About

Essential NetTools is a set of network scanning, security, and administrator tools useful in diagnosing networks and monitoring your computer's network connections. It's a Swiss Army knife for everyone interested in a powerful network tool kit for everyday use. Displays a list of your computer's inbound and outbound network connections, including the information on open TCP and UDP ports, IP address, and connection states. What makes it different from other NetStat utilities is the ability to map open ports to the owning application. Configurable alerts for incoming and outgoing connections are also available. An advanced TCP port scanner that allows you to scan your network for active ports. This tool features both conventional (full connect) and stealth (half-open) scanning modes.

About

Subnetlens is a local-first Windows desktop app for network discovery, LAN monitoring, and IT troubleshooting. It scans and classifies devices, builds an interactive topology map, tracks per-device port and service history, listens for mDNS/SSDP device activity in real time, and includes 26 built-in diagnostic tools such as ping, traceroute, DNS lookup, port scan, WHOIS, GeoIP, TLS checks, HTTP header inspection, and more. Pro features include Radar monitoring, Prometheus metrics, scheduled scans, risk scoring, HTML reports, IPAM, webhooks, encrypted credential vault, SNMP topology, and multi-network profiles. Scan data stays on the user's machine unless they explicitly export it, enable webhooks, or expose the Prometheus endpoint. Subnetlens is built and code-signed by HELIOSOFT LTD and is available as a free version with an optional $79 one-time Pro license.
