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.

Granular security policies have protected critical applications and ensure safe user and admin access
Improvements could be made regarding the log information from the backend CLI. There are enhancements needed; if a request gets blocked on the TCP layer, there should be traces or data to verify which source generated these requests, including the source and port information for initiation. These data are missing from F5 Advanced WAF. Besides that, another improvement could be refining the bot detection to minimize false positives; it should be able to verify more granularly between legitimate and non-legitimate clients. Overall, I find everything else good. A wish list feature I have is for the Technical Assistance Center (TAC) to respond more promptly. Their response time needs improvement; while they do not take excessive time, it can be enhanced, especially given it is a security product.

Offers Application Protection Against Web Attacks
There is a need for expanded licensing terms and options. There's also a need for improved and more agile customization features. The user needs to be able to manage each policy as required; the functionality needs to empower the user. There should be a complete suite of desktop provider policies available to users. Overall, it needs to be more user-friendly.

"The support experience is better than average."

"I have experienced some difficulties with Cloudflare's support as a customer based in India."

"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 can improve by having more multitenancy capability, which is currently not available."
"The blocked logs are difficult to read at times."
"They have some limitations with third-party integrations."
"Cloudflare Web Application Firewall should include port forwarding features."
"It's a powerful tool yet can be complex for new users."
"I think the price is very high. This is what I hear from the customers."
"There is a learning curve that extends the time of implementation."
"I think the solution is already being phased out."
"The product could be more user-friendly for administrators."
"They should work on the virtualization of NGINX."
"What needs to be improved in this solution is the accuracy of its automatic learning feature, because we frequently have to help it manually, particularly to stop blocking things it isn't supposed to block."

Pricing and Cost Advice

"Cloudflare Web Application Firewall is more affordable than other solutions."
"It starts at $20 and can easily go up to $200 monthly"
"The annual licensing fee is $10,000 USD."
"It is not too pricey."
"The solution's pricing option needs to be more transparent for enterprise clients."
"We pay $210 per month for CloudFlare WAF."
"Cloudflare offers different types of subscriptions for businesses, enterprises, and personal users, and the pricing is negotiable."
"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."
"After buying the program, you just pay for the support every year."
"There are various plans available for Fortinet FortiWeb Cloud WAF as a Service, including a trial version."
"Licensing fees for this solution are paid on a yearly basis."
"Pricing for this solution is higher than average."
"It is a little bit costly, but it has all the features that are required."
"There is an annual subscription for this solution."
"Its price is fair. We have done a couple of deals where they were able to give some kind of discount to the customers. The price was initially high for the customers, but after a couple of negotiations, it came within their budget. They were happy with that."
"The solution is very expensive so should only be used in the right environment."
