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 protected our legacy applications effectively but has required constant manual filtering due to false positives
I assess the effectiveness of the machine learning-driven threat detection in Barracuda Web Application Firewall as sometimes behaving abnormally, often showing me false positive attacks, so I have to fix these attacks from time to time. From a stability point of view, I would definitely rate Barracuda Web Application Firewall a seven out of ten. There is definitely some room for improvement; nothing is perfect in the world. I am not satisfied with the technical support from Barracuda. I am somewhat disappointed with the technical support that I have received so far. Whenever I generate a ticket for my problem, it goes to the Indian support team, and they all the time start with the most junior team member, consuming all my precious time. At the end, I have to close that ticket without any satisfactory solution. I have complained that they should shift my support to any other region because I don't need Indian support; they are simply pathetic and not up to mark. To improve Barracuda Web Application Firewall, customers should be given ongoing training opportunities regarding the product and its features. I am not familiar with many features that are available, only using those which are necessary for my applications. I believe Barracuda must provide clearer product information or training sessions to make it more user-friendly, as sometimes its interface can be rigid and lacking in helpful resources or user tutorials about its features. For it to get closer to a ten, I think advanced reporting is missing because, as I mentioned earlier, there are many false positive events being recorded. Often, when I analyze these attacks, they turn out to be genuine customers or users interacting with my product, but Barracuda tags them as attackers. Reducing false positives must be a priority.
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.
