When it comes to networks, the word "Security" is often associated with complexity and high-cost. Let's not forget intrusive. And the exotic skills you'll need to understand what you are doing. Well, it doesn't have to be this way. Our products will completely change your perspective. Our firewalls are purpose-built for securing M2M applications.
PortBloque E is a specialized firewall that protects serial Modbus devices from Internet attacks. It combines firewall operation and Modbus TCP/UDP deep packet inspection (DPI) to block everything that's unwanted or harmful. The simple web interface makes setup easy. Operators can control Modbus traffic by slave IDs and function codes, and block a command that repeats too soon.
This product has reached end of life (EOL). Support is for existing customers only.
