Garland Technology: Network Visibility
Garland Technology is an industry-leading provider of network TAPs (Test Access Point) and network packet broker solutions. Garland‘s mission is to secure the OT and IT network in order to identify threats more quickly and thus eliminate them more quickly.
With Garland's TAP to Tool philosophy puts the focus on the security and monitoring tools to ensure optimal performance.
Product & Function Overview
| Network TAP | A Network TAP is a purpose-built hardware device that allows you to access and monitor your network traffic by copying packets without impacting or compromising network integrity. The TAP allows network traffic to flow between its network ports without interruption, creating an exact copy of both sides of the traffic flow, continuously, 24/7, 365. The duplicate copies are sent out the monitoring ports of the TAP and are then used for monitoring and security analysis. |
| Network Packet Broker (NPB) | A Network Packet Broker is a hardware device that provides a collection of monitoring tools with access to traffic from across the network. An NPB receives data from a number of network links then acts as a broker, dealing the relevant data out to the connected monitoring tools. A NPB has advanced functionality to aggregate, load balance, filter, and deduplicate traffic to improve tool efficiency and reduce CAPEX costs. |
| Hardware Data Diodes | Hardware Data Diodes and Data Diode TAPs are useful and cost-effective solutions to help provide an additional layer of security in OT networks. There are situations where the use of SPAN/Mirror ports is still needed for visibility in an OT network. In these instances, it is best practice to connect the SPAN/Mirror port to a hardware Data Diode to pass the mirrored data onto the monitoring and security sensors. Using hardware Data Diodes eliminate bidirectional traffic flow ensuring that no data is passed back into the Switch Mirror port. |
| Inline Bypass | The Bypass TAP was developed specifically to resolve the problem of an inline security tool creating a point of failure. Bypass mode prevents inline devices from being a single point of failure and causing network downtime. Network downtime can be costly for organizations and add hours of work to already short-staffed security teams. In the event the device fails or if there is a power loss, the heartbeat packets that are sent from the bypass TAP to the inline device trigger the TAP to “bypass” that inline device. This leaves the network link up or triggers a failover to a redundant device. The heartbeats added to the redirected traffic have additional functionality: they allow the Bypass TAP to be aware of the health of an inline appliance. |
