Honeywell comments on Tofino

"In today's environment it is not sufficient for plants to simply depend on perimeter firewalls for security.  They need multiple levels of security, and the Honeywell Modbus TCP Firewall, based on Tofino technology, provides our clients with a robust security solution from outside threats and improper network introductions."
