Unified security platform has simplified daily network protection and accelerated troubleshooting
Fortinet FortiGate is generally easy to manage, but there are a few areas where it could be improved. The interface can become complex when managing a large number of firewall policies, and better policy search organization and reporting would be helpful. Firmware upgrades can also require careful planning and testing, especially in production environments. Troubleshooting some advanced issues may require deeper CLI knowledge or assistance from Fortinet support, and more advanced automation and AI-assisted troubleshooting within the management interface would be beneficial, such as clear recommendations for policy optimization, configuration issues, and security events. These improvements could make day-to-day administration even more efficient. More AI-driven capabilities for day-to-day administration would be valuable, especially for troubleshooting, policy optimization, and identifying potential configuration issues. More intelligent recommendations based on traffic patterns and security events could help administrators respond faster. More advanced reporting and dashboards that can be easily customized for different teams and management requirements would also be helpful, while better automation for routine tasks, firmware planning, and configuration validation would further reduce manual effort.
