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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"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."
"It is configurable via API."
"The security features are valuable. The particular feature we use is called OWASP."
"The solution protects our application, which runs on the HTTP protocol, from DDoS attacks."
"It is a SaaS solution unlike much of the competition."
"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."
"Some of the most valuable features of Cloudflare Web Application Firewall include its DNS zone setup and the zero trust policy."
"I can recommend F5 Advanced WAF to any customer because we have experience, and referrals from customers using it within different models."
"The most valuable feature is artificial intelligence and to get extra internal access."
"F5 technical support is excellent. They are experts who always provide the right solution, and they understand the problem. Their response and resolution times are good."
"I appreciate the way F5 Advanced WAF builds policies by configuring a basic policy and queuing it in learning mode."
"The web application firewall itself is most valuable. It provides positive security and negative security. In negative security, it blocks a task such as cross-site scripting, code injection, etc. In positive security, it lets you specify and enforce things, such as the parameters allowed in username and password fields and the number of characters allowed in a field."
"F5 Advanced WAF is a comprehensive community platform with a strong commitment, making it valuable for businesses."
"It's a fairly easy-to-use and user-friendly tool. My administrators and team also like its ability to customize the rules per the requirements."
"The product has valuable features for load balancing, monitoring tools, and HPXpress services."
"Since we are using this tool for protection purposes we really appreciate the hybrid security abilities; the main idea here is that we powerful protection our application needs."
 

Cons

"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."
"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 solution's learning curve can still be further reduced"
"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."
"Cloudflare Web Application Firewall should include port forwarding features."
"The user interface is very simple and straightforward, but users need knowledge about DNS to accomplish tasks."
"Nevertheless, F5 products are generally considered to be hard to deploy."
"Improvements could be made regarding the log information from the backend CLI; 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."
"F5 Advanced WAF sells perpetual licenses as perpetual assets during sales without informing me that support ends after a few years."
"Although we're getting some reports, we're not getting all the reports we need. There seems to be a gap in report management."
"Truthfully, they can improve a bit. Sometimes you get an engineer who is absent for two, three days and you have to call them and change engineers because the first one is not responding."
"The solution should include RASP for another level of protection at the code itself."
"There should be more ability to rate limit certain scenarios."
"The BNS module needs improvement."
"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

"Cloudflare Web Application Firewall is more affordable than other solutions."
"The annual licensing fee is $10,000 USD."
"The solution's pricing option needs to be more transparent for enterprise clients."
"The solution is expensive."
"It is not too pricey."
"It starts at $20 and can easily go up to $200 monthly"
"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."
"We pay $210 per month for CloudFlare WAF."
"After buying the program, you just pay for the support every year."
"F5 bundles up services and the bundle is what you pay for rather than individual components."
"The price of the solution is reasonable when compared with other products, such as FortiWeb. I am very satisfied with the price."
"The pricing of F5 Advanced WAF is more expensive than other solutions like Radware and CD18, it is quite high."
"There are various plans available for Fortinet FortiWeb Cloud WAF as a Service, including a trial version."
"F5 Advanced WAF is not a cost-effective solution. Although they are attempting to reduce prices with their VE and cloud options, they are more expensive than other solutions. The solution is more expensive on average."
"As far as the pricing of F5 Advanced WAF I would rate it a four out of five depending on what features I am looking for. Imperva is more expensive."
"The pricing for F5 Advanced WAF is comparable to a Rolls-Royce. Its price is a bit high when you compare it with other vendors. F5 Advanced WAF is a bit expensive. The customer was on a three-year plan and it was around $560,000."
