Featured Reviews

RonaldoDE Melo - PeerSpot reviewer
Protects connection and servers from direct access with control access feature
The initial setup is very simple. The issue is that it achieves high output across all its features, specifically the output ports. This affects the customer's solution because sometimes, the customer is even aware of the user's activity on certain servers. If you have all the necessary information, we can quickly deploy the solution within two to three days. The size of the Thunder ADC depends on its configuration. For example, the cache converter typically includes more than two rack units, often requiring at least three rack units for adequate space. I rate it a ten out of ten, where one is difficult, and ten is easy.
IshtiaqKhalil - PeerSpot reviewer
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
