Open-source intelligence

Open-source intelligence (OSINT) is intelligence produced from publicly available sources — records, registries, media and online data — collected and analysed lawfully, without recourse to covert or intrusive methods.

In depth

What OSINT means in practice.

The word "open" refers to the sources, not the conclusions. OSINT draws on material that is publicly accessible — company registries, land and property records, court filings, regulatory announcements, news archives, social media, academic and government publications, and a range of specialist databases — and applies analytical skill to extract intelligence that is not visible at the surface level. An individual or entity that appears clean in isolation may present a very different picture when their connections, history and footprint are mapped across multiple open sources.

In private intelligence, OSINT is the primary method for adverse media screening, beneficial ownership mapping, asset tracing and corporate intelligence. It is also the method best suited to producing findings that can be used in legal proceedings: because the sources are public and the methods are lawful, the product can be disclosed, attributed and tested without legal risk.

The limits of open sources

OSINT has natural limits. Subjects who operate carefully will leave a smaller open-source footprint; jurisdictions with opaque registries or restricted media will yield less. In these cases, OSINT findings establish what can be confirmed — and what cannot be confirmed, which is itself significant. The absence of an expected trail is intelligence. Experienced analysts use negative space as a signal, not a gap.
