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.

Has successfully filtered malicious traffic and allowed country-specific access controls
For improvement in AWS WAF, we can have better monitoring. One of the things that should be improved in AWS WAF is the monitoring; we need to identify the requests and where they are coming from. If it's a bot, we should differentiate the requests, whether they are automated or not. The way we see it now is just mentioned as a percentage from bots and actual users, which should include proper graphs and detailed information. We also need a feature where we can filter specific requests. If there are scripts in the requests, we should be able to filter those requests to see if there are any scripts running from them.
Mohan Janarthanan - PeerSpot reviewer

Cloud applications have gained stronger protection and real-time defense against web attacks
What really stands out for me in terms of advantages of F5 Silverline Managed Services is that in a single cloud platform, I can protect my web applications against attacks. I can also use my load balancer in F5 because they are providing and acting as a load balancer too, and they will support the volumetric and DDoS attacks and malicious attacks. Regarding the real-time threat intelligence feature, I do use this aspect in F5 Silverline Managed Services. It blocks malicious IPs or bad IPs for my server, protecting against my applications. For example, if someone is a bad actor trying to access via a malicious IP, I can block it because the threat intelligence has the capability to block the malicious IP. The adaptable and flexible security impacts threat response time positively. It is effective because it blocks my malicious traffic. Whenever I face issues related to that application, it automatically routes my traffic to act as a proxy and routes my traffic to their scrubbing center, especially in case of any volumetric attack.
