one service to another, overall, I would say that it and the configuration and navigation are somewhat complex."
"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."
"The price could be improved."
"The solution's pricing could be improved."
"We should be able to do proper whitelisting."
"The area that should be improved is licensing."
"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."
"It starts at $20 and can easily go up to $200 monthly"
"Cloudflare Web Application Firewall is more affordable than other solutions."
"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."
"The solution is expensive."
"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 annual licensing fee is $10,000 USD."
"The price is average."
"There are no separate licensing costs we pay for since it is included in the plan we purchase."
"I rate the product price a five on a scale of one to ten, where one is high price, and ten is low price"
"I would rate AWS WAF's pricing a seven out of ten."
"It's quite affordable. It's in the middle."
"AWS is not that costly by comparison. They are maybe close to $40 per month. I think it was between $29 or $39."
"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."
"AWS WAF costs $5 monthly plus $1 for the rule. It's cheap, cost-wise. It's worth the money."
