Checked on 26 October 2026 against each app's US App Store listing (Fing). "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. If something here is out of date, email support@netsamuraiapp.com and it will be corrected.

What Fing does well
Fing is the best-known network scanner, with detailed device recognition, internet speed tests, ISP outage and rating data, and alerts by phone and email. With the Fingbox hardware it adds blocking of unknown devices, parental controls, bandwidth analysis and network vulnerability analysis.
Where NetSamurai is different
Fing's listing puts open-port detection and network vulnerability analysis among the features you add with a Fingbox. NetSamurai runs read-only security checks from the iPhone or iPad itself, with no extra hardware: risky services such as Telnet and SMBv1, password pages without encryption, outdated TLS, and software versions and device models matched against reviewed CVEs and CISA's Known Exploited Vulnerabilities catalog. Each finding comes with a plain-language fix. NetSamurai also collects no data, where Fing's privacy label lists several kinds of data not linked to you.
