What Nmap Online Scan is
Nmap Online Scan is a web service for online network scanning and port discovery using Nmap. It offers Quick, Service, Aggressive, and Custom scan modes; users can set a port range and timing, and enable service-version or operating-system detection. The service runs in the cloud and supports JSON and CSV exports. Free accounts can run three scans per day, resetting at midnight UTC, but each scan times out after two minutes and results show only the first two ports. Anonymous users are limited to three scans total, tracked in the browser. A pack of 10 Scan Credits costs 1.99 USD once; each credit unlocks one complete result, and credits do not expire. PRO includes unlimited scans, private results, and longer timeouts; after its 7-day trial, it costs $4.99/month. Free results are public through shareable URLs, while PRO results require authentication. The service collects scan targets, options, and results, and says results are encrypted in its database. It logs scan attempts for security monitoring and may retain those logs for up to one year. Private IP ranges are blocked.
