Even if an attacker detects the IP address, they can't connect directly to the server due to FortiWeb
The xFF, or X-Forwarded-For feature, IP reputation, and protected hostname. We can block access using the IP address, so no one can connect to our web server or website using the real IP. They need to use the FQDN instead. Even if an attacker detects the IP address, they can't connect directly to the server due to FortiWeb and the option to protect the hostname. All traffic passes through FortiWeb. Machine learning capabilities in FortiWeb: I don't use machine learning all the time. In the initial phase of FortiWeb deployment, we use the learning process to detect the traffic passing through FortiGate to our website.

Provide DDoS protection and better security at effective rate
It is expanding its number of data centers for scrubbing traffic. Currently, there is only one POP for cleaning in South Africa. They might add another POP in North Africa, possibly in Nigeria or Egypt. Latency concerns customers, especially in regions like East and West Africa, where traffic has to travel to South Africa before returning. Increasing the number of POPs across the continent would help address these latency issues and improve overall service. While the platform is already quite strong, there’s always room for improvement, especially in keeping up with emerging trends and new types of attacks. Enhancing security capabilities could be beneficial. Integrating more advanced AI features could significantly improve its effectiveness and help customers leverage these tools more effectively. It would be great to see more focus on AI integration to handle and analyze data more efficiently.
