What Is OSINT? Open-Source Intelligence Explained
In short
OSINT — open-source intelligence — is the practice of gathering and analysing information from lawful, publicly available sources to build a clear, factual picture of a person, company or situation. It draws on registries, websites, public records, news and social platforms, and turns scattered public data into structured insight. It is research, not surveillance or hacking: responsible OSINT uses only legitimately public information and respects privacy and data-protection rules.
A simple definition
OSINT stands for open-source intelligence. 'Open source' here means publicly and lawfully available — not software. It is the disciplined collection and analysis of public information to answer a specific question: who is this counterparty, what is their history, what risks might be involved?
Where the information comes from
Typical lawful OSINT sources include:
- Official company and property registries.
- Company websites, archives and how they have changed over time.
- News, press releases and reputable media.
- Public social media and professional profiles.
- Court and regulatory records where they are publicly available.
What OSINT is not
Responsible OSINT never involves hacking, deception, accessing private accounts, or gathering information a person has a reasonable expectation of keeping private. It focuses only on what is genuinely public and relevant, and it respects data-protection law. Good practitioners are as careful about what they exclude as what they include.
How EZFIN uses OSINT
EZFIN uses OSINT to strengthen the factual framework around a counterparty or situation, then delivers a structured briefing — findings, sources and what they may mean for risk — so a client can decide with clear eyes. Research reduces, but never eliminates, uncertainty.

How is OSINT different from an investigation or surveillance?
OSINT works only from public sources and analysis. It does not involve covert surveillance, deception or accessing private information.
