Keep TLS inspection paths available when the network changes. This Trend Micro dual-port 1 GbE copper bypass card is built for DDI-520/1200 deployments that need inline security without sacrificing traffic continuity. By using copper Ethernet and bypass behavior, it helps preserve forwarding during link events, maintenance, or appliance interruption scenarios where inspection uptime matters. For teams running DDI appliances in production, the value is in controlled resilience. Rather than forcing traffic to stop when an inline device is unavailable, a bypass card is designed to keep the path moving so critical services remain reachable. That makes it a practical fit for environments where security inspection must stay close to the traffic stream, but downtime is not acceptable. This module is a targeted hardware option for organizations standardizing on Trend Micro DDI platforms and looking for a purpose-built bypass component rather than a generic adapter. It is suited to infrastructure teams that need predictable behavior, clean integration, and a hardware choice aligned to inspection-focused deployments.
