Advanced Port Scanner vs Pentest-Tools Port Scanner

Advanced Port Scanner is a free Windows desktop utility for finding open network ports and identifying software versions reachable through them. It scans TCP and UDP ports across an IP address range and lets you specify which ports to check. Multi-threaded scanning is available, while a high-accuracy mode checks each computer repeatedly at a slower pace. For LAN administration, the program provides Wake-On-LAN, remote shutdown, and commands that can run on remote computers. Discovered systems can be opened through HTTP, HTTPS, FTP, Telnet, SSH, RDP, or Radmin, with configurable clients for some protocols. Computer lists can be exported to XML, HTML, or CSV, and favorites can be loaded from XML. Radmin connections require Radmin Viewer. Famatech describes the tool for LAN and networking work, and says shutdown actions require authorization. It is distributed as a Windows executable installer and costs nothing.

Pentest-Tools Port Scanner is a cloud-hosted Nmap scanner for discovering open TCP and UDP ports and services on network targets. Users can scan a domain, one IP address, or a network range, including bulk IP ranges. Light scans cover the top 100 TCP and UDP ports; deep scans can extend to all 65,535 ports. Options include service-version and operating-system detection, TCP SYN, full TCP connect, and UDP scanning. Findings can be exported in CSV, JSON, or PDF. The product describes scheduled and parallel scans, notifications, API access, and scan-template workflows, with integrations including Jira, Slack, Microsoft Teams, webhooks, Burp Suite, and GitHub Actions. Internal targets require the VPN Agent, and internal network scanning is an optional add-on. A free plan is listed, but its tier limits are unspecified. Paid plans start at $95 a month, with pricing varying by asset count and billing cycle. The full scanner has a seven-day trial requiring a business email and card; cancel before day eight to pay nothing.
