Angry IP Scanner vs ScanSearch

Angry IP Scanner is a free, open-source desktop tool for scanning IP addresses and ports. It accepts address ranges, random addresses, or files in any format as scan input. The scanner checks whether hosts respond to pings and can optionally resolve hostnames, identify MAC addresses, and scan ports. It also supports NetBIOS information, favorite IP ranges, web server detection, and customizable openers. Java plugins can extend scanning and data gathering with fetchers, pingers, exporters, and feeders. Results can be saved as CSV, TXT, XML, or IP-Port list files, and a command-line interface is available. It runs on Linux, macOS, and Windows under GPLv2. The maker says installation is unnecessary and that the software can be copied and used anywhere. It is described as particularly useful to network administrators monitoring and managing networks. The FAQ notes that some antivirus vendors have flagged the older ipscan.exe, while saying version 3.x is not detected.

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.
