Hardware for authorised network assessments

Network implants and LAN taps provide controlled ways to observe, connect to and assess wired infrastructure during approved penetration tests, red-team exercises, research and training. Use them only on networks and equipment where you have explicit permission. Document placement, handling, data access and removal as part of the engagement.

For passive or active wired testing, the Plunder Bug LAN Tap is a pocket-sized Smart LAN Tap with USB-C connectivity. Plunder Bug is suited to portable monitoring and active engagements. The Packet Squirrel Mark II is a compact Linux-based network tool for packet sniffing, VPN tunnelling and other authorised assessment workflows, while Packet Squirrel Advanced (TAA) provides an option for buyers with relevant procurement requirements. Packet Squirrel hardware is a practical choice when a portable network assessment kit needs more than a simple tap.

Shark Jack is designed as a compact Ethernet assessment platform for running authorised payloads. Shark Jack Display adds an integrated display for status and interaction. The LAN Turtle Hub supports LAN Turtle deployments where additional connectivity or a hub-style setup is required. The Screen Crab is intended for authorised video capture and remote viewing workflows, while PiKVM v4 Plus provides hardware-based remote KVM access for systems you are permitted to administer.

Choosing the right Ethernet tools

  • Choose a LAN tap for traffic visibility, or a network implant for controlled, programmable assessment tasks.
  • Select a Packet Squirrel for compact Linux-based network workflows, a Shark Jack for portable Ethernet payloads, or a LAN Turtle setup for remote access testing.
  • Use the Micro Ethernet Switch or Ethernet Coupler when a test configuration needs basic wired connectivity or an inline connection accessory.
  • The Glytch Ethernet Mod for Pager is a specialist accessory for compatible pager-focused research setups.

Buying in the UK and Ireland

Prices are shown in GBP or EUR, with USD also available. VAT is calculated at checkout. Check your organisation’s procurement, data-handling and engagement policies before deployment. Radio-capable equipment must comply with applicable UK or Irish spectrum rules. Ofcom states that radio use requires a licence or a specific exemption, and transmission-capable devices need particular care. Review lock-picking and access-tool laws where relevant, and check UK or EU export-control requirements for controlled dual-use equipment before sending hardware across borders.

Frequently asked questions

What is a LAN tap used for in security testing?

A LAN tap provides a controlled connection for observing wired network traffic during an authorised assessment. Select the appropriate tap and configuration for the network link, document the test scope, and avoid collecting traffic outside the agreed engagement.

What is the difference between a LAN tap and a network implant?

A LAN tap is primarily used to provide traffic visibility, while a network implant is generally a programmable device used for approved assessment workflows such as monitoring, tunnelling or payload execution. The correct choice depends on the test plan and access available.

Which product suits a portable network assessment kit?

Packet Squirrel Mark II, Packet Squirrel Advanced, Shark Jack, Plunder Bug and LAN Turtle hardware are compact options for different wired-network workflows. Compare their published features, required connections and intended use against the engagement scope.

Are these tools legal to use in the UK and Ireland?

Their lawful use depends on authorisation, configuration and local regulation. Obtain explicit permission before connecting hardware to a network. Review radio transmission rules, access-tool legislation, data-protection duties and export controls before purchasing or deploying equipment.
