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.

Cons

"The accuracy of the Cloudflare Web Application Firewall could be improved by reducing the number of false-negative alerts."
"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."
"The user interface is very simple and straightforward, but users need knowledge about DNS to accomplish tasks."
"The reporting could be more granular."
"The reporting could be improved if it were more granular."

"We usually use a third-party tool for logging and reporting. It would be nice if we could do that right on this solution."
"The BIG-IQ is supposed to centralize the management for all of the boxes but it's not very effective."
"There is a learning curve that extends the time of implementation."
"The reporting portion of F5 Advance WAF is not great. They need to work out something better, as it is very basic."
"It's a powerful tool yet can be complex for new users."
"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."
"There is a need for expanded licensing terms and options. There's also a need for improved and more agile customization features."
 

Pricing and Cost Advice

"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."
"It is not too pricey."
"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."
"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"
"The solution's pricing option needs to be more transparent for enterprise clients."
"It's more expensive than other solutions and depending on the modules, there can be additional fees."
"I am not sure about pricing but licenses are available on Google."
"I don't have any issue with the pricing of this solution."
"The pricing of F5 Advanced WAF is more expensive than other solutions like Radware and CD18, it is quite high."
"The way we deployed it, I would rate it a four out of five in terms of pricing."
"A yearly license for F5 Advanced WAF is expensive."
"I would rate the pricing as seven out of ten"
"I think the price is very high."
