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.

Managed security rules have protected our public e‑commerce sites and simplified ongoing defense
I advise anyone looking for a great tool to secure their public-facing applications to start using F5 Rules for AWS WAF. These are managed rule sets, so you do not need to worry about continuous improvements or ensuring your application is secure; F5 Rules for AWS WAF will take care of that and is always making the necessary improvements in these rule sets to ensure security. I am very impressed with the rule sets and the continuous engineering from their security team to ensure the required rule set availability. I really appreciate the fantastic job they are doing. F5 Rules for AWS WAF can be integrated with AWS CloudFront, Application Load Balancer, Lambda, and API Gateway. I am satisfied with all these services as they are our intermediary points for services exposed to the public or globally. I gave this product a rating of ten out of ten.

Comprehensive web protection has secured public apps and supports advanced audit requirements
Fortinet FortiWeb Cloud WAF-as-a-Service has multiple valuable aspects. The WAF solution secures whatever public domains have been published by the public platform or internal servers exposed to public users. Firewalls have limitations, which is why I suggest using a WAF solution. The firewall provides the same features but in a limited edition. When discussing the SaaS platform or Layer 7 layer of security, you will receive multiple benefits. Firewalls have limitations with signatures, bot protection, and DOS protection. Fortinet FortiWeb Cloud WAF-as-a-Service is a dedicated WAF product that handles all DOS protection, bot protection, API security, endpoint connectivity, signature-based support, and top 10 OWASP support. Multiple features are available. AI and ML-based technology is available in almost every tool today. When discussing troubleshooting, there are AI models that will solve your problem and provide information. AI is helpful because it will give you proper information regarding errors and troubleshooting.
