amass

amass is an open-source security tool for identifying and organizing information about assets that may be visible outside an organization’s internal network. It supports security work focused on discovering external assets and understanding how they relate to an organization’s broader network presence. Its work is based on information gathering from publicly available sources as well as active reconnaissance techniques. The software is intended for users who need to examine an organization’s externally visible footprint as part of security analysis.

The tool fits the Security & Privacy category because its primary uses include network mapping, attack-surface analysis, and asset discovery. Open-source information gathering allows publicly available data to contribute to the discovery process. Active reconnaissance provides another method for investigating external assets during security work. These capabilities make amass relevant to security practitioners and other users performing structured research on external network assets.

amass is listed for the Linux platform, so this catalog entry is intended for Linux users seeking the software. Its open-source license identifies it as an openly developed security tool rather than a closed proprietary product. MirrorNest mirrors the official build directly onto its own storage instead of presenting an unrelated package. Before publication, MirrorNest scans the mirrored build for malware, while keeping the official-build source and Linux distribution details clear.
