Nmap vs nPerf

Nmap is a free, open-source utility for discovering networks and auditing security. It uses raw IP packets to identify available hosts, services and versions, operating systems, and packet filters or firewalls. Scanning options include TCP and UDP ports, OS and version detection, and ping sweeps. Network administrators can use it to inventory systems, plan service upgrades, and monitor host or service uptime. The Nmap Scripting Engine runs bundled or user-written scripts in parallel for networking tasks such as discovery and vulnerability checks. The suite also includes Zenmap, a graphical interface and results viewer; Ncat for data transfer and debugging; Ndiff for comparing scan results; and Nping for packet generation and response analysis. Most port-scan types require privileged access to send and receive raw packets, although unprivileged users can run connect and FTP bounce scans. Nmap is not a comprehensive vulnerability scanner. End-user use is free, but redistribution in commercial products requires an OEM license. Quarterly OEM licenses start at $9,980.00 per 3 months for eligible small or startup companies.

nPerf is an internet connection measurement service for speed, latency, browsing, streaming, and mobile signal strength. Its speed test uses a worldwide network of dedicated servers and an algorithm to measure download speed, upload speed, and latency. Mobile apps offer separate speed, browsing, and streaming tests, keep test history with map locations, and allow results to be shared. nPerf says these tests can use up to two times less data than competing tests and include a configurable data threshold indicator. PC and Mac applications test connections up to 10 Gb/s. Free services include tests, instant comparisons, and speed and mobile coverage maps; an account adds web dashboards, statistics, and cloud backup. Premium costs $2 a year. For telecom operators, Analytics supplies crowdsourced network data, more than 250 KPIs, live analysis, and raw data export. The service is available on Android, iOS, Linux, macOS, web, and Windows.
