The Tofino Security Appliance is a self-contained microprocessor-based device that provides firewall, VPN, asset management, event logging and other security services in control and automation networks. Its functionality is determined by firmware stored in non-volatile memory inside the appliance.
As part of the ongoing development and enhancement of the product, Byres Security periodically releases firmware updates that may be installed in the appliance using the Tofino Central Management Platform (CMP) software.
