Featured Reviews

OusaidAbaz - PeerSpot reviewer
Integrates load balancing efficiently within existing technology environments
FortiADC provides load-balancing capabilities needed for integration with other Fortinet platforms. It allows for the creation of virtual IPs and applying various algorithms for traffic management. Although it offers fewer algorithms than competing platforms like F5, its capability to manage load balancing makes it valuable. The security features depend on the environment, relying on firewalls like FortiGate.
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
