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 significantly improved threat visibility and reduced false positives through intelligent bot detection and real-time analysis
The best features of Radware Cloud WAF Service that I prefer most include the bot protection. Its deployment was very smooth and flexible when I started deploying it. The reporting and visibility feature of the Bot Manager are noteworthy, as the dashboard gives clear insight into the traffic, activity, and block threats. The AI threat intelligence feature is quite impressive. In terms of blocking unknown threats and attacks, I assess Radware Cloud WAF Service as quite impressive; if I have to rate it out of 10, I would rate it eight and a half. The automated analytics for looking at events with Radware Cloud WAF Service is generally fine, and whenever we use it, it gives almost perfect results. In API protection with Radware Cloud WAF Service, we have multiple applications that we are using currently, and whenever there is any threat related to an API, it helps us provide detailed insight. Additionally, whenever there is unusual API traffic, it helps us monitor and detect threats.

Room for improvement with user interface while competitive pricing impresses
It is managed through Infrastructure as Code, so all configurations can be managed in the code itself, which is beneficial. Because it uses rules, it is easy to set up, and we have many different sites where the configurations are straightforward. Though the UI is not very interactive, which is a downside, we can manage many things. The UI is not very intuitive and could be better. However, we manage all the configurations through code, which is easy to maintain. It has extensive anomaly detection capabilities, so the traffic is classified into several categories where thresholds can be defined and customized based on false positives and false negatives. This is advantageous because you do not need to tweak it very often. Once you set it up, an audit once a quarter would suffice. Because The Fastly Next-Gen WAF (powered by Signal Sciences) is API-driven, we have integrations with the CI/CD pipeline through GitHub Actions, making it easy to integrate.

Pros

"The product's most valuable feature is its ability to set up the rules easily."
 

Cons

"The ModSecurity core rules need to be updated."
"I have experienced some difficulties with Cloudflare's support as a customer based in India."
"It would be ideal if the solution offered better log integration and more integration with different platforms."
"The reporting could be improved if it were more granular."
"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 accuracy of the Cloudflare Web Application Firewall could be improved by reducing the number of false-negative alerts."
"The rate limiting functionality could be enhanced, as we find it somewhat limited."

"Radware needs to improve the certificate renewal process for customers who want to be secured with HTTPS."

"It would be ideal if Radware could offer a bundled package that includes Cloud WAF, web DDoS protection, bot manager, and Alteon for a more comprehensive security solution."
"Radware Cloud WAF Service could improve by having greater availability in Spanish for support, as generally there are English-speaking engineers, which may be a challenge for some people."
"Even if we create some custom rules, Signal Sciences cannot capture some of the malicious traffic."
"The UI is not very intuitive and could be better."
"Fastly don't support caching for China users. That's the only feature lacking compared to Akamai."
"The areas that could be improved in Signal Sciences include the effectiveness of rules, as many didn't function optimally and required custom rule-writing to address bypasses for WAF."
