IshtiaqKhalil - PeerSpot reviewer
Information Security Engineer at BOK
Displays flexible, user-friendly interface with minor licensing challenges
The product could be improved with a more intuitive interface for complex configurations and more advanced analytics. Additionally, enhanced security features, like a more robust Web Application Firewall, and stronger APIs for better automation would be beneficial. Overall, the main areas for improvement are in strengthening the advanced features to better meet the demands of large-scale enterprise environments. key features for the next release should focus on three areas. First, an enhanced, next-generation security suite with a more powerful Web Application Firewall (WAF) and integrated bot protection. Second, more advanced and customizable analytics dashboards to provide deeper insights into application performance. Finally, greater support for modern, cloud-native environments, including better APIs for automation and seamless hybrid-cloud traffic management

Advanced protection has optimized web and API performance while reducing infrastructure costs
From the features perspective and functionality-wise, there are areas of Radware DDoS that I would like to see improved or enhanced in the future. Version upgrades are being provided, but they should communicate with clients about these new features being available so clients can test them and deploy them on the disaster recovery system before moving to the live segment. There should be a test report that will provide confidence that the version is stable and everything will work properly. Last time we faced an issue with a version upgrade, and we faced extensive troubleshooting with littile bit more time in the troubleshooting process. It turned out to be a small issue that was resolved by the engineering team. I would like to see improved support from Radware DDoS. Sometimes in support, we have to log the call with their support partners rather than Radware. After ten years of experience, we know exactly what the issue is, and we understand that it cannot be handled by their support channel or partner level. Radware team always asks us to go through the partners, but sometimes we have found that the issue cannot be handled by the partners. After the partners fail to resolve the issue, it goes to the Radware team. At that time, one to two days of required timeline gets increased by one to two days. If Radware came into immediate action and resolved the issue rather than relying on their service partners, it would be better. After ten years, we have the knowledge of troubleshooting, and we understand that the issues we are facing with Radware can only be resolved by their team. However, due to their policy, they insist we move through the partner first, and only after the partner fails do they escalate to Radware. During that troubleshooting period of twenty-four to forty-eight hours, we remain in an unresolved state with the reported issue.
