Sherlock Forensics Port Scanner
What Sherlock Forensics Port Scanner is
Sherlock Forensics Port Scanner is a free desktop GUI tool for finding open TCP ports and identifying services on target hosts. It scans the top 1,000 TCP ports by default, accepts custom port ranges and CIDR ranges, and can scan all 65,535 TCP ports. For open ports, it retrieves service banners that may identify software and version strings. The scanner uses TCP connect scans, completing the full three-way handshake; it does not support SYN scans. Results can be exported to CSV with timestamps, target host, port, protocol, state, and service identification. Each CSV export includes an Ed25519-signed sidecar with the CSV's SHA-256, signature, per-installation public key, and UTC timestamp. The tool identifies ports and services, but does not check findings 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 costs nothing, with no trial period, feature restrictions, or expiry.
