Buy Network Tap VERIFIED
The LAN Tap Pro is a passive Ethernet tap, requiring no power for operation. There are active methods of tapping Ethernet connections (e.g., a mirror port on a switch), but none can beat passive taps for portability. To the target network, the LAN Tap looks just like a section of cable, but the wires in the cable extend to the monitoring ports in addition to connecting one target port to the other.

The LAN Tap is designed to monitor 10BASET and 100BASETX networks. It is not possible for an unpowered tap to perform monitoring of 1000BASET (Gigabit Ethernet) networks, so the Throwing Star LAN Tap intentionally degrades the quality of 1000BASET target networks, forcing them to negotiate a lower speed (typically 100BASETX) that can be passively monitored. This is the purpose of the two capacitors (C1 and C2).
Like all passive LAN Taps, this device degrades signal quality to some extent. Except as described above for Gigabit networks, this rarely causes problems on the target network. In situations where very long cables are in use, the signal degradation could reduce network performance. It is a good practice to use cables that are not any longer than necessary.
With its portability and price, the LAN Tap Pro has become a go-to device for network monitoring among information security professionals. Designed by and for the open-source community, this passive tap is a useful addition to your field kit
A Network Tap is a passive device that provides a method to easily access the traffic on the network segment while maintaining network integrity; no need to break the link each time. Network performance will not be affected by power loss.
Network Taps allow you access to your network to get a copy of the data to all kinds of devices, packet analysers like Allegro Packets, or to to your network troubleshooting tools such as NetAlly EtherScope, or even if you need to get your IDS to exist in many places around the network by using multiple taps.
Organizations require dynamic network intelligence to provide security and ensure applications are running their best. But the larger a network grows, the harder it becomes to monitor. Blind spots can easily compromise your ability to ensure network quality. Traditional monitoring methods, such as port mirroring, can be costly and add layers of complexity. And some monitoring solutions negatively impact network availability. With networks growing faster than ever, now is the time for a high-performance, scalable monitoring solution.
The Keysight family of network tap products, including patch taps, optical fiber taps, and copper taps provides complete visibility into network traffic to help you maintain optimal performance and security. Network taps, installed directly to the network, are plug-and-play, and do not require costly hands-on management.
Garland Technology is committed to educating the benefits of having a strong foundation of network visibility and access. By providing this insight we protect the security of data across your network and beyond.

Condé Nast is launching its podcast network after seeing 28 million hours of listen time across its podcasts last year. So far this year, downloads of its in-house podcasts have spiked by 26%, the company said. (Signs that it was investing more into podcasts appeared earlier this year, when it formed podcast, film, and TV studios for its biggest verticals.)
Gigamon serves the world's more demanding enterprises and public sector agencies, enabling them to harness actionable network-level intelligence to amplify the power of their cloud, security and observability tools.
A network TAP (test, terminal, or traffic access point) is fundamental to acquiring network traffic. As part of the Gigamon Deep Observability Pipeline, Gigamon network TAP technology provides access to the traffic required to secure, monitor and manage your network infrastructure continuously and efficiently. TAPs are the first step in the process of gaining consistent visibility across your physical, virtual and cloud infrastructures, and each tapped link assures access to 100 percent of your network traffic.
In physical networks, a network TAP is deployed in a network link connected between the interfaces of two network elements, like switches or routers, and is treated as part of the infrastructure. In the virtual world, network TAP deployment varies depending on the environment.
Passive fiber-optical network TAPs create identical copies of all network traffic at full bandwidth. They do not require power or management and do not actively interact with other components on the network.
When native packet mirroring is not an option, virtual network TAPs (vTAPs) are used in network function virtualization (NFV) and in private and public cloud infrastructures to gain access to East-West and North-South traffic within the hosting environment. Depending on the virtual machine or container technology in use, different tapping functions are available.
CTI 2500-TAP RS-485 network taps can be used for construction a remote I/O network. These taps use an impedance-controlled design for highest noise immunity and include built-in termination resistance which can be easily switched in- or out- of the circuit using a toggle switch. They also include an electrical noise bleed path to chassis ground which can improve the noise immunity of your network.
The SINGLEstream SS-G4C8C4S Multi-Link Copper Mesh Tap with 12 Monitor Ports is a compact and flexible solution for collecting, aggregating, and distributing data from multiple sources to monitoring tools. It is a multi-link tap that can use 4 copper 100/1000 connections. The SFP+ ports can be used as 10G copper or fiber links. They can serve as additional monitor ports and support DAC (Direct Attach Cables). Datacom SINGLEstream copper network tap with 4 x 10/100/1000 network tap (2 ports per tap), Eight copper 10/100/1000 BT ports and four SFP+ any-to-any ports.
A network TAP is a passive device that allows easy access to traffic on the network segment without having to disconnect each time. Datacom Systems' Link Aggregation TAPs provide an excellent solution for 247 monitoring of full-duplex Ethernet links.
While conventional standard 10/100 network TAPs provide full-duplex monitoring of all traffic on a network link, they transmit the data to the monitoring device (e.g. analyser, IDS, probe) in two separate half-duplex streams. This requires not only that the monitoring device has two network interface cards, but also that the device is able to combine and process both data streams to monitor both sides of the call. Not all monitoring devices have this capability.
Taps allow access to one's network to get a copy of the data to all kinds of devices, packet analysers or data to network troubleshooting tools. Also, if administrators need to deploy IDS in many places in the network by using multiple APs.
Monitoring 10G links with 1G tools is also possible - some aggregation taps can also filter traffic. This feature allows the administrator to tap 10Gbps but send the data to a 1Gbps analysis tool or IDS system. This means that companies don't necessarily need to upgrade their tools, even if their network is getting faster.
The Ditto Network Tap Module adds professional forensic network capture to the Ditto family's long list of capabilities. With a Network Tap Module attached, the Ditto or Ditto DX Forensic Fieldstations can capture all network activity for further analysis, storing captured packets on external drives.
It may also be necessary to monitor multiple network segments simultaneously and to aggregate the data in the direction of your monitoring tools, or to replicate them simultaneously to more than one forensics tool. Permanent solutions can be best implemented with our Modular TAPs.
NEOX NETWORKS provides network access devices that can collect network data for legal reasons. Our products help you achieve this by monitoring one or more network connections in compliance with statutory guidelines.
An IDS analyses the network traffic and warns you of threats that might potentially cause damage to your network. To carry out this task effectively, you need a network connection that allows the IDS to examine all traffic.
