Network Scanner & IP,PORT,WİFİ

Real-time network monitoring with continuous LAN scanning, live device discovery, open port detection, security analysis, and speed testing — all from your iPhone.

N3TSCAN turns your iPhone into a powerful, real-time network monitoring terminal.

Tap RUN and watch your local network come alive -- every device, every open port, every security finding streams to your screen the moment it's discovered. No waiting for batch results. No stale data. Pure live intelligence.

CONTINUOUS NETWORK MONITORING

• Live device discovery across your /24 subnet
• Streaming results -- hosts and ports appear instantly as they're found
• Continuous scan loop: automatic re-scanning every few seconds
• Stop anytime with one tap; results persist

PORT & SERVICE SCANNING

• 9 common service ports probed per host (SSH, HTTP, HTTPS, SMB, AFP, IPP, UPnP, and more)
• Parallel TCP connect probes with fast failure detection
• Pipelined architecture: port probing starts as soon as each host is found
• Per-host open port list updated in real time

SECURITY ANALYSIS

• Detects exposed Telnet, unprotected SMB shares, raw printing ports, and HTTP-only services
• Each finding includes severity, technical detail, and a recommended action
• Alerts for new/disappeared hosts and port changes between scans
• Health score computed from scan, speed, and alert data

SPEED LAB

• Internet speed: download, upload, RTT, jitter, estimated loss
• LAN throughput measurement to your gateway or any private IP
• Quick, Full, and LAN-only modes
• Live sparkline charts during measurement
• Results feed into health scoring and trend tracking

DIAGNOSTICS TOOLS

• DNS Inspector: resolve any hostname with timing
• HTTP/TLS Probe: TTFB, status code, TLS handshake duration
• TCP Endpoint Monitor: reachability check with RTT and failure streak
• Plain-language summaries for operators; technical detail in logs

AUTOMATION

• Create scan + speed profiles with custom intervals
• Hourly rate cap and charging-only guard
• Queue depth and recent activity visible on screen
• Foreground-only; no hidden background scanning

INSIGHTS & EXPORT

• Network health score (0-100) with executive headline
• KPI grid: hosts, findings, alerts, open ports, speed trends
• Export combined JSON + PDF + CSV reports
• CSV with sectioned layout: executive summary, hosts, findings, alerts, quality warnings

TERMINAL-MODERN DESIGN

• Dark monospaced UI inspired by professional security tools
• Live event feed with icons and timestamps
• Progressive disclosure: overview first, details on demand
• Consistent design system across all five tabs

PRIVACY & SAFETY

• Scans only private IPv4 ranges (RFC 1918 + link-local)
• No data leaves your device -- all processing is local
• No tracking, no ads, no analytics SDKs
• Privacy manifest included

N3TSCAN is built for network administrators, security enthusiasts, IT professionals, and anyone who wants to understand what's happening on their local network -- instantly.
