Domain OSINT

Introduction to Domain OSINT

Domain OSINT (Open Source Intelligence) is a process of collecting and analyzing publicly available information about a specific domain or organization. In the context of information security, Domain OSINT can be used to gather valuable intelligence about potential attack vectors, vulnerabilities, and threat actors targeting a specific organization. It involves using various tools and techniques to collect information from public sources such as search engines, social media, and other online platforms. The information collected can then be used to identify potential security risks and inform security measures to mitigate those risks.
