Netwatch Network & Security

Find devices on your home network, check open ports and spot new devices with the security score. Plus ping, traceroute, speed test and subnet calculator.

Netwatch is a network diagnostics and security toolkit for your home network – with device scanner, port scanner, ping, traceroute, speed test and a security score.

DEVICES • Network scanner: finds devices on your current Wi-Fi subnet, a common subnet from the presets or any CIDR range you enter. • From the result list, start a ping or port scan for any device right away. • Device names are looked up via local DNS where possible. • Name devices and assign a type such as router, NAS, printer, TV or smart home. • Network map and a history of newly discovered devices and name changes.

SECURITY • Security mode flags devices that have appeared since your last scan. • Security score from 0 to 100 with clear deductions for new devices and risky open ports. • Port scanner checks 42 common TCP ports, shows each as open, closed or filtered and flags 15 of them as a security risk on a LAN. • All ratings are based only on scans you start yourself – no background monitoring.

TOOLS • Continuous ping with live stats (min, avg, max, loss). • Hop-by-hop traceroute; ping any hop individually. • Speed test for ping, jitter and download with four servers to choose from; upload is measured on the Cloudflare server. • DNS lookup, public IP, IPv4/IPv6 test and DNS resolver comparison. • Subnet calculator: netmask, network and broadcast address, host range, wildcard. • Bluetooth scanner for nearby BLE devices. • Router status for FRITZ!Box: model, FRITZ!OS version, internet connection, Wi-Fi and public IP. • Glossary of key networking terms. • Light, dark or follow system appearance.

PRIVACY Netwatch needs no account and contains no tracking or ads. The free scan shows up to 10 devices; Netwatch Pro (monthly or yearly subscription) shows every device and unlocks the port scanner, traceroute, Bluetooth scanner, FRITZ!Box status, network map and network tools. Scan results, device names and router credentials are stored only on your device; credentials are sent to your router and nowhere else.

Note: only scan networks you are authorized to scan.
