I think they're doing a good job with DNS and as support for any domains that I create or that my clients create, it's mandatory for me to ensure they have Cloudflare as their DNS provider.

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.
CTO at PlayNirvana
To stay safer from a security perspective, continuous improvisation in these security rules is required to ensure we are always up to date with new attacks.
Associate Vice President at Hitachi Systems India Private Limited
Fine-tuning it to match specific application behavior can sometimes be complex and time-consuming, especially for teams without deep WAF expertise.

CTO at PlayNirvana
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.

Advanced protection has reduced web attacks and improves application performance and operations
One area where F5 Rules for AWS WAF can be improved is in simplifying the tuning process. While F5 Rules for AWS WAF is powerful, fine-tuning it to match specific application behavior can sometimes be complex and time-consuming, especially for teams without deep WAF expertise. Another improvement could be enhanced visibility and reporting. Although AWS WAF provides logs, having more intuitive and built-in dashboards or clearer categorization of rule triggers would make it easier to quickly identify and analyze attack patterns. Additionally, expanding the capabilities around bot management and behavior analysis would be beneficial compared to some dedicated bot management solutions. More advanced detection techniques could further strengthen the protection against sophisticated automated traffic. Finally, providing more predefined templates or best practice recommendations for different application types would help speed up the deployment and reduce the initial configuration effort.

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.
