Checked on 26 October 2026 against each app's US App Store listing (Network Analyzer). "Not listed" means the feature isn't mentioned in that app's App Store description, not that it can never do it. Privacy labels are self-reported by each developer and describe data that "may" be collected. Apps change, so check the current listing before you decide.

What Network Analyzer does well
Network Analyzer is a fast, compact toolkit: a LAN scanner with names from NetBIOS, Bonjour, LLMNR, SNMP and WS-Discovery, ping and traceroute, a port scanner that covers common ports, custom ranges or every port, whois and RDAP, a DNS lookup for many record types, full IPv6 support and detailed network information.
Where NetSamurai is different
Network Analyzer tells you which ports are open and what services usually run on them; NetSamurai reads what those services actually answer and tells you which ones are a problem. It flags risky services such as Telnet and SMBv1, password pages without encryption and outdated TLS, matches software versions and device models against reviewed CVEs and CISA's Known Exploited Vulnerabilities catalog, and explains each finding with steps to fix it. It also flags and can alert you about new devices, and collects no data.
