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.

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.

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.

To prevent OWASP TOP 10 (SQL Injection, XSS, XSFR...etc) attacks, stop L7 DDoS like SlowLoris and HeavyURL, protect against web fraud, phishing and endpoint malware (Dridex) on endpoint machines outside administrative control, secure application API's, the option to deploy as a managed service in the cloud and available on premises, use DAST integration for policy building with Qualys, Cenzic, ...

Today i would say Barracuda is the better WAF based on that Imperva Dev slowed down over the last two years and the customers give bad feedback on the support, but there is a newer generation of WAF´s in the market that is better than Imperva and Barracuda, both in performance and price, PT application firewall, the only visionary in the GMQ
