Security communications processors

SIMATIC security communication processors with integrated firewall and vpn

Protect your SIMATIC automation devices

With their integrated firewall – to monitor the data flow – and VPN, security communications processors protect against data manipulation and espionage. A special benefit of the security communications processors for SIMATIC controllers is the automatic generation of firewall rules when configured using the TIA Portal. The firewall automatically approves configured communications connections, which substantially reduces the time needed for configuration and also the risk of error.
