Gateway Deployment
In a typical gateway deployment scenario, a single STM150 appliance is installed at the gateway –
between the firewall and the LAN core switch – to protect the network against all malware threats
entering and leaving the gateway. Installing the STM150 behind the firewall protects it from DoS
attacks.
