Edge Scan Sensor: the lowest-cost way to see a remote LAN
Remote offices, warehouse VLANs, clinic branches, and ISP-router flat networks share one problem: no always-on workstation.
Traditional RMM discovery assumes a managed PC stays online. Traverse-style site scanners assume you will ship an appliance subscription. Dual-Strike XISEM solves the gap with the Edge Scan Sensor — a headless Linux collector built for Raspberry Pi and other arm64 boxes that lives on the customer LAN and phones home to your console.
Who it is for: MSPs and MSSPs shipping plug-and-play sensors to client sites. Direct commercial clients with multi-site footprints. Any practice that needs nominated site scans and network inventory where a full desktop agent is impractical.
Why partners call it a game changer: Commodity hardware, a free public installer, per-asset platform pricing, and the same correlation engine as your Windows fleet — without a second NMS bill or a workstation burning power overnight.
Lowest total cost of ownership in the edge sensor category
We are comfortable saying this plainly: the Edge Scan Sensor is among the lowest-cost edge discovery options you can deploy today.
Here is the math most MSPs run:
• Cost line: ----------- · Edge Scan Sensor: ------------------ · Typical alternatives: ----------------------
• Cost line: Hardware · Edge Scan Sensor: Bring your own Raspberry Pi Zero 2 W, Pi 3, Pi 4, or Pi 5 — often thirty-five to seventy-five dollars · Typical alternatives: Proprietary appliance — hundreds to thousands
• Cost line: Software install · Edge Scan Sensor: Free public arm64 installer from dual-strike.com · Typical alternatives: Appliance license or per-site scanner SKU
• Cost line: Power draw · Edge Scan Sensor: Roughly three to five watts — pennies per month · Typical alternatives: Full desktop or NMS appliance — tens of watts
• Cost line: Platform billing · Edge Scan Sensor: Per managed asset on Dual-Strike XISEM — servers, IoT, and infrastructure count transparently · Typical alternatives: Per-user RMM pricing hides infrastructure
You are not buying a locked appliance. You are enrolling a first-class infrastructure asset on the same platform that runs your agents, browser security, and compliance mapping.
Public installer one-liner: run the latest arm64 installer from dual-strike.com/downloads — search for XISEM EdgeSensor Linux arm64, or use the curl command shown in Infrastructure → Edge Sensors when you mint a ZeroConfig pack.
MSP partners also use Edge Sensor Prep — a Windows USB writer that stages ZeroConfig bundles before a Pi ships. Download from MSP downloads in the console or Infrastructure.
What the Edge Scan Sensor does
On-LAN discovery
The sensor runs native LanDiscoveryEngine sweeps from inside the customer network:
• ICMP reachability
• ARP and neighbor tables for MAC quality on Linux
• Reverse DNS
• TCP banner checks
• SNMP for switches, routers, printers, NAS, VoIP, cameras, and IoT
Discovered devices flow through ingest-network-discovery into your asset inventory and topology views — correlated with agents, identity, and EDR evidence on the platform.
Always-on when workstations sleep
Workstations go home at five p.m. The Pi does not. Default forty-five-minute LAN sweep cadence keeps inventory fresh on nights and weekends — the overnight visibility badge you will see in Infrastructure when minting a ZeroConfig pack.
Site scan nominations
Nominate the sensor in Infrastructure → Site Scan Settings the same way you nominate a workstation scanner. Policy arrives via get-agent-scan-policy. Heartbeats confirm the sensor is alive.
Registered infrastructure asset
The sensor is not a shadow process. It provisions as device_class=infrastructure with asset_role=edge_scan_sensor — visible in inventory, health dashboards, and compliance scope.
Agentless SNMP path
SNMP polling from the on-net collector is on the active roadmap for full parity with workstation agentless collectors. MSPs deploying today get LAN discovery and periodic sweeps; SNMP depth expands without replacing hardware.
