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.

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

"It is a SaaS solution unlike much of the competition."
"The product has improved our security posture by blocking bad actors."
"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 initial setup process is simple."
"The impact of Cloudflare Web Application Firewall's integration with existing web technologies on our site's performance and security measures is quite great, actually."
"There is a huge signature repository"
"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."
"The security features are valuable. The particular feature we use is called OWASP."
"One of the most valuable features is the Local Traffic Manager."
"The valuable features vary from customers to customers. Some customers are okay with the basic features of the WAF, and some customers use advanced WAF with a few other features."
"Despite a few issues, F5 Advanced WAF is performing well for me."
"iRules are quite appealing when it comes to F5."
"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."
"Very easy to implement and works well."
"There are more features than any other product I can think of."
"As far as I am concerned, F5 Advanced WAF is one of the most stable solutions I've ever used, so it's good to implement."
"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

"The solution's learning curve can still be further reduced"
"Support can be challenging at times."
"WAF doesn't directly affect bandwidth costs. It saves costs on protection. However, with the correct setup, it's difficult to determine if it saves costs overall due to the fixed enterprise plan fee."
"I have experienced some difficulties with Cloudflare's support as a customer based in India."
"Their documentation could be better. They don't have documentation that explains everything well."
"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."
"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 ModSecurity core rules need to be updated."
"I think the deployment templates can be better."
"We usually use a third-party tool for logging and reporting. It would be nice if we could do that right on this solution. They have one, but it's not very stable. Logging and reporting effectively would be a big enhancement."
"While F5 Advanced WAF does limit the number of partners in certain regions to ensure successful business transactions, they could also benefit from expanding their partnerships and making it easier for more people to learn about and become experts in F5 Advanced WAF. By doing so, they could increase the reach and exposure of their solution, similar to how Cisco has become widely recognized in the security industry."
"The delay times on firmware patches and software updates could be better and improved."
"The user interface (UI) seems a bit outdated. Making it more user-friendly would be beneficial."
"Everything is good about the F5 WAF, except the reporting. It's really difficult to set records from that device, the UI is kind of hard to work with, and the reporting must be improved."
"Support is a little slow."
"I think the solution is already being phased out."
"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."
"Cloudflare offers different types of subscriptions for businesses, enterprises, and personal users, and the pricing is negotiable."
"We pay $210 per month for CloudFlare WAF."
"It is not too pricey."
"Cloudflare Web Application Firewall is more affordable than other solutions."
"The solution is expensive."
"It starts at $20 and can easily go up to $200 monthly"
"The annual licensing fee is $10,000 USD."
"Pricing for this solution is higher than average."
"It's more expensive than other solutions and depending on the modules, there can be additional fees."
"I think the price is very high."
"I am not sure about pricing but licenses are available on Google."
"The pricing is too high."
"It is a little bit costly, but it has all the features that are required."
"After buying the program, you just pay for the support every year."
"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."
