Nmap vs ScanSearch

Nmap is a free, open-source utility for discovering networks and auditing security. It uses raw IP packets to identify available hosts, services and versions, operating systems, and packet filters or firewalls. Scanning options include TCP and UDP ports, OS and version detection, and ping sweeps. Network administrators can use it to inventory systems, plan service upgrades, and monitor host or service uptime. The Nmap Scripting Engine runs bundled or user-written scripts in parallel for networking tasks such as discovery and vulnerability checks. The suite also includes Zenmap, a graphical interface and results viewer; Ncat for data transfer and debugging; Ndiff for comparing scan results; and Nping for packet generation and response analysis. Most port-scan types require privileged access to send and receive raw packets, although unprivileged users can run connect and FTP bounce scans. Nmap is not a comprehensive vulnerability scanner. End-user use is free, but redistribution in commercial products requires an OEM license. Quarterly OEM licenses start at $9,980.00 per 3 months for eligible small or startup companies.

ScanSearch is a cloud service for on-demand network exposure checks. It runs live SYN scans and detects services on specified targets, which can be IP addresses, CIDR or country ranges, ASNs, or resolved domains. Its Nmap-based engine identifies software, versions, and protocols from more than 12,000 signatures covering over 1,200 services. Depending on enabled modules, results can add TLS/SSL details, HTTP security headers, geolocation, technology stack information, and CVE matches. Results appear in a live dashboard and can be exported as TXT, JSON, or CSV. The REST API supports JSON, webhooks, batch operations, and an official Python SDK and CLI. Separate tools automate Google dork queries and monitor attack surfaces with scheduled scans, change tracking, dashboards, and alerts. Scan data is retained for 7 days on free accounts and 90 days on paid accounts. ScanSearch requires permission for every target and describes its use as authorized security testing, network administration, and research. A free plan and trial are available; the listed paid Internet Scanner plan costs $0.30 a month, billed per kpps/month.
