Traffic sensor (BETA)

If It’s on Your Network, You’ll Know About It

Traffic sensor passively observes everything communicating on your network. Gain continuous visibility and surface unknown devices with undeniable evidence and context. No predefined scope, no missed devices.

Traffic sensor is currently in open beta, available for existing customers.
  • See Everything That's Communicating

    Traffic sensor continuously observes network activity, revealing every device that is actively communicating.

  • No Scope Required

    No need to configure scan ranges. Traffic Sensor listens to the entire network, surfacing devices IT never knew to look for.

     

  • Continuous, Not Point-in-Time

    Traffic sensor runs constantly and passively, capturing transient devices, short-lived connections, and unexpected activity as it happens.

Lansweeper Traffic Sensor - Passive Network Discovery

Total Visibility

Let Your Network Define Scope

Traditional discovery depends on the scope of what teams already know. Devices added without IT involvement, contractor laptops, equipment in unscoped subnets, none of it appears. Not because the tool failed, but because nobody told it to look there. Traffic sensor flips that model to enable total visibility: any device that communicates becomes visible, whether IT knew it was there or not.

Discovery Coverage

Continuous Discovery

Capture Network Activity as It Happens

Traffic sensor continuously observes the network, detecting devices the moment they appear. A contractor laptop that connects for two days, a shadow IT tool, or a short-lived connection, nothing goes unnoticed. All of it found as it happens, not the next time someone runs a scan.

Undeniable Evidence

Turn Network Activity Into Evidence

Knowing what exists isn’t enough when incidents occur. Traffic sensor shows what systems were actually communicating at a given moment. When something goes wrong, traffic sensor gives IT and security teams the evidence to answer “what was active?” with confidence, not assumptions.

Shared Intelligence

Build Confidence Across IT and Security Teams

When traffic sensor works alongside Network Discovery, IT and security teams gain a shared, evidence-based asset intelligence foundation. IT and Security no longer operate from incomplete or conflicting lists. Instead, they see the same continuously updated picture, including visibility into AI usage across the environment.

Traffic sensor beta

Ready to get started?

The traffic sensor open beta is available for existing Lansweeper customers running cloud-based Network Discovery.

Currently supported on Linux (Ubuntu 22.04 LTS and RHEL 8). Windows support is coming soon.

  • What is Lansweeper’s traffic sensor?

    Lansweeper’s traffic sensor is a passive network discovery engine that identifies every device actively communicating on your network without requiring a predefined scope or IP range configuration. It works alongside Network Discovery to deliver total visibility: the confidence that nothing communicating on your network goes unseen.

  • How is traffic sensor different from network scanning?

    Traditional network scanning requires pre-configured IP ranges and runs on a schedule. Traffic sensor passively observes network communication continuously, with no scope to define. It finds devices that scans miss by design: contractor machines, transient connections, equipment in subnets nobody thought to include, the moment they appear.

  • Does traffic sensor replace Network Discovery?

    No. Traffic sensor extends Network Discovery, not replaces it. Network Discovery delivers deep asset context for everything IT already knows about. Traffic sensor surfaces everything outside that scope. Together they deliver total visibility: a continuously maintained, evidence-based inventory that both IT and Security work from.

  • Can traffic sensor detect unknown or unmanaged devices?

    Yes. Any device communicating on the network is detected, regardless of whether it was ever added to an inventory or included in a scan scope. This includes contractor laptops, shadow IT devices, temporary equipment, and AI tools running on unscoped endpoints. If it is communicating, traffic sensor will find it.

  • Why is continuous network visibility important for security and compliance?

    Point-in-time scans miss devices that connect and disconnect between cycles. Continuous visibility ensures nothing communicating on your network is invisible, including the transient devices most likely to surface in post-incident investigations as the entry point nobody saw coming. It also produces the evidence auditors and leadership now expect.
