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.

Behavioral analytics and AI automation enhance security and performance
It provides protection for network applications and infrastructure level, and the best part is the behavioral-based detection that Radware provides us, along with real-time signature creation. We also have some applications where we have botnets running, and it provides protection against them. Web DDoS targets the application layer, which is layer seven of the OSI model. For that, we focus on the Web DDoS technique for bot-based attacks because we have many applications where bots are running. We also face many random URL attacks every day, and it protects against malicious or suspicious random URL attacks. It ensures both security and performance. It achieves this by learning behavior patterns and providing protection without blocking normal traffic. These are some of the features I am particularly satisfied with in this product.
