Room For Improvement

Cloudflare WAF needs feature enhancements, better usability, improved support, advanced DDoS protection, and solutions for latency and alerts.
NetScaler needs improvements in usability, stability, security integration, and support while enhancing documentation, pricing transparency, and deployment processes.
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.
CTO at PlayNirvana
The product can improve by having more multitenancy capability, which is currently not available.
Network Architect at a computer software company with 11-50 employees

All the DNS and everything is routed through Cloudflare, so anybody coming to any of the sites has to go through Cloudflare first, making them the first wall of defense.

We are in the gambling business, in the betting business, so we have constant daily DDoS attacks, and it's always working fine.

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.

Offers better visibility into user sessions compared to other solutions
Improvements are needed to address the issue of machines becoming unregistered, ensuring stability for end users. Troubleshooting with Citrix support can be challenging, so clearer diagnostics would be beneficial. As for global server load balancing, it works well on-premises, depending on user volume and service stability. Overall, it's satisfactory for us.
