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

"Very glad the WAF rulesets works out of box, and requires very little tuning or maintenance."
"The security features are valuable. The particular feature we use is called OWASP."
"It is a SaaS solution unlike much of the competition."
"We extensively use the solution every day. The solution is very stable; we haven’t seen any glitches."
"The most valuable part of the solution for us overall is exactly that it is a Software-as-a-Service product."
"We like that there's load balancing, firewall capabilities, DDoS protection, et cetera, all covered by Cloudflare."
"Caching is the most valuable feature of Cloudflare Web Application Firewall."
"I'm highly satisfied. It's remarkably user-friendly, enabling me to quickly identify issues, and deploy solutions, and it offers the necessary features."
"Rule groups are valuable."
"The solution's initial setup process is easy."
"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."
"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."
"It's simple, easy to use."
"The most valuable feature is the capability to limit access based on geographical location by restricting specific IP addresses."
"AWS WAF is a stable solution. The performance of the solution is very good."
"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 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

"Cloudflare Web Application Firewall should include port forwarding features."
"Cloudflare Web Application Firewall should improve visibility for a customer."
"Cloudflare should update the version of the ModSecurity core rule set that they run on."
"The dashboard could be more user-friendly."
"They have some limitations with third-party integrations."
"The accuracy of the Cloudflare Web Application Firewall could be improved by reducing the number of false-negative alerts."
"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."
"Its stability could be better."
"Whenever there is an issue, it is just not that simple to resolve, especially if you don't have premium support."
"The technical support does not respond to bugs in the coding of the product."
"The cost management has room for improvement."
"The product could be improved by expanding the weightage units of rules we have when writing policy."
"The product must provide more features."
"Alternative WAFs have something like bot mitigation or bot control within the WAF, but you don't have such things in AWS WAF."
"On the UI side, I would like it if they could bring back the conditions view which had geo match, IP sets and etc."
"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 area that should be improved is licensing."
 

Pricing and Cost Advice

"Cloudflare Web Application Firewall is more affordable than other solutions."
"Cloudflare offers different types of subscriptions for businesses, enterprises, and personal users, and the pricing is negotiable."
"The solution is expensive."
"The annual licensing fee is $10,000 USD."
"The solution's pricing option needs to be more transparent for enterprise clients."
"We pay $210 per month for CloudFlare WAF."
"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 starts at $20 and can easily go up to $200 monthly"
"The product’s pricing is reasonable."
"There are no separate licensing costs we pay for since it is included in the plan we purchase."
"I would rate AWS WAF's pricing a seven out of ten."
"The price of AWS WAF is expensive if you do not know how to manage your software up or down. I price of the solution is average amongst the other competitors but it would be better if it was less expensive."
"AWS is not that costly by comparison. They are maybe close to $40 per month. I think it was between $29 or $39."
"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."
"It's an annual subscription."
"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."
