Angry IP Scanner vs Fing Security

Angry IP Scanner is a free, open-source desktop tool for scanning IP addresses and ports. It accepts address ranges, random addresses, or files in any format as scan input. The scanner checks whether hosts respond to pings and can optionally resolve hostnames, identify MAC addresses, and scan ports. It also supports NetBIOS information, favorite IP ranges, web server detection, and customizable openers. Java plugins can extend scanning and data gathering with fetchers, pingers, exporters, and feeders. Results can be saved as CSV, TXT, XML, or IP-Port list files, and a command-line interface is available. It runs on Linux, macOS, and Windows under GPLv2. The maker says installation is unnecessary and that the software can be copied and used anywhere. It is described as particularly useful to network administrators monitoring and managing networks. The FAQ notes that some antivirus vendors have flagged the older ipscan.exe, while saying version 3.x is not detected.

Fing Security checks routers and networks for vulnerabilities, open ports, and threats. Scheduled router checks look for known vulnerabilities, outdated firmware, DNS hijacking risks, and exposed management interfaces. It can alert users when an unknown device joins and show that device's brand, model, and type. Fing also scans connected Wi-Fi networks for cameras and spy devices using a database of over 12 million known camera models. Fing Agent can run on Raspberry Pi, Docker, or NAS for ongoing automated checks. Home Assistant, IFTTT, and the Fing Local API support presence data, network events, and custom automation. The maker identifies IT consultants, MSPs, and small businesses as users for client audits and security monitoring. The free plan allows up to three scans per day; scheduled vulnerability scans and continuous threat detection require a subscription. Premium costs $7.99 per month and Professional costs $16.99 per month. Fing Desktop is available for Windows and macOS, but not currently Linux. Fing says it is SOC 2 Type II certified.
