Everything in one scanner

A complete network security toolkit — built to detect, analyse, and neutralise IoT threats automatically.

LIVE
🔍

ARP Device Discovery

Broadcasts ARP requests across your subnet to identify every connected device — including those that block ICMP ping.

CVE
🐛

Live Vulnerability Lookup

Queries the NIST NVD database in real time — matching device signatures against thousands of known vulnerabilities.

⚔️

Penetration Testing

Actively tests default credentials, unauthenticated camera access, FTP, MQTT brokers, and SMB sessions.

LIVE
📡

Traffic Monitor

Live packet capture with protocol breakdown. Detects SYN floods, port scans, ARP spoofing, and ICMP floods.

🔒

Device Isolation

Instantly blocks compromised devices using Windows Firewall — no router access needed. One click to isolate or restore.

AUTO
👁

Watch Mode

Continuous background monitoring at configurable intervals. Alerts on new devices, risk escalations, and port changes.

📈

CVE Risk Scoring

Weighted 0–100 risk score per device and network-wide. Grades from Minimal Exposure to Critical Exposure.

📄

PDF Reporting

One-click professional security report. Includes device inventory, CVE findings, test results, and fix recommendations.

🕑

Scan History

Every scan stored automatically with score trends and change detection. Export full history as CSV in one click.

// workflow

How it works

Four automated stages run sequentially — from device discovery to actionable remediation.

🔍

Discover

ARP broadcast maps every device on your subnet. Double-verified to eliminate false positives.

🧠

Analyse

MAC vendor lookup, HTTP banner grab, TLS check, UPnP fingerprint, and OS detection via TTL.

🐛

Audit CVEs

Live NIST NVD query with retry logic. Full CVE descriptions, CVSS scores, and direct NVD links.

🔒

Remediate

Penetration test results, device isolation via Windows Firewall, and plain-English fix recommendations.

⚠️

Windows SmartScreen — Expected Behaviour

As an independent security tool without a corporate code-signing certificate, Windows SmartScreen may show a warning on first launch. This is normal for all new independent software.

To proceed: click "More info""Run anyway".

// system requirements

Requirements

Standalone installer — no Python, no dependencies, no manual configuration.

Operating System

Windows 10 or Windows 11 (64-bit). Must run as Administrator for ARP scanning and firewall operations.

Network

Active Wi-Fi or Ethernet on a local subnet. Internet access required for live CVE lookup via NIST NVD API.

No Dependencies

Fully self-contained installer. All libraries, drivers, and the Python runtime are bundled internally.

Scan your network
in under 3 minutes.

Runs entirely on your machine. No data leaves your network. No subscription required.
