LAN Scanner & Diagnostics · macOS & Windows

Kitsune

A cunning network scanner that maps every device on your LAN, probes the services they expose, and sniffs out the problems hiding in the wiring — then hands you a prioritized list of what to fix.

What Kitsune does

From a single scan to a full picture of your network's health.

Device discovery

ARP and host sweeps find everything on the segment, with hostnames resolved via mDNS, NetBIOS, and DNS — and vendor lookup from a bundled OUI database.

Port & service scan

A batched SYN scanner maps open ports and flags risky exposed services — Telnet, unencrypted MQTT, stray HTTP — with plain-English fixes.

Security findings

ARP spoofing, rogue DHCP, multicast leaks, and more — each rated HIGH / MEDIUM / LOW with a clear recommendation, all in one panel.

VLAN, STP & topology

VLAN-aware spanning-tree sniffing (PVST+), per-VLAN SNMP, switch discovery, and a topology map that shows how it all connects.

Storm & latency checks

Rate-based broadcast/multicast storm detection names the culprit MAC, while latency, jitter, and bufferbloat tests grade your link.

Exportable reports

Save the whole picture as JSON, CSV, text, or HTML — ready to hand to a client, a colleague, or your future self.

A look inside

Real captures from a full Kitsune LAN scan.

Kitsune findings view with prioritized security findings — **Prioritized findings.** Every issue Kitsune uncovers — mDNS leaks, ARP spoofing, exposed Telnet/MQTT — ranked HIGH/MEDIUM/LOW with the affected host and a recommended fix.

Kitsune host inventory with vendors, hostnames, and open ports — **Device inventory.** Every host on the segment with IP, MAC, vendor, hostname, and open ports — Sonos, Apple TV, cameras, smart plugs, all identified at a glance.

Kitsune SNMP switch topology with port maps and STP status — **Switch & port topology.** An SNMP sweep maps your switch hierarchy — per-port devices, link speeds, STP status, and VLAN assignments, gateway down to the edge.

Kitsune multicast IGMP topology view — **Multicast & IGMP.** See the querier, every group, and who joined what — and get flagged when foreign multicast is leaking across a VLAN boundary.

Kitsune multicast group membership and senders — **Group membership.** Drill into each multicast group to see its members, the senders generating traffic, and report counts across the segment.
