CTO at PlayNirvana
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.
Owner at Hga consulting
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
Maybe Imperva DDoS could use endpoints to get information about the attacks before they commence from the endpoint level or establish cooperation with endpoint vendors to share this information.

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.

Solution ensures website availability and proactive threat mitigation
Over the seven years, the most valuable features of Imperva DDoS that I have found are related to DDoS attacks, which are a group of attacks, and not all of them can be resolved on the endpoint level before the website. Using the web firewall before the website is a common use case to protect against malicious requests to the website. I have utilized Imperva's Intelligent Traffic Filtering feature. This feature helps me understand how the attack is progressing and what is happening inside the requests to our website. It allows me to granularly grant or deny access to certain parts of our website. This helps when we know our customers and the types of requests that can be sent from them, enabling us to block some malicious requests. Imperva DDoS has User Behavior Analytics and Threat Intelligence on its board, and this helps us to be protected proactively. Imperva DDoS connects to its database of threats, storing whole information about attacks all over the world in one simple engine. Everyone can use this feature, which can connect to this engine and get information about what is going on at the world level. That is the way to be protected at the company's level. The integration capabilities of Imperva DDoS are very easy and simple. We can run it in 2 hours.
