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.

Mutual TLS has secured our web services and now needs broader protocol support

The most valuable feature we have found in Microsoft Azure Application Gateway is mutual TLS. We find mutual TLS valuable because we can verify the client securely by setting up the trust certificate of the client, and also if we do it at the client side as well. This successfully develops mutual trust, ensuring that we know the client who is calling our service is a legitimate client. That is a very nice feature.Microsoft Azure Application Gateway has helped manage our traffic efficiently because we have many web services that we can put behind the same URL, and we can have different URLs with the same Application Gateway with a limited number of listeners. We can do host-based routing as well as URL-based routing or path-based routing. It supports both, so we can have even a single URL supporting many applications, or we can have different URLs for different applications respectively. We have both use cases.

Quotes from Members

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

Pros

"There is a huge signature repository"

"The product has a valuable security control functionality."

"The solution protects our application, which runs on the HTTP protocol, from DDoS attacks."

"It's pretty convenient and pretty easy to set up and run. And then kind of for static content, it also offers caching."

"I'm highly satisfied. It's remarkably user-friendly, enabling me to quickly identify issues, and deploy solutions, and it offers the necessary features."

"Someone with a basic understanding of networking and security will be able to implement the firewall's basic features within 15 minutes."

"It protects web applications efficiently."

"The setup process is very simple for me."

More Cloudflare Web Application Firewall pros

"Our customers are more than satisfied with the user experience provided by the product."

"We chose this solution in the first place because it has access to Layer 7. I can control the requests and the content, which I can access on my network if I want to even if it's forbidden access to other external resources. If I want to monitor, for example, traffic, and apply this rule on Layer 7, I can do so. This was our main goal when implementing this application. We wanted to take advantage of the Gateway capabilities."

"Microsoft Azure Application Gateway impacts our cost savings while maintaining higher performance."

"In my experience, Microsoft products have a smooth integration and facilitate easy management and monitoring. Using Azure Application Gateway allows us to efficiently handle the system loads."

"The solution has built-in rules that reduce alerts and are easy to configure."

"I rate Microsoft Azure Application Gateway's scalability a ten out of ten. My company has more than 1000 users who use it daily."

"The solution's integration is very good."

"Azure Application Gateway's most valuable feature is ease of use. The configuration is straightforward. It isn't difficult to adjust the size of your instances in the settings. You can do that with a few clicks, and the configuration file is the same way. You can also set rules and policies with minimal time and effort."

"The solution's most valuable feature is an HTTP solution and SSL certificate. It is also easy to use."

Cons

"The ModSecurity core rules need to be updated."

"There could be an option to duplicate the cluster to maintain the consistency of rules."

"Its stability could be better."

"We have noticed some latency when the call goes through the firewall. That could be improved."

"They need to improve their support because getting a response for basic requests took around 48 hours, which is too long."

"The user interface is very simple and straightforward, but users need knowledge about DNS to accomplish tasks."

"The solution's learning curve can still be further reduced"

"The accuracy of the Cloudflare Web Application Firewall could be improved by reducing the number of false-negative alerts."

More Cloudflare Web Application Firewall cons

"The tool must be simplified."

"We faced some downtime while validating CNAME."

"The product could be easier to use and implement."

"The increased security that we are considering is because of some of the things that the security team has brought to our attention. They have pointed out that we would most likely require a better web application firewall than Azure Application Gateway."

"Needs easier integration with the existing SIAM."

"Application Gateway’s limitation is that the private and the public endpoint cannot use the same port."

"It could be more stable, and support could be better. It would also be better if they offered more features. For example, it lacks security features. Before we used another English solution, and we realized that some of the rules were not set up correctly and passed through the Application Gateway's English controllers. But the problem, in this case, is if you send ten rules, for example, six rules hit some issues. IP address blocking could be better. The rules, for example, don't work properly. If you have one issue, one rule or another rule will not work. This sounds like total madness to me."

"Application Gateway’s limitation is that the private and the public endpoint cannot use the same port."

"Microsoft needs to work on their documentation."

Pricing and Cost Advice

"The annual licensing fee is $10,000 USD."

"We pay $210 per month for CloudFlare WAF."

"Cloudflare Web Application Firewall is more affordable than other solutions."

"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 solution's pricing option needs to be more transparent for enterprise clients."

"Cloudflare offers different types of subscriptions for businesses, enterprises, and personal users, and the pricing is negotiable."

"It is not too pricey."

"It starts at $20 and can easily go up to $200 monthly"

More Cloudflare Web Application Firewall pricing and cost advice

"The tool is cheap."

"The pricing is based on how much you use the solution."

"Microsoft Azure Application Gateway is a pretty affordable product. My company needs to make yearly payments towards the licensing costs of the solution. The additional costs apart from the licensing costs of the solution vary."

"The solution is reasonably priced."

"The product is expensive. I rate the pricing a seven out of ten."

"I rate the price of Microsoft Azure Application Gateway an eight out of ten."

"The cost is not an issue."

"There is a need to pay a fixed price per month to use the product. There are no additional payments to be made to Microsoft apart from the charges paid towards the monthly licensing costs attached to the solution."

"Microsoft Azure Application Gateway is expensive."
