Our verdict on Nmap Online Scan
Nmap Online Scan is a browser-based port and network scanning service for administrators, security professionals, and authorized testers. It scans domain names and IP addresses from the cloud, with quick, service, aggressive, and custom scan types. Users can configure port ranges and timing, then review discovered ports, services, versions, and operating-system results. Because it runs through the web, it suits occasional internet-facing checks without requiring a local installation.
Pricing is structured around a free option, one-time scan credits, and a paid subscription. Basic scanning is available without payment, while the 10 Scan Credits plan costs $1.99 one time and unlocks 10 complete scan results, full service details, operating-system detection results, credits that never expire, and use without an account. The PRO plan costs $4.99 per month and adds unlimited scans, private scan results, and extended scan timeouts. A 7-day trial is also published for the service. This structure is a good fit for infrequent scans or small workloads where predictable, low-cost access matters more than automation.
The standout feature is control over scan depth: quick, service, aggressive, and custom modes cover different inspection needs, while configurable ranges, timing selection, service and version detection, and OS detection provide useful detail. JSON and CSV exports support downstream review, and shareable result URLs make individual findings easy to distribute. The trade-off is a narrow hosted workflow. Without scheduled scans or API access, it is less suitable for recurring monitoring, scripted pipelines, or teams that need automated scan management. Choose it for occasional browser-based Nmap scans and straightforward result sharing; choose an alternative when continuous scheduling, programmatic access, or broader security operations are central requirements.
