Network Intrusion Detection vs NetGuard

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.

NetGuard is a free iPhone app that scans your WiFi network in one tap and lists every connected device with a friendly name, type, IP address, and the services it exposes. It flags new, returned, and missing devices so you always know what changed and can spot anything that should not be on your network. NetGuard is free and ad supported, with an optional one-time NetGuard Pro purchase (no subscription, ever) that removes ads and adds deeper security tools. FREE - Scan your WiFi and see every device - Device details: name, type, IP, Bonjour services - Current network, connectivity and public IP - Speed test: download, upload and ping - Ping and DNS lookup tools NetGuard is free to use and ad supported. NETGUARD PRO (one-time purchase, no subscription, ever) - Removes all ads, permanently - Network security score with plain language fixes - New device alert log: a history of who joined your WiFi - Background intruder alerts - Name and track your devices - What changed: new, returned and missing devices - Port scanner, traceroute, Wake on LAN, router security check - CSV and PDF export Pay once and keep it forever. No subscription. Privacy first: Your network scan history is stored locally on your iPhone. Note that iOS does not expose MAC addresses to apps, so device identity is based on names and services. Where available, you can explore recommendations for our other apps. They load online; views and taps are counted as daily totals without personal profiles or user/device identifiers.
