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.

Has successfully filtered malicious traffic and allowed country-specific access controls
For improvement in AWS WAF, we can have better monitoring. One of the things that should be improved in AWS WAF is the monitoring; we need to identify the requests and where they are coming from. If it's a bot, we should differentiate the requests, whether they are automated or not. The way we see it now is just mentioned as a percentage from bots and actual users, which should include proper graphs and detailed information. We also need a feature where we can filter specific requests. If there are scripts in the requests, we should be able to filter those requests to see if there are any scripts running from them.

Edge caching has transformed response times and delivers faster candidate data globally
Fastly can be improved in certain areas such as VCL, which is powerful but has a steep learning curve for normal users. A more user-friendly, UI-based configuration could simplify the experience, alongside better templates for common use cases and dashboard improvements, as the current dashboard feels complex for beginners, and pricing can be hard to predict for smaller companies. I chose 8 out of 10 because it has excellent performance and low latency delivery, making it suitable for larger applications, with strong Edge Caching and instant purging capabilities. However, VCL complexity and pricing predictability, especially for smaller companies, along with a user-friendly dashboard are areas impacting my score.

Quotes from Members

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

Pros

"It protects web applications efficiently."
"Cloudflare is cheaper compared to Azure WAF, which I have considered before."
"Someone with a basic understanding of networking and security will be able to implement the firewall's basic features within 15 minutes."
"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."
"For us, the key feature of Cloudflare is DDoS protection and IP hiding, especially since we are a crypto company."
"Cloudflare WAF provides protection through rules and functionalities like Cloudflare's SDRAP."
"The rate limiting features and customizations in terms of URL match and applying policies are valuable to me."
"The stability of Cloudflare Web Application Firewall deserves a perfect 10 out of 10."
"AWS WAF has a lot of integrated features and services, for example, there are security services that can be integrated very well for our customers."
"Its best feature is that it is on the cloud and does not require local hardware resources."
"The features I find most useful in AWS WAF are that we can integrate and write custom regex rules where we can specify URLs or links that cannot be accessed by certain countries or specific IPs."
"The most valuable feature is the addition of managed tools that help us create customizable rules. In case we want to block a particular request, we can make use of those rules."
"If hackers try to insert bugs, the tool blocks it."
"The product’s availability, ease of configuration, and documentation are valuable."
"I believe the most impressive features are integration and ease of use, and the best part of AWS WAF is the cloud-native WAF integration, where AWS maintains everything and all we have to do is click the button and WAF will be activated so any packet coming through the internet will be filtered through."
"This product supplies options for web security for applications accessing sensitive information."
"Rate limiting is a good feature that protects from volumetric attacks."
"The product helps our organization to access sites located in different regions quickly."
"Its initial setup process is straightforward."
"Support is good; the product works as advertised. We have a Slack connection with them. So we can basically ask for help, live, engage, and ring when they respond. Very quickly."
"Compute@Edge features are valuable to me."
"Fastly provides CDN, WAF, image optimization, and IP restriction."
"Fastly combines both the CDN side and the Signal Sciences next-generation WAF, which is closely integrated with the CDN, allowing us to use both products seamlessly."
"Fastly uses configuration versioning, where you can deploy a new version in less than one minute."
 

Cons

"The reporting could be improved if it were more granular."
"It would be ideal if the solution offered better log integration and more integration with different platforms."
"The platform's control features related to real-time authentication and response time need improvement."
"They have some limitations with third-party integrations."
"There could be an option to duplicate the cluster to maintain the consistency of rules."
"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."
"We have noticed some latency when the call goes through the firewall. That could be improved."
"The product can improve by having more multitenancy capability, which is currently not available."
"AWS WAF's signature sets have room for improvement due to false positives."
"This solution could be improved if the configuration steps were more specific to WAF, compared to other cloud services."
"The user experience, the interface, is lacking. Sometimes it's hard to find certain areas that it has alerted on."
"We need more support as we go global."
"AWS WAF should provide better protection to its users, and the security features need to improve."
"The solution could improve by having better rules, they are very basic at the moment. There are more attacks coming and we have to use third-party solutions, such as FIA. The features are not sufficient to prevent all the attacks, such as DDoS. Overall the solution should be more secure."
"I would like to be able to view a graphical deployment map in the user interface that will give me an overview of the configuration and help to determine whether I have missed any steps."
"I would like to see the addition of more advanced rate-limiting features in the next release. It would be beneficial to extend rate limiting beyond just web servers to the main node level."
"It is missing a "staging" platform to deploy a test configuration with all of the real settings, which would allow us to properly test before putting it into production."
"Stronger analytics would be helpful, like showing configurations that haven't served a certain amount of traffic in a while. With many properties, things can get lost track of - duplicates or unused configurations not properly decommissioned."
"Fastly's customer service area needs improvement."
"Fastly can be improved in certain areas such as VCL, which is powerful but has a steep learning curve for normal users."
"The solution's pricing could be better."
"We are not getting quick responses from Fastly technical support engineers. Sometimes they depend on their D3 developers."
"Support is not that great."
"It's not easy to start with Fastly if you don't have VCL knowledge, so it appears very complex at the beginning."
