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.

Offers Application Protection Against Web Attacks
There is a need for expanded licensing terms and options. There's also a need for improved and more agile customization features. The user needs to be able to manage each policy as required; the functionality needs to empower the user. There should be a complete suite of desktop provider policies available to users. Overall, it needs to be more user-friendly.
