Protect inspection continuity without forcing traffic to stop. This Trend Micro dual-port 1 GbE copper bypass card is designed for DDI-520/1200 platforms that run TLS inspection in-line and need a hardware path that can keep traffic moving during service events. The copper interface and bypass behavior make it a practical fit for environments where availability is part of the security requirement. In production networks, the difference between a standard adapter and a bypass card is operational control. A bypass card is selected when the appliance sits directly in the traffic path and the organization wants a defined fallback behavior if the device is offline, rebooting, or under maintenance. That helps reduce disruption to business-critical connectivity while preserving the inspection architecture. This module is a focused fit for teams standardizing on Trend Micro DDI appliances and looking for a component aligned to inline TLS inspection rather than a general networking accessory. It supports a cleaner deployment model for security teams that value predictable failover behavior and hardware matched to the platform.
