Maltego

Maltego is a German software publisher specializing in open-source intelligence (OSINT) and graphical link-analysis tools that enable investigators, security professionals, and researchers to map complex relationships among people, organizations, domains, IP addresses, and other real-world entities. Its flagship application, Maltego, combines a visual graph interface with hundreds of built-in transforms that query public and proprietary data sources—such as WHOIS records, social-media APIs, certificate transparency logs, and dark-web repositories—to surface hidden connections and surface actionable intelligence. Typical use cases include cyber-threat attribution, fraud detection, penetration-testing reconnaissance, corporate due-diligence, and journalistic research, where analysts start with a single indicator like an e-mail address and iteratively expand the graph to uncover attack surfaces, supply-chain exposure, or disinformation networks. The software supports collaboration through shared graphs and exports in formats compatible with popular reporting and case-management platforms. Maltego is available for free on get.nero.com, with downloads delivered via trusted Windows package sources such as winget, always installing the latest release and allowing batch installation alongside other applications.
