Garland Technology

Garland Technology manufactures network visibility hardware: network TAPs, packet brokers, data diodes, and inline bypass switches that sit passively on a network link and copy traffic out to monitoring and security tools without disrupting production traffic. The core value proposition is foundational rather than flashy — intrusion detection systems, NDR platforms, packet capture appliances, and forensics tools are only as good as the traffic they actually see, and Garland’s hardware is what guarantees that visibility instead of relying on a switch’s SPAN/mirror port, which can silently drop packets under load.

Founded in 2011 and headquartered in Buffalo, New York with a secondary office in Richardson, Texas, Garland has built a full product line around IT and OT network visibility, including bypass TAPs for inline security appliances (so a firewall or IPS failure doesn’t take down the network) and data diodes for one-way, air-gapped data transfer in high-security OT environments.

Garland competes against larger, more diversified players like Gigamon and Keysight (Ixia) in the network visibility/packet-broker market. As a privately held, apparently self-funded company with no disclosed venture rounds, its growth has been steady rather than headline-making, and its differentiation is depth and reliability in a narrow hardware category rather than a platform play; it is the kind of vendor that shows up as critical infrastructure behind a security stack rather than as the security product itself.
