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.

Long-term web protection has supported reliable traffic management but needs a simpler interface

NGINX App Protect is a good product. I have used both versions from F5 -also the free version- (I mean the NGINX/NGINX One/App Protect free trial period), and I think it is a good product. It's stable, affordable, and easy to manage. NGINX App Protect is a comprehensive security solution that combines advanced WAF, DoS protection, API security, and DevSecOps automation in a lightweight, scalable package ideal for modern cloud-native architectures. The adaptive machine learning capabilities are truly commendable, as the solution can establish traffic baselines and detect anomalies in real time. It automatically adjusts security policies, minimizing the need for manual intervention and reducing false positives. Additionally, it supports scalable deployment across diverse environments, including on-premises, cloud, Kubernetes, and containers, offering both flexibility and scalability I have experience with the web server, F5 load balancer, and similar products provided by Ergon, for eg. the web application firewall and the Microgateway for K8S. I'm also familiar with F5 BIG-IP products.

More NGINX App Protect pros

Cons

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

"The blocked logs are difficult to read at times."

"It would be ideal if the solution offered better log integration and more integration with different platforms."

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

"Its stability could be better."

"The product can improve by having more multitenancy capability, which is currently not available."

More Cloudflare Web Application Firewall cons

"The tool must be simplified."

"Areas for improvement would be if NGINX could scan for vulnerabilities and learn and update the signatures of DoS attacks."

"NGINX App Protect would be improved with integration with Shape and F5 WAF, which would make it easy for users to manage all their web application security with a single solution."

"They could provide a better user interface."

"NGINX App Protect could improve security."

"The solution does well when there's low throughput but when we go for any high throughput, it's always a challenge."

"Setting policies and parameters through the UI should be more automated because the process is manual, where we can only edit one rule at a time."

"It's challenging if you need to go for a high throughput."

"NGINX's technical support is good, but sometimes their response time is delayed, or they don't have the technical skills to resolve issues."