Four provisioning modes — ship how you sell
• Mode: ------ · Best for: ---------- · What happens: --------------
• Mode: MSP pre-config · Best for: Known client before ship · What happens: ZeroConfig bundle with Gateway token on USB
• Mode: Identity enroll · Best for: Label with company and email · What happens: Auto-provision on first boot
• Mode: Phone home · Best for: Blank ship to stock · What happens: MSP claims in Unclaimed Agents and assigns tenant
• Mode: Site label · Best for: Multi-site MSP · What happens: site_label maps to client site on every payload
Hardware identity — serial, model — is read from Linux device tree for matching and audit.
MSP deployment workflow
Step one — Mint ZeroConfig in the console
Open Infrastructure → Edge Sensors. Select client and site. Generate a ZeroConfig pack with credentials, installer URL, and ship checklist.
Step two — Stage USB with Edge Sensor Prep
Import the bundle JSON into XISEM Edge Sensor Prep on Windows. Write xisem-edge-sensor/ to USB — config, environment, and README for the bench tech.
Step three — Flash and ship the Pi
Flash Raspberry Pi OS Lite 64-bit with Raspberry Pi Imager. Copy the flash kit boot overlay or USB staging folder. First-boot script expands the filesystem, applies MSP overlay, runs the installer, and reboots clean.
Supported boards: Pi Zero 2 W, Pi 3, Pi 4, Pi 5, and generic arm64 or x64 headless Linux.
Step four — Nominate and verify
In Site Scan Settings, nominate the sensor for LAN scans. Within one harvest cycle, confirm assets appear in Infrastructure and topology views.
Console routes: /infrastructure?tab=edge-sensors · /infrastructure?tab=site-scans · /admin/unclaimed-agents
Benefits for MSPs, MSSPs, and direct clients
Close the remote-office discovery gap. Branches without a server or always-on PC finally appear on your map — the same gap legacy Traverse-style scanners addressed, without a proprietary box.
ISP-router and flat LANs. Discovery runs on-net. No dependency on cloud-only scanning that cannot see private RFC1918 space.
One correlated story. Edge discoveries sit beside XISEM Agent posture, Anti-Venom browsing telemetry, M365 sign-ins, and EDR detections in the Asset modal — not a siloed NMS export.
Transparent economics. Per-asset pricing means a Pi sensor and a printer both count clearly. No hidden per-user tax on infrastructure.
Scale with your fleet. Ship ten Pis to ten sites for less than one enterprise appliance line item. Spares are a thirty-dollar board, not a return merchandise authorization.
Direct client fit. Commercial IT teams with warehouses, clinics, or franchise locations get site visibility without leaving a desktop online or buying a second platform.
Edge Scan Sensor vs USB Prospecting Tool
• --- · USB Prospecting Tool: ---------------------- · Edge Scan Sensor: ------------------
• Purpose · USB Prospecting Tool: Pre-contract assessment · Edge Scan Sensor: Persistent enrolled asset
• Hardware · USB Prospecting Tool: Technician laptop or USB stick · Edge Scan Sensor: Raspberry Pi on-site
• Duration · USB Prospecting Tool: Point-in-time visit · Edge Scan Sensor: Continuous sweeps
• Install · USB Prospecting Tool: No agent — read-only scan · Edge Scan Sensor: Headless service, no tray
• Best moment · USB Prospecting Tool: First sales meeting · Edge Scan Sensor: After client signs
Use both: USB Prospecting wins the deal. Edge Sensor keeps the branch visible after onboarding.
Honest limitations
• SNMP and SSH agentless depth on the sensor is still expanding — LAN discovery and periodic sweeps are production-ready; full agentless parity is on the roadmap.
• Flash kit ships as boot overlay plus installer — not a single pre-baked image file. MSPs use Pi Imager plus Edge Sensor Prep for repeatable ship kits.
• Cloud-only SaaS workloads appear through identity and browser signals, not L2 maps — pair edge discovery with Anti-Venom and M365 Gateways.
Talk track
"We drop a forty-dollar Raspberry Pi on your branch network. It discovers printers, switches, IoT, and rogue hosts overnight — and feeds the same Dual-Strike console as your desktops. No appliance subscription. No PC left running. When you are ready, we nominate it for site scans and you see the branch on the same map as headquarters."
