Network Intrusion Detection vs NearSight

Mobile Intrusion Detection System -Deep Network Visibility, Mobile-First Stop wondering what's on your network. NetScanner gives you instant, detailed visibility into every device on your LAN with two scan modes: Turbo Scan - Sub-minute sweep of your subnet. ARP discovery + top ports (SSH, HTTP, HTTPS, SMB, RDP). Fast enough to run on every WiFi connect. Deep Scan -Full protocol analysis across 60+ ports including Kubernetes API, Docker, Grafana, Prometheus, ESXi, databases, and message queues. Probes each web port for HTTP response headers and page titles. Discovers services via mDNS/Bonjour, SSDP/UPnP, LLMNR, NetBIOS, and WSD. Smart Device Tracking - Devices are assigned a permanent UUID on first discovery and matched across scans using weighted trait-based similarity scoring (hostname, Bonjour name, MAC, open ports, web server signatures, page titles, vendor, IP). No more lost devices when an IP changes or a service restarts. Change Detection & Alerts - Push notifications for new devices, IP changes, and devices going offline. Per-device change logs track every detected change with timestamps and old/new values. Devices offline for 7+ days are flagged for cleanup. Built for Home Labbers - Recognizes VMware ESXi, Kubernetes NodePorts, Docker, NFS, iSCSI, Grafana, Prometheus, Elasticsearch, RabbitMQ, and dozens more. Vendor identification from MAC OUI lookup. Auto-classifies Apple, Samsung, Google, Amazon, Raspberry Pi, and smart home devices. Privacy-First - Runs entirely on your device. No cloud, no accounts, no telemetry. Export your device list as JSON. Scheduled background scans with configurable intervals (1h / 6h / 24h). Multi-network aware - only scans the network you've selected. Authorize & Monitor - Mark trusted devices as verified. Nickname your devices. Spot the unknown ones instantly.

See the hidden world around you. NearSight listens for the Bluetooth Low Energy (BLE) signals that nearby devices are constantly broadcasting and decodes what they actually are. Earbuds, watches, fitness trackers, beacons, smart-home sensors, item trackers, and more turn from anonymous radio noise into a clear, readable list right on your iPhone. WHAT YOU CAN DO • Scan live. Watch nearby devices appear in real time, sorted by how close they are. • Know what's there. NearSight recognizes a growing catalog of device types and shows make, model, and what each signal means, not just a cryptic address. • Notice the unexpected. Surface unknown or unfamiliar devices around you and decide for yourself what belongs. • Go deeper. Open any device to inspect its raw advertisement, signal strength, and parsed technical details. OPTIONAL AI INSIGHTS Turn on AI to get plain-language explanations of what NearSight is seeing. Bring your own Anthropic or OpenAI API key, or run a compact model entirely on your device. Your choice. AI is completely optional and stays off until you enable it. PRIVATE BY DESIGN Scanning happens on your iPhone. NearSight works fully offline and shows what it sees to no one but you. AI insights and anonymous telemetry are strictly opt-in and off by default. Nothing leaves your device unless you turn it on. No ads, no third-party tracking, no account required. WHAT NEARSIGHT CAN (AND CAN'T) SEE NearSight decodes the Bluetooth signals that devices broadcast but it can't see everything: • Not every device is recognized. New or niche hardware may show up as Unknown until we've researched it and added support. • Some devices are intentionally excluded. We don't surface certain safety-sensitive devices (for example personal panic buttons), because revealing someone's private safety equipment could put them at risk. However, AI Insights may identify such devices. • It only sees Bluetooth. Devices that are powered off, not currently broadcasting, or that use other radios (Wi-Fi-only cameras, wired, or cellular devices) are invisible to NearSight. NearSight is a Bluetooth explorer, not a safety or security device, bug sweeper, or hidden-camera detector. It cannot guarantee it will find every tracker, camera, or listening device near you, and not seeing something here does not mean it isn't there. If you have a real safety concern, use dedicated tools and contact local authorities. Questions, or a device you'd like us to identify? Email hello@nearsight.one.
