Radware Cloud WAF Service faces integration, support, and UI issues; improvements in language support and API management are needed.

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.

SOC Analyst at Adani Enterprises Ltd
Has significantly improved threat visibility and reduced false positives through intelligent bot detection and real-time analysis
The best features of Radware Cloud WAF Service that I prefer most include the bot protection. Its deployment was very smooth and flexible when I started deploying it. The reporting and visibility feature of the Bot Manager are noteworthy, as the dashboard gives clear insight into the traffic, activity, and block threats. The AI threat intelligence feature is quite impressive. In terms of blocking unknown threats and attacks, I assess Radware Cloud WAF Service as quite impressive; if I have to rate it out of 10, I would rate it eight and a half. The automated analytics for looking at events with Radware Cloud WAF Service is generally fine, and whenever we use it, it gives almost perfect results. In API protection with Radware Cloud WAF Service, we have multiple applications that we are using currently, and whenever there is any threat related to an API, it helps us provide detailed insight. Additionally, whenever there is unusual API traffic, it helps us monitor and detect threats.
