What Nmap Online Scan is
Nmap Online Scan is a cloud-based web service for scanning internet targets and discovering ports using Nmap. It offers Quick, Service, Aggressive, and Custom scan modes. Users can set port ranges and timing, and enable service-version or operating-system detection. Results can be exported as JSON or CSV.
Free accounts can run three scans per day, with the allowance resetting at midnight UTC. Each scan has a two-minute timeout, and free results reveal only the first two ports. A one-time purchase of 10 Scan Credits costs $1.99; each credit unlocks one complete scan result, and credits do not expire. The PRO subscription provides unlimited scans, private results, and extended scan timeouts. It has a 7-day trial followed by a $4.99/month charge.
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 with user ID and target for security monitoring and may retain those security logs for up to one year. Private IP ranges including 192.168.x.x, 10.x.x.x, and 127.x.x.x are blocked. The service is provided as-is, without guarantees of accuracy, reliability, completeness, or uptime.
