Advanced Port Scanner vs Sherlock Forensics 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.

Sherlock Forensics Port Scanner is a free desktop GUI tool for identifying exposed TCP ports and the services behind them. It scans the top 1,000 TCP ports by default, accepts custom port and CIDR ranges, and can scan all 65,535 TCP ports. For open ports, it retrieves service banners to identify software and version strings. Scans use TCP connect with the full three-way handshake; SYN scans are not supported. Results export to CSV with timestamps, target host, port, protocol, state and service identification. Each export includes an Ed25519-signed sidecar with the CSV’s SHA-256, signature, per-installation public key and UTC timestamp. The scanner identifies ports and services but does not check results against CVE databases or attempt exploitation. It runs on Windows and Linux. Version 0.1.7 supports 64-bit Windows 10/11 as a single executable without installation dependencies or elevated privileges; the native Linux x64 binary requires libgtk-3, libfontconfig1 and libxkbcommon. The free plan has no trial period, feature restrictions or expiry.
