For enterprise clients, downtime is not an option. AhnLab firewall appliances support Active-Active and Active-Standby High Availability configurations. This means if a primary firewall unit fails, a secondary unit takes over immediately without interrupting active sessions. This seamless failover capability is critical for financial institutions and manufacturing environments where milliseconds of latency matter. | Feature | AhnLab TrusGuard | Fortinet FortiGate
